January 2017 Report No W6039/02 Issue 1 2

1. INTRODUCTION

In November 2016, ESG was commissioned by LIDL UK GmbH to carry out a noise assessment at

LIDL, 151 Colne Road, Burnley Street, Lancashire, BB10 1EH. The noise assessment was

required for an application to vary condition 11 of planning application APP/2006/0509, dated 08

June 2006.

Planning condition 11 specified a restriction on delivery hours as follows;

“Deliveries to the site shall only be made between the hours of 0730 and 2000 Monday to

Saturday and between 0900 and 1700 Sundays and Bank Holidays”

The current delivery hours restriction is affecting the store efficiency and management and is also

causing logistical issues in regard to staffing and shelf replenishment. If the store was able to

accept goods delivery at other times including night time, this would assist in addressing the

current issues.

LIDL UK GmbH intends to apply for a variation of the existing planning permission to allow

unrestricted goods delivery hours at the store.

This report presents the findings of a noise assessment related to the potential noise impact at

nearby residential premises if the restriction on goods delivery hours for the present delivery

arrangement was to be amended as described above.


2. NOISE ASSESSMENT CRITERIA

BS 8233: 2014 Guidance on Sound Insulation and Noise Reduction for Buildings

BS 8233:2014 details guideline values for acceptable noise levels inside private dwellings, and is

similar to criteria referenced in World Health Organisation (WHO) (1999) Guidelines for

Community Noise. The referenced guideline values are provided in Table 1.

Table 1. Guideline ambient noise levels inside private dwellings

Activity Location 07:00hrs to 23.00hrs 23.00hrs to 07.00hrs

Resting Living room 35 dB LAeq, 16h -

Dining Dining room/area 40 dB LAeq, 16h -

Sleeping Bedroom 35 dB LAeq, 16h 30 dB LAeq, 8h

World Health Organisation (1999) Guidelines for Community Noise

As referenced above, the WHO 1999 Guidelines for Community Noise details acceptable ambient

noise levels to be applied when considering noise impact inside private dwellings. Specifically,

Table 4.1 in the guidelines advises the following;

35 dB LAeq, T for Livings rooms (based on a 16hr day)

30 dB LAeq, T for bedrooms (based on an 8hr night)

The guidelines also state “For a good sleep, it is believed that indoor sound pressure levels should

not exceed approximately 45 dB LAFmax more than 10-15 times per night.”

World Health Organisation (2009) Night Noise Guidelines for Europe

The EU Environmental Noise Directive 2002/49 placed an obligation on member states to

implement measures to control noise from major infrastructure. The WHO, working with the

European Commission, developed night time noise guidelines to assist member states in

developing appropriate legislation for noise control.

The WHO 2009 guidelines identify a threshold above which it was considered that sleep

disturbance would likely occur, dependent of course on the level of exposure. A threshold of 42dB

was suggested, above which, occupants in private dwellings were likely to be awoken.

The guidelines also comment on the extent of noise impact associated with sound intensity and

frequency.


BS4142:2014 Method for rating industrial and commercial sound

The guidance in British Standard (BS) 4142:2014 details the methodology for evaluating the

likelihood of complaints at nearby external noise sensitive receptors from sound associated with

industrial or commercial activity.

Assessment of the likelihood of complaint is made by direct comparison of the ‘Rating Level’ of the

industrial or commercial sound source (the specific sound level, adjusted to account for particular

characteristics including tonality and impulses) compared to the background sound level (LA90).

BS4142: 2014 states that a calculated rating level which exceeds background sound levels by 10

dB or more is considered indicative that noise complaints are likely and the impact is “significant

adverse”. A difference of up to 5db is said to be of marginal significance and the impact is

“adverse”. If the rating level is 10 dB below the background noise level then complaints are

considered highly unlikely.

British Standard 5228:2009 Code of Practice for Noise and Vibration Control on

Construction and Open Sites

The methodology as specified in BS5228:2009 was implemented during the night time baseline

noise survey at the site. The standard defines the activity LAeq method for use with a stationary

activity at a clearly defined source location.

The LAeq method as specified in BS5228: 2009 was used to determine the sound pressure level

of the activity noise at the façade of the noise sensitive property and configured in SoundPlan

Essential 4.0 modelling software.

SoundPlan Essential 4.0

SoundPlan Essential software utilises accepted UK noise calculation methodology including

standards BS5228-1:2009 and ISO9613-2:1996 and is considered the industry standard for noise

propagation simulation. The software was used to determine the extent of noise propagation

associated with goods delivery activity at the Colne Road LIDL store, Burnley.

A model replication of the LIDL Burnley store was generated in SoundPlan using site specific

topographic survey data provided by the client, in addition to aerial photography (Google imagery)

and is a scaled replication of the site in terms of landform, and elevations and buildings position

and orientation.


Sound pressure level measurement data recorded during HGV goods delivery at Colne Road LIDL

store on 2 November 2016 (Appendix B) was used to calculate activity related Sound Power

Levels (PWL) and assigned as activity related noise sources for the purpose of SoundPlan

modelling.

Sound Power Levels were calculated and then modelled in SoundPlan for the following activities;

HGV arrival and manoeuvring to the goods delivery bay.

Goods unloading activity from the HGV trailer.

Data output from SoundPlan modelling of the site was then used carry out BS4142 Rating Level

Assessments.

3.2 Calibration

The sound level meter was calibrated using an acoustic calibrator prior to commencement of the

noise survey.

3.3 Survey Details

A noise survey was carried out on 2 November 2016 between 07.40hrs and 08.40hrs at a position

next to the delivery ramp area at the rear of the store as shown on Figure 1 (Appendix A). The

noise survey was carried out during goods delivery activity which took place from the rear of the

stationary delivery HGV. The survey position was set up at approximately 2m distance from the

front of the delivery HGV position. The purpose of the survey was to accurately measure the noise

levels associated with goods delivery at the store.


A further noise survey was carried out between 01.35hrs and 01.46hrs on 2 November 2016 on

the footpath at the nearest noise sensitive property (NSP) situated at Edmund Street, adjacent to

the LIDL store goods delivery bay. The purpose of this survey was to establish the existing night

time baseline noise level at the location, during a quiet period when most people are normally

asleep, and therefore more sensitive to noise disturbance.

Direct line of sight between from the nearest NSP to the LIDL store delivery area was obstructed at

ground level by a 1.8m high stone wall situated at the site boundary and along Edmund Street.

The LIDL store and the goods delivery area are situated at a lower ground elevation

(approximately 2m) than the adjacent roads and properties.

The noise surveys utilised a Type 1 sound level meter equipped with a windshield, and secured to

a tri-pod 1.2m above ground.

The noise survey positions are identified on Figure 1 (Appendix A).

3.4 Meteorological Conditions

Climatic conditions observed at the monitoring locations during the noise survey periods were as

follows;

02/12/2016 – 30% cloud cover, dry, wind speed <1m/s, temperature ranging from 5 to

6oC.


4. SURVEY LOCATIONS

Store Delivery Area

The survey location at the goods delivery area comprised a hard surfaced car park and goods

delivery bay area at the store rear. There was no soft ground between the survey position and the

noise source location. The survey position was located at the corner of the LIDL store and the rear

goods delivery bay.

The noise survey of goods delivery activity at the store commenced while it was still closed

(07.40hrs to 08.40hrs). The car park was therefore not in significant use at the time. There were

however, a number of vehicle movements on nearby roads (Colne Road in particular) which

contributed to observed ambient noise levels.

Nearest Noise Sensitive Property

The survey location at the corner of Edmund Street and Rylands Street comprised a surfaced

footpath near to the LIDL store as shown on Figure 1 (Appendix A). The ground between the

survey position and the store delivery area was hard surfaced.

During the night time baseline noise survey (01.35hrs to 01.46hrs) at the noise sensitive property,

traffic noise from nearby roads was clearly audible. Noise from the LIDL store condenser fans was

also audible at the survey position.

During the night time noise survey, the position of the noise survey equipment began to attract

attention from a number of local individuals. The night time noise survey period was stopped after

10 minutes on health and safety grounds of the attendant engineer. Notwithstanding this, the

baseline noise survey was still considered to be representative of existing night time noise levels at

the location.

Noise measurement reports related to store delivery activity and also the baseline night time noise

survey are provided in Appendix B.

HGV Delivery

Noise associated with the delivery HGV accessing the goods delivery area at the store was also

recorded at the beginning of the survey period. The HGV accessed the store car park and

manoeuvred to the store rear where it then reversed into the goods delivery bay. The HGV

manoeuvring took place between 07.42hrs and 07.44hrs (approximately 2 minutes). The HGV then


left its engine running for a further 3 minutes between until 07.47hrs, after which the engine was

turned off and goods unloading activity commenced.


5. SURVEY DATA

Noise survey data was downloaded from the sound level meter using deaf defier software. Tables

4a and 4b detail the sound level measurements at the LIDL store delivery area during goods

unloading (07.40am) and also at the nearest potentially noise sensitive property (NSP) at Edmund

Street during the night time (01.35am).

6. SOUNDPLAN MODELLING

6.1 Modelling Parameterisation

SoundPlan modelling software was utilised to determine noise propagation associated with HGV

access and goods delivery at the Colne Road LIDL store, Burnley. The model was parameterised

based on actual noise survey data recorded on 2 November 2016 of a HGV arrival and

manoeuvring to the store delivery bay and then goods unloading activity.

The SoundPlan model included a three dimensional replication of the topographic and structural

detail of the assessment area. The ground type and structural detail such as bunds, walls and

reflective surfaces were replicated. Sound Power Levels (LWA) of noise sources associated with

goods delivery and unloading activity were then assigned to the relevant positions within the site

model.

Noise propagation simulations were then performed to determine the sound pressure levels (SPL)

associated with goods delivery and unloading activity at the façade of the nearest NSPs.

Two SoundPlan models were utilised for the noise assessment. One model replicated the HGV

arrival at the site. The second SoundPlan model replicated goods unloading activity and noise

propagation at NSPs.

General parameters assigned to the SoundPlan models in the assessment were as follows;

HGV Arrival – Assigned as a single line noise source at 2m height above ground

(calculated Sound Power Level (PWL) based on actual sound pressure level (SPL)

measurement at 10m). (SPL of source passing at 10m distance of 70dB(A) = source PWL

of 101 dB(A))

Goods Unloading– Assigned as a single point noise source at 2m above ground (calculated

Sound Power Level (PWL) based on recorded sound pressure level (SPL) at 2m) (SPL at

2m from source of 66.6dB(1hr LAeq) = source PWL of 83.6dB(A))

Noise sensitive properties – Assigned as single point receivers fixed at building façade at

ground-floor and 1st floor height for bedroom (1st floor receiver at 2.8m height above

ground).

Buildings and structural dimensions replicated in SoundPlan models were based on survey

data (AutoCAD file) provided by the client and are to scale.

Barriers – 1.8m height wall replicated at the site boundary along Edmund Street.


Ground absorption – Ground type assigned as “hard” with zero ground attenuation.

Mitigation areas – No mitigation areas included in the model.

SoundPlan models were used to simulate the digital ground model (DGM), line and point noise

sources, single point receivers and elevation points, to generate noise contour plans for each

simulation scenario. Noise contour plans therefore accurately illustrate noise propagation for the

study area (see Appendix D).

6.2 Modelling Results

SoundPlan modelling results for the existing HGV arrival and goods unloading activity are

presented in Table 5. The SoundPlan model results relate only to noise attributed to LIDL store

HGV arrival and goods unloading, and exclude noise associated with other existing developments

in the general surrounding area.

(6) Rylands St 56 40.9

Note: *Activity sound level LAeq at property façade (1st floor bedroom)

Noise contour plans were generated in SoundPlan which show the extent of noise propagation

from the HGV arrival and goods unloading activity (Appendix D). Noise levels are illustrated by

coloured contours (Figures 3 and 5). The noise contour plan clearly illustrates the extent of noise

propagation associated with goods delivery activity at the LIDL store. Noise levels at the façade of

each NSP are detailed on Figures 2 and 4 for ground and first floor elevations.

To fully consider the noise impact at nearby NSP’s associated with night time goods delivery, it is

necessary to compare the modelled activity related noise levels against measured background

noise levels from the baseline noise survey to provide a Rating Level assessment in accordance

with BS4142: 2014.


7. BS4142:2014 RATING LEVEL ASSESSMENT

British Standard (BS) 4142:2014 describes the methodology for determining rating levels for noise

generated from industrial and commercial activity, and assessing whether the noise is likely to give

rise to complaints from occupiers of nearby noise sensitive property.

A rating level is said to be the specific noise level plus any adjustment for characteristic features of

the noise source. BS4142 details a sliding scale of penalties to be applied to noise calculations

where the source has identifiable tonal or impulse characteristics.

A description of the noise observed during goods delivery at the LIDL store would include

occasional and intermittent impulses of bangs and clatters, and also occasional low rumbles of

cage movements within the trailer (approx. 2-5 seconds duration). There was no continuous

humming or drone noise type observed during goods unloading.

Impulse related noise characteristic penalties were therefore considered applicable for the Rating

Level assessment. An impulsivity correction of +6dB (A) was applied to the Rating Level

Assessment.

The proposed night time goods delivery scenario at the LIDL Burnley store was used to calculate a

noise rating level for the nearest noise sensitive property on Edmund Street. The Rating Level

Assessment result provides an indication of the likelihood of noise complaint.

BS4142:1997 states ‘A difference of around +10 dB or more indicates that complaints are likely’.

9.

The Rating Level assessment indicates that the noise impact from night time goods delivery would

be “adverse” to “significant adverse” at the adjacent Edmund Street noise sensitive property.

However, BS4142:2014 also states that the estimated impact must also be considered within the

context of the activity, site and location. In this regard, it is suggested that the following factors

must also be taken into account;

The Rating Level assessment was highly conservative as the measured Specific Sound

Level of goods delivery included a five minute period of measurement when the HGV was


manoeuvring into position and then the engine was left running for a further three minutes.

If deliveries restrictions were lifted, one of the suggested requirements would be the HGV

engine being turned off during after manoeuvring. This would reduce the period of engine

noise to approximately 2 minutes.

The number of HGV goods deliveries is presently one per day (currently 7.30am). The low

number of daily deliveries means the potential for noise disturbance is very limited.

BS4142:2014 relates to exposure of external noise only. If goods delivery hours were to be

unrestricted, then the noise impact would mainly be associated with the likelihood of sleep

disturbance occurring during night time. The associated noise impact would be indoors. To

assess noise impact indoors, BS8233 and also WHO guidance should be considered as

previously referenced.

HGV arrival and Manoeuvring

For completeness, SoundPlan modelling included the HGV arrival and goods unloading to

determine related noise levels at the nearest NSP. The SoundPlan model indicated a peak sound

pressure level of 61 dB LAeq at the façade of the nearest NSP on Edmund Street during HGV

manoeuvring. A reference Sound Power level (PWL) of 101 dB(A) was calculated for the HGV

manoeuvring activity (Section 6.2) and assigned as a line noise source for acoustic modelling.

It was noted during the noise survey that the adjacent nearby NSP’s were not located in a

generally quiet neighbourhood. At the time of the night time baseline survey, there was significant

existing ambient noise levels, particularly from traffic on nearby roads.

The 1hr LAeq noise survey measurement of 66.6 dB (A) of goods delivery activity also include the

initial period of HGV manoeuvring and engine idling. The Rating Level Assessment therefore

accounted for all noise associated with a HGV goods delivery taking place at the LIDL store for the

approximate 1 hour duration.


8. BS8233: 2014 AND WHO ASSESSMENT

The main noise impact attributed to potential night time goods delivery at the LIDL store is not

determined in a BS4142 Rating Level Assessment which only addressed external noise received

at the building façade. To assess the noise impact on occupants inside a private dwelling, the

attenuation associated with the building structure and materials must also be considered.

WHO guidelines suggest that with open windows (worst-case) for ventilation, a further noise

attenuation of approximately 15dB LAeq would be expected for a typical domestic glazed window

and usual bedroom furnishings.

Remembering that the goods delivery and unloading activity sound pressure level at façade was

49.4 dB, and the applicable impulsivity penalty was 6 dB, which resulted in an equivalent activity

sound pressure level of 55.4 dB(A). A 15 dB(A) attenuation for an open window at the NSP would

result in a sound pressure level inside the private dwelling of approximately 40.4 dB(A). This would

be above the 30 dB(A) guideline threshold as referenced in BS8233:2014 for which sleep

disturbance may occur.

However, it was noted during the noise survey that the properties along Edmund Street facing the

LIDL store, were boarded up at the time and were not in occupancy. The nearest occupied

dwelling was actually located on Rylands Street, were the predicted activity sound pressure level

at the property façade was 40.9 dB(A), with a 6dB impulsivity penalty, this become 46.9 dB(A). A

building attenuation of 15dB would indicate an activity sound pressure level inside the property at

Rylands Street of 31.9 dB(A), which would unlikely cause sleep disturbance to the occupants.

If the windows of the nearby private dwellings were to be closed, then noise mitigation of around

26-32 dB LAeq would be expected, which would reduce the sound pressure level inside the private

dwelling from the goods delivery and unloading activity to approximately 20.9 to 26.9 dB LAeq for

Rylands Street residents.

It is clear from the BS8233:2014 assessment that the goods delivery related sound pressure level

inside the nearby private dwelling at Rylands Street would be well below the level expected to

cause sleep disturbance.

If the premises on Edmund Street were to become occupied, then there would be a potential for

sleep disturbance to occur with an open bedroom window. If the windows were kept closed, the


sound pressure level inside the Edmund Street property would be approximately 28.5 to 34.5

dB(A) which is unlikely to cause significant sleep disturbance to the occupants.


9. DISCUSSION OF ASSESSMENT RESULTS

The assessment indicates that residents in nearby private dwellings at Ryland Street would not be

adversely affected by noise from night time goods delivery at the LIDL Burnley store in terms of

sleep disturbance. The anticipated noise levels inside the property during goods delivery and

unloading activity were below the thresholds referenced in BS8233.2014.

The noise assessment indicated that sleep disturbance was possible for occupants in property on

Edmund Street and facing the LIDL store if bedroom windows were left open. Sleep disturbance

was considered unlikely if the windows were closed. However, the Edmund Street properties

facing the LIDL store were unoccupied at the time of the noise assessment, and due to the

appearance of disrepair were considered unlikely to be occupied in the near future. The noise

assessment findings for those particular properties should therefore be viewed in that context. At

present the nearest occupied properties that could be affected by night time goods delivery at the

LIDL Burnley store are those situated on Rylands Street.

Guidelines referenced in BS8233:2014 were followed to determine the likely ambient noise levels

inside the nearest private dwellings based on the worst case scenario of an open window for

ventilation (comparative to 15 dB sound attenuation). The determined internal ambient sound

pressure level of 31.9 dB(A) was marginally above the BS8233: 2014 and WHO guideline

threshold of 30dB LAeq for sleep disturbance. It was considered that sleep disturbance for the

occupants of Rylands Street properties was therefore unlikely, particularly in the context of the

existing ambient noise climate.

It should also be noted that a single goods delivery each day at the store comprising a very short

duration for manoeuvring into the delivery bay, and then again for exit, represents a very limited

duration in the context of a typical 8hr sleep.

If the store delivery hours restriction was lifted, it would be good practice to implement a number of

management practices to further mitigate the noise impact. The following noise management plan

measures are recommended at the store.

Deliveries to be scheduled at timings which are nearest to the store opening hours as

possible.


Delivery driver to contact the store to advise of the likely arrival time to allow the store to

prepare for the delivery e.g. ready to open doors to prevent the driver having to attract the

store occupants attention by shouting.

Service doors and shutters to be well maintained to reduce associated noise during

delivery.

The lorry engine shall be turned off at the earliest opportunity when the vehicle is correctly

positioned at the store delivery area.

The lorry driver shall not over rev the lorry engine unnecessarily or use the horn.

The lorry and store FM radios or sound systems shall be turned off prior to and during the

goods delivery.

All employees shall ensure voices are kept low, and that no shouting occurs during the

delivery period.

Movement of cages within the goods delivery vehicle and goods reception area shall be in

a controlled manner, so as to minimise any potential impulsive noises.

Upon receipt of any noise complaints related to goods delivery activity, LIDL shall ensure a

thorough investigation is carried out into the cause of complaint. The investigation shall

determine the likely noise source and also propose a suitable noise mitigation strategy,

agreeable to both parties, and implemented during deliveries.


10. CONCLUSION

A noise assessment was carried out to determine the potential noise impact associated with night

time delivery of goods at the LIDL Burnley store. The assessment methodology as detailed in

BS4142:2014, and also B5228: 2009 and 8233:2014 was followed. Guidelines provided in WHO

guidelines of 1999 and 2009 were also considered. SoundPlan Essential 4.0 was used to model

noise propagation associated with goods delivery activity.

The outcome of the noise assessment was that noise associated with goods delivery at the LIDL

Burnley store during the night time period would have no significant adverse impact on residents at

nearby Rylands Street private dwellings which were the nearest occupied property. This would be

further ensured by implementation of the referenced noise control and mitigation measures which

could be suitably conditioned in the planning permission.

Properties on Edmund Street facing the LIDL store were not in occupancy at the time of

assessment and the predicted marginal noise impact was therefore not considered applicable at

present.
