Practical skills on a subject:Research and assessment of intensity of noise and vibration

Purpose:

This type of researches is carried out under production conditions, and also if necessary – on other objects (settlements, houses, child care facilities and so forth)

The device is necessary for carrying out measurements

IShV-1 (VShV-003M-2 or шумовиброметр other types)

Algorithm actions:

1. To place a microphone on a workplace (or vibrodatchik on a vibrating surface)

To 2-measure intensity of noise (vibration) in DBA

- to establish the toggle-switch in the situation "sound", a measurement sort –«lean», work sort "quickly"

- to take readings from the device by results of not less than 3 measurements, to calculate average size

To 3-measure range of noise (vibration):

measurement sort – in the situation "filter". The switch of frequencies – it is consecutive: 16, 32, 64 etc.

To 4-bring results of measurements in the protocol

To 5-estimate the obtained data with the account the established PDU of noise or vibration in dependences from the studied object.
