Noise-Foil panels protect workers, enhance productivity improve communities by reducing reverberant build up of sound levels in enclosed spaces and eliminating noise problems in
outdoor applications.
IAC Acoustics Noise-Foil Sound Absorption Panels
BUILD UP OF MULTIPLE REFLECTIONS
• In close fitting enclosed spaces, reflective surfaces like concrete and steel can produce reverberant build-up of 5 to 10 dB
• Properly selected panels can reduce or eliminate this build-up.
Noise-Foil panels absorb sound reducing the reverberant build up of sound levels in enclosed spaces and eliminating unwanted reflections in outdoor applications.
IAC Acoustics Noise-Foil Sound Absorption Panels
• In larger interior spaces, noise can reflect off walls and flooring and affect workers at a distance from noisy equipment.
• Sound absorptive panels can reduce or eliminate the impact of the reverberant sound path.
Noise-Foil panels absorb sound reducing the reverberant build up of sound levels in enclosed spaces and eliminating unwanted reflections in outdoor applications.
IAC Acoustics Noise-Foil Sound Absorption Panels
• Outdoor sound absorptive panels can maintain the effectiveness of acoustic barriers, even when reflective surfaces are present.

REFLECTIVERETAINING WALL
• Incredible range of human hearing.
• Measure sound energy with special unit called decibel or dB.
• Not linear / arithmetic • Doubling or halving sound
energy = 3 dB difference.• 60 dB to 110 dB =
100,000 X difference in energy.
• “A” Weighting accounts for ear’s variable frequency response vs perfect lab microphone.

• The property of sound that most determines pitch or tone.• Audible frequency range for humans is between:
• 20 Hz – very low bass• 20,000 Hz – very high screech• Sounds & acoustic properties vary by frequency.
OCTAVE BAND CENTER FREQUENCIES
IAC Acoustics Noise-Foil Sound Absorption Panel ApplicationsWhat Frequencies?
• Follows ASTM C-423 standard.• At various frequency bands (groups of frequencies),
measure the difference in sound levels before and after installation of sound absorbing material in a reverberant room.
• Use measured difference to calculate Sound Absorption Coefficient (% of sound energy absorbed by test piece) for each frequency band.
• The average of values from 250 Hz to 2,000 Hz gives a single number, Noise Reduction Coefficient, NRC.
• Approximation of % of sound energy absorbed, 1.00 = 100% full absorption, 0.25 = 25% absorption.
• Bigger number means more absorption.• Some test data will exceed 1.00 due to lab effects.
Sound Absorption Coefficients& NRC: Noise Reduction Coefficient
Acoustics Terminology for Rating Sound Absorbing Panels
