5 Sound Seal is a leading manufacturer of commercial and architectural acoustic sound control products & materials. Offers a wide product selection to the acoustics & noise control markets. Over 37 years of expertise, Sound Seal can offer the technical support and know how to solve any noise problem. Sound Seal Agawam, Massachusetts Established: 1978 Dedicated staff to guide customers and project teams through step by step selection and specifications, ensuring we get it right the first time.

6 Sound Seal acquired INC, an acoustical metal panel company, in October 2014 Sound Seal acquired IAC Acoustics assets in December IAC Acoustics (Formerly INC)- North Aurora, IL IAC Established: 1949 INC Established: 1968 Moving forward the company operates as IAC Acoustics, A Division of Sound Seal.

7 IAC Acoustics Noise-Foil Sound Absorption Panels 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. BUILD UP OF MULTIPLE REFLECTIONS In close fitting enclosed spaces, reflective surfaces like concrete and steel can produce reverberant buildup of 5 to 10 db Properly selected panels can reduce or eliminate this build-up.

8 IAC Acoustics Noise-Foil Sound Absorption Panels Noise-Foil panels absorb sound reducing the reverberant build up of sound levels in enclosed spaces and eliminating unwanted reflections in outdoor applications. 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.

9 IAC Acoustics Noise-Foil Sound Absorption Panels Noise-Foil panels absorb sound reducing the reverberant build up of sound levels in enclosed spaces and eliminating unwanted reflections in outdoor applications. Outdoor sound absorptive panels can maintain the effectiveness of acoustic barriers, even when reflective surfaces are present.

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.

12 IAC Acoustics Noise-Foil Sound Absorption Panel Applications What Frequencies? OCTAVE BAND CENTER FREQUENCIES A-Scale 63 Hz 125Hz 250Hz 500Hz 1000 Hz 2000 Hz 4000 Hz 8000 Hz 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.

13 Acoustics Terminology for Rating Sound Absorbing Panels Sound Absorption Coefficients & NRC: Noise Reduction Coefficient 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.

14 Noise-Foil Metal Sound Absorption Systems High sound absorption performances, Noise Reduction Coefficients of Data provided for 125 Hz and 4 khz for industrial applications. Variety of thicknesses 2", 2.5", 4" Available fill protection options with spacer with adjusted acoustic performances.
