Sound Absorption and Noise Reduction Design Work Content

- Oct 16, 2018-

Sound absorption and noise reduction design work content: actual measurement or prediction of noise level and spectrum characteristics in the room; selection of sound absorption material or sound absorption structure, according to its type, bulk density, thickness and other parameters to find the corresponding sound absorption coefficient; determine sound absorption the area and installation method of noise reduction processing, etc.

1. Measure or predict the noise level and spectrum characteristics in the room.

2. Determine the amount of noise reduction in the room, including the sound level and spectrum.

3. Determine the amount of noise reduction required for each frequency band.

4. Measure or estimate the original room constant or average sound absorption coefficient in the room, and find the room constant or average sound absorption coefficient that should be processed after the treatment.

5. Select the sound absorbing material or sound absorbing structure, and find the corresponding sound absorption coefficient according to its type, bulk density, thickness and other parameters.

6. Determine the area and installation method of sound absorption and noise reduction.
