The wooden sound-absorbing panel adopts creative design concepts, combining acoustic theory and aesthetics ingeniously, which produces sound absorption and decorative effects, creating a new trend of acoustic decorative materials. It is suitable for use in a variety of occasions, such as TV centers, cinemas, theaters, concert halls, public halls, conference halls, stadiums, hospitals, schools, hotels, office buildings and residential buildings.
The sound absorption principles used in the wooden perforated sound-absorbing panel mainly include:
1. Helmhertz resonance bodies are connected in parallel after careful calculation.
2. Changing the size of the slit and the back cavity can change the resonance frequency and control the sound absorption frequency characteristics.
3. Increase the porous sound-absorbing material to broaden its sound absorption rate and control the characteristics of the sound absorption rate.
4. After strict calculation of slot, perforation aperture, depth, spacing density, etc., the sound-absorbing panel can have a good sound-absorbing effect in the entire range of 125-4000Hz, and achieve the best sound-absorbing effect in the main frequency band.
