What is the use of sound absorbing material? Where can it be applied?
1. Control the reverberation time of the sound quality of halls, such as concert halls, theaters, recording studios, studios, audition rooms, conference rooms, multi-purpose halls, gymnasiums, auditoriums, etc. Generally speaking, this is a sound-absorbing material Add appropriate trim for optimal reverberation time.
2. Some public transportation buildings, such as some airport waiting rooms, station waiting rooms, terminal waiting rooms, etc., need to continuously broadcast the departure, arrival or delay time of aircraft, vehicles and ships. Generally speaking, the materials of the sound-absorbing panels are properly arranged like ceilings and walls. On the one hand, this can improve the clarity of broadcast information; on the other hand, it can also reduce the noise of passengers and make the environment quieter.
3. Eliminate sound quality defects such as hall echo and sound focus. When the sound path difference between the direct sound and the reflected sound reaches 17m, the time difference between the two sounds can reach 50ms, and the human ear can hear the echo. In some long halls, the sound reflected from the back wall can easily approach the stage. By placing a strong sound-absorbing panel material on the rear wall, the echo of the seating area can be eliminated. The curved rear wall and dome roof of the building are designed with the hall as the center. If you want to maintain the original interior trapezoid, you can pass these Strong sound absorbing materials are arranged on the inner surface to eliminate the focal point in the hall.
4. Improve the sound insulation effect of thin walls. Such as gypsum board, calcium silicate board, FC board, TK board, fire-resistant magnesium cement board, etc., the interlayer can be filled with porous sound-absorbing materials such as glass wool, rock wool, mineral wool, etc., so as to improve the sound insulation effect of this board wall.
