As an important acoustic component, sound-absorbing wedges are mainly used in situations where sound wave reflection needs to be controlled and sound absorption efficiency needs to be improved. The following are some typical application scenarios of sound-absorbing wedges:
 
1. Silencing chamber
An anechoic chamber is an essential facility for conducting acoustic testing and research, requiring sufficient acoustic control capabilities indoors to achieve an acoustic environment close to a free field. The application of sound-absorbing wedges in anechoic chambers is extremely important. They are arranged at various interfaces inside the chamber, which can almost completely absorb the incident sound waves within a certain frequency range, thereby ensuring the accuracy of the test. According to the requirements, the design and material selection of sound-absorbing wedges may vary. For example, some sound-absorbing wedges use metal perforated panels as protective surfaces to enhance their strength and fire resistance.
 
2. Wind tunnel experiments
In wind tunnel experiments, sound-absorbing wedges are used to generate boundary layer wind fields, which have a significant control effect on the profile characteristics of downstream wind fields. Through wind tunnel tests, the influence of different shapes of sound-absorbing spikes on the wind field can be obtained, thereby optimizing the efficiency of wind field debugging.
 
3. Architectural Acoustic Design
In the acoustic design of buildings, sound-absorbing wedges can be used to improve the indoor acoustic environment, reduce echoes and noise. They can be applied in the layout of sound systems in theaters, concert halls, recording studios, and other places to improve the clarity and depth of sound.
 
4. Noise control
Sound absorbing spikes can also be used for noise control, especially in situations where it is necessary to reduce noise within a specific frequency range. For example, in the design of transportation such as airplanes and vehicles, sound-absorbing spikes can be used to reduce noise pollution.
 
5. Acoustic research
In hydroacoustics, sound absorbing spikes also play an important role. They can be applied to underwater sonar systems such as submarines and ships, improving the acoustic environment underwater and enhancing the performance of sonar.
 
Conclusion
 
As a multifunctional acoustic element, the sound-absorbing wedge can be designed and adjusted according to different application scenarios. Whether it is anechoic chambers, wind tunnel experiments, architectural acoustic design, noise control, or underwater acoustics research, sound-absorbing wedges can effectively improve the acoustic environment, enhance the quality and flatness of sound.
