The acoustic wedge is a common acoustic accessory, mainly used in acoustic testing environments such as anechoic chambers. Its principle is to reduce sound reflection in the test space by absorbing sound waves, thereby achieving sound insulation and silencing effects.

The main components of an acoustic wedge are the sound-absorbing material and the wedge structure. Sound-absorbing materials usually use porous materials, such as glass fiber, mineral wool, etc., which have high sound-absorbing properties. The function of the wedge structure is to guide incident sound waves into the interior of the sound-absorbing material, increase the contact area between sound waves and the sound-absorbing material, and improve the sound absorption effect.

In the anechoic chamber, there are many ways to arrange the acoustic spikes, the common ones are staggered arrangement, symmetrical arrangement, etc. By rationally designing the arrangement of acoustic wedges, the sound reflection in the anechoic chamber can be effectively reduced and the ideal sound attenuation effect can be achieved.

The application process of acoustic wedges in anechoic chambers is as follows:

Sound waves enter the anechoic chamber and encounter acoustic wedges. The sound waves are guided by the spike structure to the interior of the sound-absorbing material. Sound waves propagate inside the sound-absorbing material, friction occurs with the fibrous material, and energy is gradually consumed. The sound wave energy is exhausted, thereby achieving the absorption effect.

Acoustic wedges play a very critical role in the anechoic chamber. By absorbing sound wave energy and reducing sound reflection, they provide a good environment for acoustic testing. In practical applications, the arrangement of acoustic wedges should be reasonably designed based on test requirements and site conditions to ensure the ideal sound attenuation effect.
