Description

Triangular Acoustic Diffuser

technical field

The utility model belongs to the field of diffusers, in particular to a triangular acoustic diffuser.

Background technique

In the architectural interior decoration spaces of various sound recording and playback, such as: opera houses, concert halls, leisure clubs, private theaters, recording studios, HIFI rooms and other interior decoration spaces such as high-end sound construction environments, the design and quality of indoor sound quality Processing is essential. When shaping the sound field environment, we regard the uniform diffusion of the sound field and the complete absorption of low frequency bands as an important sound construction project, which is conducive to the purity and improvement of sound quality.

As we all know, compared with smooth reflective surfaces, diffusers with different structures can effectively avoid sound focusing. When sound waves are reflected by smooth walls, all sound will be reflected in the same direction, and the reflection direction is fixed, depending on the location of the source. And when the sound wave is reflected by the surface of the diffuser with different structures, the generated energy is scattered and reflected in different directions, and has different phase differences. These irregular reflections that form uniform energy will make the human ear subjectively produce a sense of space, and at the same time, when used in the middle and high frequencies, the sound will be smoother and the high frequencies will become more magnificent. The wall or ceiling without diffusion treatment will form multiple reflections and direct sound superposition in the vertical and horizontal directions, which will prolong the reverberation time in the room, and the sound will not dissipate for a long time, resulting in insufficient clarity of indoor sound and difficult to use .
