The introduction
The acoustic sound diffuser panel is mainly used to deal with the echo in the space. This material is an excellent substitute for sound absorption in acoustics, and it is also a good supplement in sound absorption treatment. The acoustic sound diffuser panel will not eliminate the energy of the sound but can achieve a good sound mixing effect.
The function
As we all know, acoustic defects such as standing waves, comb filtering, resonance and degeneracy are prone to occur in a small regular space, which greatly enhances certain frequency components of the sound, resulting in distortion of the original tone or coloring effects. In the mixing space, the impact of such defects is particularly obvious, and the above phenomena are mainly caused by the following reasons:
1. The size of the space in the ordinary small space is small, and the wavelength of the low-frequency part is similar or the wavelength of the low-frequency part of the ground is in a simple multiple relationship, and the room has a resonance phenomenon.
2. When the sound wave is reflected back after it touches the interface, the absorption coefficient of the wall is too small, and the reflected sound energy is still large, and it interferes with the incident sound wave, resulting in a standing wave or comb filtering phenomenon.
3. The geometric dimensions of the room are in integer ratios, causing the indoor axial resonance and tangential resonance frequencies to overlap or be similar, resulting in degeneracy.
4. A strong reflection in the mixing space will mislead the audience's judgment on the sound image positioning and affect the distribution of the indoor stereo field. When the direct sound from the speaker on the one side is reflected by the wall on the other side, it will reach the human ear on the other side slightly later than the direct sound from the other side speaker reaches the human ear, and there is a very small time gap. . When the reflected sound intensity is large enough or the directivity is strong enough, it will disturb the brain's judgment of the sound source and cause the sound image localization shift.
Therefore.acoustic sound diffuser panel is important in our life.
