School acoustic solution and design

External environmental noise will interfere with indoor sound and reduce the clarity of listening language and music. Therefore, it is necessary to adopt sound absorption, sound insulation, overcoming sound focusing, vibration echo, and reducing background noise through architectural acoustic design to make audio equipment Play good results.

When the sound emitted by the speaker encounters the wall, top surface, and ground in the indoor transmission, different absorption and reflection will occur. When the reflection and the direct sound are superimposed, the sound will be muddy and unclear, losing the sense of direction and positioning. In severe cases, sound field defects such as acoustic focusing and vibration echo will also occur. At the same time, improper use of materials on various indoor facades will also cause defects or excesses in various frequency bands. Especially large areas and excessive use of the same material will cause deviations in frequency transmission in certain frequency bands.

In order to ensure sound insulation and good speech intelligibility, it is recommended to lay acoustic carpets on the floor and fiberglass ceiling on the ceiling. Use QDBOSS acoustic panels like polyester fiber acoustic panel and fabric wrapped acoustic panel on the walls (which can form high and low walls, and try to avoid a uniform plane) to make the entire venue sound better The three-dimensional sense and the sense of space are stronger. Do not choose glass decoration on the surrounding walls to avoid howling. Since one wall of the anchor classroom is full of broken glass, it is recommended to install soundproof curtains.

Carry out appropriate sound absorption treatment to form a good reverberation in the room, so that the sound is clear and round. On the basis of meeting the requirements for sound absorption, perform sound absorption treatment on part of the wall or the whole wall to avoid large-area strong reflective surfaces.
