1, hang window cloth to isolate echo.

The indoor environment is basically close to the wall, and the glass panel or glass window on the wall is easy to produce reflected sound. You can hang the lifting window cloth on the window, and pull the window cloth when you turn on the stereo to isolate the reflected sound of the glass. In addition, be careful not to put furniture with glass panels indoors.

2. Use the bookshelf to destroy the reflection on the wall.

Parallel walls, like floors and ceilings, are prone to reflection, forming "multiple echoes" and affecting sound quality. You can use a bookshelf full of books as a sound wave disperser to destroy the reflection of the wall.

3. Lay a thick carpet.

The reflection of sound waves on indoor ground is particularly serious. Loud and transparent speakers are more afraid of high-frequency sound reflected from the ground. Carpets are ineffective at low frequencies, but they can absorb high-frequency reflections. Because you can't put a mat on the ceiling, if there is no carpet on the floor, the sound waves emitted by the sound will reflect back and forth on both sides of the floor and ceiling, resulting in turbid sound.

4. Stick foam on the "specular reflection point" of the tweeter.

The so-called "specular reflection point" refers to placing a mirror at a certain point on the ceiling or the ground, and the high-pitched unit in the mirror can be seen from the listening position. Sticking some small foam blocks on the "mirror reflection point" of each tweeter can effectively improve the sound field environment.
