As an audio-visual room, it is necessary to have a good acoustic characteristics, such as reverberation time, resonance mode, sound-staining state, sound field uniformity, and the like. These indicators are closely related to the three-dimensional size of the room and the material texture of the interface between the walls, the floor, the ceiling, and the position of the speakers.
1, put a good speaker
The correct placement of the speakers is the key to good sound reproduction in the room. If you can follow the introduction of the speaker placement in the previous sections of this chapter, it will take a few hours to try to find the proper placement position for the speaker, which will not only achieve good sound reproduction, but also increase the number of sound reproduction effects. Listening to the experience and being able to hear the difference in sound quality. All room acoustics processing is based on the proper placement of the speakers. If the speakers are placed in the wrong position, all the rest of the effort is futile.
2, the length, width and height of the room should have a good proportion
Although in most cases, the room is already built. The ratio of length, width and height has already been fixed. However, if there is a chance to select a room for the listening room, it is best to refer to the ratio of the length, width and height of the room listed in section 3.1 of this chapter in order to avoid standing waves as much as possible. Because this is also a selection condition for the audio equipment to obtain good sound reproduction.
3, try to avoid bare parallel surfaces
If there are bright, face-to-face parallel surfaces without any acoustic treatment in the room, you will hear multiple breaths. Simply apply a sound absorbing material to one of the surfaces, such as sound absorbing foam, ASC's sound absorbing material that eliminates multiple echoes, a small piece of tapestry or carpet-like sound absorbing material, especially ASC's Tube. Special sound absorbing equipment such as Trap can absorb bass at the same time, allowing the reflected sound waves of the side wall to spread and eliminate multiple echoes.
4. Absorbing or scattering the reflection of the side wall and the ground
Try to lay a carpet on the smooth ground before the speaker and the speaker. Place some sound-absorbing or scattering sound waves on the side wall between the speaker and the listening position. Try to avoid reflections such as bare walls and windows near the speakers. surface. American ASC's Tower Trap sound tubes, various sound absorbing foams, and RPG diffuser screens can be effectively used to eliminate side wall reflections. The bookshelves placed on the side of the side wall also spread the sound waves well.
5, let the reflector away from the speaker
Audio racks, power amplifiers, furniture, and other objects placed near the speakers can degrade the sound and sound fields. Therefore, you have to try to move these objects away. For example, move to the back of the speaker. If they cannot be removed, they should be covered with sound absorbing materials.
6. Strive for a room with a very high height and a slope
Although it may not be possible, it is best if you can choose a room with a higher height and a slope to make a listening room. Such a room not only changes the indoor resonance mode between the floor and the ceiling, but also reduces the early reflection at the listening position, making the bass more round and round, and the space is more spacious. The speaker should be placed at the lower end of the ceiling.
7. Balance the absorption of treble and bass
Most rooms tend to absorb too much of the treble, while the absorption of the bass is not enough. Carpets, curtains, and soft furniture are used in conjunction with some materials that absorb bass to keep the reverberation time constant throughout the entire frequency band. Overweight and slow bass is caused by the imbalance of reverberation.
8, move the listening position, let the bass reach the best balance
Standing waves will produce some constant high sound pressure and low sound pressure zones indoors. Try moving the listening position for the best balance. Avoid sitting in the ground near the back wall, because the bass here will be too heavy.
9. Use irregular planes or odd-shaped objects to disturb the remnant graphics.
Deliberately placing some furniture or objects will help to disturb the standing waves formed in the room. Placing large pieces of furniture behind the listening position will spread the reflections of the back walls behind the listener.
