In addition to the equipment itself and the song, the quality of the replayed sound of the audio equipment is also closely related to the architectural acoustic characteristics of the listening environment. In order for the sound system to achieve the highest performance, it is necessary to perform certain acoustic treatment on the listening room. There are four aspects that need to be considered for the architectural acoustic characteristics of the listening room: reverberation time, diffusion characteristics of reverberation attenuation, frequency characteristics of the room, and ambient noise level. The acoustic characteristics of buildings in listening rooms are different, and the reflection and absorption of sound by different objects are also different. Therefore, it is very complicated to perform acoustic treatment to improve the listening environment and improve the acoustic defects. Whenever possible, it is best to avoid rooms with equal dimensions on any two sides, or a room that is exactly twice the size of the other side, that is, a square or a room with twice the aspect ratio, because rooms with this ratio will produce standing waves and low-frequency acoustic resonance , Causing acoustic staining. The phenomenon that the sound formed by repeated reflections from walls, ceilings, floors, furniture and people in the room persists and gradually attenuates, which is called reverb reverb (also known as reverberation). It is different from echo, which is not a smooth attenuation but a sudden return of sound. The most important indicator for room acoustics is the reverberation time, which is the time required for the attenuation of sound energy to drop to one millionth (60dB) of the original intensity. For a determined room, the reverberation time mainly depends on For sound absorption. For the reverberation time of the Hi-Fi listening room, you can choose 0.4-0.5 seconds. Moderate reverberation time can make the music full and full of voice, longer reverberation time, the sound is more lively and rich, but when it is too long, the sound is easily confused, the clarity of the voice is reduced, the music lacks strength and rhythm, and the reverberation time is too short. The sound is harder, lacks anger, and sounds without reverberation (such as outdoors) often have a dull feeling. If the room has good diffusion characteristics, the sound attenuation is smooth, and the sound feels uniform throughout the room. Any convex surface has the ability to diffuse sound waves, including inclined surfaces, curved surfaces, and convex arc surfaces. When the frequency of diffuse sound waves is controlled by the size of the convex surface, a diffuser plate can be used for processing. When a certain frequency in the sound is excessively strengthened or weakened for some reason, it will destroy the uniformity of the sound in the room. This phenomenon is called sound coloration. For example, standing waves can change the original characteristics of the sound, and peaks appear in certain frequency bands. The method of improvement is to avoid symmetry when placing indoor items. Vision SE is our specialist vision solution offering a wide range of classification services.
