The Influence of Indoor Environment on Tuning

1. The influence of indoor sound field on tuning

The sound in the indoor sound field is mainly composed of direct sound, near-reverberation sound and reverberation sound. The reflected sound with a delay of no more than 50 ms is generally regarded as a near-reverberation sound, and the reflection of more than 50 ms is called a reverberation sound.

The direct sound contains the main sound information. The sound intensity at the listening point is inversely proportional to the square of the sound source distance and the frequency of the sound. The farther the distance is, the higher the frequency, the greater the attenuation of the sound. It determines the clarity, presence and intimacy of the sound; the recent reflections have aggravating and thickening the direct sound, making the sound more full and thicker; the reverberation sound makes the sound more full, round and more Magnetic and can widen the ambient sound field.

2. The effect of indoor transmission response on tuning

The indoor transmission response refers to the change of the frequency characteristic of the sound signal after being affected by the indoor environmental electroacoustic characteristics during the sound reinforcement or sound reproduction.

In order to get good environmental electroacoustic characteristics, it is necessary to adjust the interior decoration materials and the room equalizer to change the acoustic energy density, frequency components and distribution of the indoor reflected sound to achieve better sound amplification. The room equalizer is an electronic device that balances the transmission characteristic curve of the room. The purpose of adjusting the room equalizer is to finally make the actual transmission characteristic curve of the room close to straight, to achieve the effect of beautifying the sound.
