The acoustical properties of the room
The sound source in the indoor sound, the sound propagation by closed interface constraints, due to repeated reflection of the surface, the interference phenomenon is complex, the interior sound field is completely different from the outdoor conditions. The interference phenomenon of sound field listening conditions have great effect, summed up the indoor room, main effect of interior sound field is:
1, caused by the reflection of sound.
2, change the transient characteristics of language and music.
3, increase the energy density.
4, change the distribution of acoustic energy in space.
Not even 5, due to the absorption and resonance frequency.
Two, indoor acoustics
When the sound in the space of a point, it will cause a series of sound waves around it, to the sound source as the center, spherical layers outward freely when they encounter obstacles such as walls, floor, part of the sound energy is absorbed, the other part of the sound energy is reflected by the reflection of sound waves the new direction of propagation continues to spread, until the next encounter obstacles, and generate new absorption and reflection. As shown in the figure. Sound in the interior of the multiple reflection and attenuation constant is a very complex acoustic process, have a significant impact on the process of room acoustics. Therefore, we in the indoor speech, listeners always hear the direct sound from the sound source, and then hear the echoes from the wall. That is to say, the room sound field can be regarded as the superposition of a variety of direct sound and reflected sound. In short, the total indoor sound pressure level and only depends on the free field distance between sound source is different. Near the sound source, the total sound pressure to direct sound and reverberation sound (i.e., the sum of the reflected sound) can be ignored, the size and distance of the sound pressure is proportional to the re
