Sometimes I can't know what I can do with my mouth. So today I collected a few vocabulary words for everyone to learn. What's wrong? Give me feedback!
Q: What is the purpose of proliferation?
A: Change the parallel reflection of the sound to avoid uneven sound formation in the space (that is, some places sound loud and some places sound small)
Q: What is the solution to the proliferation?
A: Make the reflective surface irregular, and the technique is diverse.
1, the second residual diffuser----the most standard, the most scientific, the most even distribution of sound waves
2, the gold tower ceiling (or have a regular irregular surface treatment, have an effect)
3, the reflective surface is changed from parallel wall surface to curved shape (thin three clips, curved into an arc, both sides can be positioned on the wall), relatively simple and effective way
4, increase the irregularity of the wall surface (using bookcases, shelves, chairs, furniture, changing the reflective surface of the wall)
Q: What is the purpose of sound absorption?
A: Control the amount and intensity of the reflected sound, because the reflected sound will interfere with the direct sound coming out of the speaker (especially in the case of large volume, small space), so that the sound we hear is cleaner. So everyone feels that the good environment gives the impression that the sound is very clean.
Q: What is the principle of sound absorption?
A: Sound waves are a form of energy. To absorb, it is to transform energy. Generally, it can convert mechanical vibration energy or heat energy. Sound-absorbing cotton is placed in the dragon skeleton. Sound waves cause cotton fiber vibration inside, which consumes energy and causes temperature rise. The energy is consumed, so the sound wave is absorbed a part. The principle is clear. The solution can be imagined by itself. The high point is that the wavelength and energy of different frequency bands are different, and the absorption method is different. The essence is the same. Low-frequency traps, that is, in a reasonable way, consume too much low-frequency reflected energy.
Q: What is the purpose of controlling the reverberation time?
A: The reverberation time mainly determines the tone. When you sing K, you will find that the reverberation time is small, the sound of singing is dry, the wood is wooden, the reverberation time is long, and the sound is not clear enough. When appropriate, the sound of singing is vivid, rich, and hydrated. In fact, this is the truth. The reverberation time of the AV theater is to control the vividness and freshness of the sound. The reason is around us, as long as we carefully discover It is.
Q: How is the reverberation time controlled?
A: Through the absorption, reflection and diffusion to comprehensively control the reverberation time, the general standard has instrument testing. If the requirements are not high, based on your own feelings, the method I recommended above can basically meet the requirements.
