Weak current College】 【bar reinforcement required speaker volume calculation method.

<br> <br> Everyone went to a bar or a conference room, at the same time we have this feeling, next to the speaker felt-ear for deaf, simply spend money to buy foreign crime subject to far away from the speakers, .who did not know what to say. Only a few suitable location of the sound volume is possible, but that sounds a bit harsh, bright timbre. It can be said to produce more bad sound rooted in using a professional audio, is a professional audio .to blame. <br> <br> Experience; bar audio use speaker's logarithm = area ÷ 30 through so many point of a control, not only solve the large environment sound sound pressure (volume) is insufficient, but also makes the whole space of .any corner of the sound is the same, as long as you are in the design of the sound space, we listen and treatment is equal. We are living in the so-called best to listen to the "Emperor-tempo" and design of .the equipment are above uses Hyun-6202 bookcase box, when the speaker is not only sound fever (good) but also in public occasions, in particular when used on the "create", "a common centralized sound field, there's a common failing is .the sound field not uniformity is too large, the sound field of the maximum sound pressure level and field of minimal sound pressure level and acoustic field minimum field pressure level difference between the loudness. Lead speaker sound is too large, the front of the audience deafening ., unbearable, and district voice was too small, loudness, this is because the sound field layout of unreasonable, and not as professional audio to blame, if it is destroyed or multi-function Hall, singing and dancing activities, you must use a professional .sound system configuration to meet the standards of the sound pressure level. <br> <br> The existence of the above solutions in two ways: <br> <br> First, is the use of lifting and speaker, lifting the main speakers at .the sides of the estuary of the small stage, this increases their sources and viewers, and speaker on top, over the air, the acoustic features of radiation, acoustic power is not the human body and hair sound absorption, sound propagation distance so that the .back area of acoustic sound pressure level have been greatly enhanced, when acoustic wave uniformity when less than 6dB reached the national standard for secondary grades, but it is difficult for hoisting speaker, aluminum-framed, rack-mountable speaker, if the Hall area of .more than 120 sqm and above, can sound field in the middle or the rear retro auxiliary speaker to compensate for insufficient after field sound pressure level. <br> <br> Second, if the only bar in the Hall to play music, acoustic sound .pressure level control in 60-90dB (distortion), not for singing and dancing activities, you can use distributed sound field background music mode, the speakers scattered around the halls, according to the empirical formula: SPK (p) = S (space) ./ 30 (rectangular sound field), decision number of speakers, amps total power at 2W/M2 or more. <br> <br> This pattern of the sound field characteristics for sound timbre the non-uniform degree is smaller, the tone harmony .with nature, if you feel the lack of sound field Center volume, can be equipped with two hoisting field sound device to compensate for. The disadvantage of this model is sound, if you use curl speakers (famous fever speaker) and Tsinghua power amplifier ( .technical parameters is very high, reached the national advanced standard) two models are all sound very good unit, should get more high-quality sound effects! <br>.
