Ding Kun noise barrier materials _ [] _ ??Qiaokou wholesale prices Wholesale barriers

 Indoor sound field is a semi-reverberant field. Let the sound source directivity Q barriers for wholesale price, good room barriers constant wholesale R, the insertion loss of the barrier: for a rectangular barrier directly from the sound source and the measurement z connection point, Q is the sound source directivity,, δi for the sound source and the receiver to the i-th side of the barrier difference between the shortest distance and the direct distance. For the reverberant field, and the receiving point in the far-field sound source range, IL = 0, then noise barriers wholesale discount, barrier-free noise reduction. Therefore, when setting the indoor sound barrier requires a higher sound absorption of the room. Acoustic characteristics of noise barriers editing sound frequency doubling of noise barriers wholesale, noise reduction barriers increased by 3 dB. Doubling the height of the barrier, the noise volume increased by 6 dB. If the receiving point from the far field closer to the sound source is equal to the distance barrier where each frequency noise volume increased by 3 dB. If the height of the sound source and the receiving point and the distance are fixed barrier, the barrier in an intermediate position between the sound source and the receiving point when the minimum amount of noise. Therefore, the best location is established near the barrier close to the sound source or the reception point.
