The corrugated sponge of convex-concave is presented in a kind of one side that specially treated is formed, its inside is full of small spaces and half open-celled structure, energy
It is a large amount of to absorb the acoustic wave energy injected, attenuation is played to sound wave, the interference of reflected sound is reduced and echoes, improve the pure of sound
Degree.The cotton that absorbs sound has the hole and bubble of a large amount of inside and outside unicom, when sound wave incident to wherein when, air in gap can be caused to shake
Dynamic, due to the viscosity resistance of air, the friction of air and hole wall, makes quite a few acoustic energy change into thermal energy and be consumed.This
Outside, when air adiabatic compresses, heat exchange constantly occurs between air and hole wall, due to conduction of heat, can also make a part
Acoustic energy changes into thermal energy, so as to reach the effect for also having sound-absorbing to the buffering of sound.The effect of sound-absorbing and the size of perforate, whole
The thickness of cotton is related, and i.e. enabled sound-absorbing can only also inhale sub-fraction if too thin, and in addition perforate should not be too large, excessive not have
Sound-absorbing effect, crosses slight drag too loud noise and cannot get through.Sound absorption cotton can sound-absorbing can also play some soundproof effects because in sound
Sound produces friction by meeting when sound-absorbing and sound absorption cotton, the action of original sound can have been buffered, and then lowers original sound
The penetration power of sound.
Further, in the ventilating sound-proof device of the present embodiment, the surface of babinet is provided with vibration damping sheet.Above-mentioned vibration damping sheet can be with
So that wind turbine 3 when work, will not cause overall strong vibrations, so that being loosened between each part, installation strength
