The further technical scheme of the utility model is, described sound absorption material is waveform or distributes according to waveform.
The further technical scheme of the utility model is that described sound absorption material is non-weaving cloth.
The further technical scheme of the utility model is that two panels of described sound absorption chamber are respectively ante-chamber plate and backboard, and the damping coating is arranged on the described backboard.
The further technical scheme of the utility model is, also comprises the sound absorption vibrating device that is positioned at the sound absorption chamber interior, and it is the micropunch panel.
The further technical scheme of the utility model is, on the penetrating sound barrier of described sound barrier fluorescent illuminating device is housed.
The further technical scheme of the utility model is on two panels of described sound absorption chamber the damping sound absorption material is arranged all, and described chamber interior has the above sound absorption material of one deck, and the sound absorption material more than one deck is gapped each other.
Scheme 2:
A kind of method of offset noise is characterized in that, comprises following steps:
The sound absorption chamber that utilizes above corrugated of one deck to have the non-weaving cloth in space enough to cause each other absorbs noise;
The vibrations of noise are converted into energy, described energy converter with the eardrum acoustic receiver with can increase the acoustic resonator that acoustic energy gathers strength and be connected, when just acoustic energy being converted to electric energy from the Burning in Effect of Sound Energy of acoustic resonator during in energy converter.
The further technical scheme of the utility model is, also comprises with pit and damping coating noise is subdued.
Adopt as above the utility model of technical scheme, with respect to prior art following beneficial effect is arranged: by above design and develop the said sound barrier of the utility model, noise can be converted to electric energy, for street lamp or electric motor car charging, but while absorption of noise acoustic energy, thereby reduce near the noise level of road; Measurement result through being undertaken by " Code for measurement of sound absorbing coefficient in reverberation room " GBJ47-83 shows: acoustically effective is good, the sound absorption of centering low-frequency sound wave is particularly outstanding, to the 160-4000Hz sound wave, its sound absorption coefficient α 〉=0.5, to the 160-5000Hz sound wave, its sound absorption coefficient α>0.8, sound absorption coefficient maximum value can reach 0.92 (to the 400Hz sound wave).
