Conclude airport noise following characteristics arranged:
1) acoustic pressure is high.During jet-propelled aircraft takeoff, the sound power level of its noise can be equivalent to the noise summation that hundreds thousand of passenger vehicles produce up to more than the 150dB;
2) low-frequency noise is big.According to the foreign literature data, the aviation low-frequency noise is than the high 5-10dB of vehicular traffic low-frequency noise, and high-frequency noises is on average low than traffic noise on the contrary;
3) noise effect scope is wide.Airborne vehicle is in the process of taking off and landing, and its acoustic radiation scope can reach tens of square kilometres;
4) the noise source astable operation makes its noise that produces under different running statuses that notable difference be arranged.With regard to a certain place, only affected by noise in the takeoff and landing process, other the time can ignore.
Consider that noise also is a kind of energy, under certain conditions, can be converted into electric energy when the sound wave of noise runs into barrier.According to this theory, the Britain scholar has manufactured and designed a kind of eardrum formula acoustic receiver, and Germany scientist has proposed to build at both sides of highway the imagination of " noise energy-absorbing wall ", and purpose all is that noise is converted into electric energy.But do not find as yet that up to the present the achievement in research that airport noise can be transformed is seen in report.
