Book excerpt: Aircraft noise in the frequency range above 600 cps which produces the greatest interference with speech communication, can be controlled by practical amounts of sound insulation and can be estimated from the indicated airspeed in most jet propelled or multi-engine propeller driven aircraft. Since interference with speech communication is the most serious effect of aircraft noise, the methods contained in this report for estimation of the insulation required enable the aircraft designers to provide for necessary sound insulation in the earliest design stages. The principal source responsible for noise above 600 cps in the aforementioned aircraft types is the airflow over the fuselage and this noise is found to depend approximately upon the 2.75 power of the indicated air speed. Sound reduction afforded by the insulation is also found to be simply related to the surface density of the batting plus that of any non-porous septa included in the blanket.

Book Synopsis Aircraft Noise by : Oleksandr Zaporozhets
Download or read book Aircraft Noise written by Oleksandr Zaporozhets. This book was released on 2011-05-13. Available in PDF, EPUB and Kindle. Book excerpt: Aircraft noise has adverse impacts on passengers, airport staff and people living near airports, it thus limits the capacity of regional and international airports throughout the world. Reducing perceived noise of aircraft involves reduction of noise at source, along the propagation path and at the receiver. Effective noise control demands highly skilled and knowledgeable engineers. This book is for them. It shows you how accurate and reliable information about aircraft noise levels can be gained by calculations using appropriate generation and propagation models, or by measurements with effective monitoring systems. It also explains how to allow for atmospheric conditions, natural and artificial topography as well as detailing necessary measurement techniques.
