Updating the assessment methodology of the acoustic load of flight crew members in the cabins of civil aviation aircraft

Abstract

The article discusses the issues of adjustment, developed in 2007 and supplemented in 2009, of the methodology for evaluating the equivalent level of cabin noise of civil aviation aircraft in Russia. The relevance of the problem is due to high levels of professional hearing loss among the aircrew members of the air force, which is directly related to the lack of unified and competent approaches to assessing the acoustic load on the hearing organ of the aircrew members. The updated methodology contains full-fledged data on noise levels in modern domestic and foreign airliners, data on certification of acoustic efficiency of aircraft accessories, a direct algorithm and formulas for calculating the noise load for the selected periods of flight operation.
