[Hygienic assessment of the overall noise load in civilian aviation crews].

The contributors give a hygienic assessment of the overall noise load in Soviet Civil Aviation crews' labour conditions and propose an original technique for noise load measurements during the flight, including noise level measurements in the cabin, effectiveness of individual noise protection means, and measurements of noise resulting from individual radio communication devices. The communication devices are considered to bear major responsibility for noise load in modern aircraft crews. Conclusions are made with regard to the health related factors of noise load in off-flight state (when in the landing field) and off-duty conditions (at rest in airport hotels and recreation sites).
