AN INVESTIGATION OF THE NOISE AND OVERPRESSURE GENERATED BY THE SAFETY AIR CUSHION

The results of an experimental study of air cushion noise and over pressure are presented, and methods to reduce these effects are investigated. Free-field studies of inflator noise are made in an open anechoic room, and various silencing devices are tested. Studies are also made of the combined inflator noise and overpressure in a closed passenger compartment. Tests are made for different window openings in the compartment. Results are presented for a new experimental air cushion that draws in air from the passenger compartment as it inflates. Some of the implications of the data with regard to risk criteria for damage to human hearing are discussed. /GMRL/
