Investigation into the noise associated with air bag deployment. Part 1: measurement technique and parameter study.

A new system consisting of commercially available pressure transducers and microphones was assembled and a new software package was developed. This system allows the analysis of pressure-time data using two analysis methods and criteria proposed in the early 1970's. A series of experiments using this system was run over a four year period to investigate the parameters that affect the impulse noise associated with a deploying air bag.
