Aircraft noise identification system by correlation technique
Abstract
A Japanese effort at aircraft noise abatement is described. A fully automatic aircraft noise measurement system incorporating the function of identification has been developed. The system discerns the pattern of the cross correlation function between sound signals picked up by two microphones set some distance apart on the ground. The principle of this technique is described and some experimental results are presented.
