Vehicle engine operating noise processing procedure determines characteristic values by comparison reference mode and operating mode sound frequency distribution

A vehicle engine operating noise (7, 8) processing procedure determines characteristic values such as peak factors, impulse probability and level and root mean square level in recorded body (2, 6) or air sounds by subtraction from characteristics when driven in a reference mode (1) and combination (...
