The Acoustic Properties of Different Noise Sources
Jidong J. Yang, Buket D. Barkana · 2009
This paper discusses a method to find the acoustic properties of different types of background noise: highway, airport, subway, restaurant, rain, inside a car, and inside a train. Four parameters are calculated using the auto correlation function (ACF). These parameters are energy (at the origin of delay phi(0)) the amplitude of the first positive peak of the ACF (phiFP), tauPF(delay of phiFP), the amplitude of the first negative peak of the ACF (phiFN).
