An Analytical Method Is Developed for Describing an Acoustic Field External to Automobiles
Published September 29, 2010 by Society of Automotive Engineers of Japan in Japan
The entire vehicle noise characteristic is described by a HSEA vehicle model and a vehicle external acoustic field model. In this paper we describe how to construct the later one. The key factor of this technology development is based on incorporation of sound diffraction effect. This is achieved with a development of empirical expression of sound diffraction database. This preliminary study shows a promising result to describe an acoustics field external to automobiles.
