Research on Speech Intelligibility of Sound Field inside Passenger Car

Abstract:

Speech intelligibility is one of the most important aspects of the study of sound quality inside vehicle. Speech intelligibility test is the direct approach to decide whether the listening environment inside vehicle is superior or inferior, but it has many short-comings in the process of subjective evaluation which is time-consuming, laborious and difficult of accomplishment. In this article, speech intelligibility index which is an objective evaluation index, is used for analyzing and evaluating the sound quality inside passenger car, and is calculated separately by two methods. By analyzing the factors influencing the speech intelligibility inside vehicle under different conditions, the methods to improve the sound environment are proposed, which can provide a direct significance for improving sound quality inside vehicle.
