汽车声音评审系统评价指南
INTRODUCTION
Why do subjective testing and analysis in automotive
sound quality investigations? One might ask why bother
with the trouble of conducting subjective testing in the
first place? In the authors' experience, conducting subjective
jury evaluations of automotive sounds has led to a
deeper understanding of those sounds and the way that
potential customers react to and sometimes appreciate
automotive sounds. The following is an attempt to
describe subjective testing and analysis as applied to
sound quality, and its relevance to gaining this deeper
understanding. The remainder of this document draws
upon the experience of the four authors and, as a result,
may be biased toward the techniques they commonly use
or have found to work well in their automotive sound quality
studies. However, an attempt has been made to
address other techniques commonly used by other
researchers in the general field of product sound quality.
Although not a comprehensive document, it is hoped that
this paper will provide a set of guidelines which
addresses a majority of the issues and techniques used
in the field of automotive and general product sound
quality. It is hoped that this guide will act as a springboard;
a launching point for your own individual investigation
into subjective testing and analysis for automotive
sound quality.
DEFINITIONS – It is appropriate to begin with a few fundamental
definitions of terms used throughout this document.
