Listener Training and Repeatability for Automobiles
Listener Training and Repeatability for Automobiles
Presented at the 104th Convention of the AES, Amsterdam (1998 May)
ABSTRACT
The benefits of trained listeners has been well established for listening in rooms and at computer workstations [1],[2],[3]. Recent studies have illustrated the use of a self administered PC-based training program to improve listeners' ability to reliably identify and rate different types of spectral peaks and dips which have been added to a variety of programs (i.e., resonance detection)[4],[5]. Similar investigations have indicated that critical listening in automobiles might require a more detailed training regimen and additional repeats within a trial [6]. A modified training program was used to train and evaluate subjects for automobile listening tests. The listener's repeatability was then studied when using a PC-based preference testing program and when listening in-situ. Criteria were established for determining listeners' accuracy in resonance detection, their proper application of that ability in a preference testing program, and for the number of listening repeats required for statistically significant ratings.
