Audio Quality Evaluation System Frequently Asked Questions

The comparison based on the sound quality evaluation of the "door closing sound" listed in the catalog is fundamentally an example of different vehicle models, where evaluations based on loudness, sharpness, or their temporal variation patterns can be made regarding sounds such as "a heavy sound" or "a light sound".
Whether subtle changes due to production variations can be evaluated is something that cannot be said without actually trying it, but if it seems that the general public (not trained examiners) can perceive it, it is believed that some degree of comparison can be made.
