The evaluation method of door closing sound quality based on time-frequency characteristics of A-weighted sound pressure level is presented with its virtues and defects pointed out. The computing models for Zwicker instantaneous loudness and time-varying loudness, Moore instantaneous loudness and time-varying loudness as well as sharpness are then built and their applicability to door closing sound quality evaluation is analyzed. Finally, a sound quality evaluation method for automotive door closing noise with the time-frequency characteristics of A-weighted sound pressure level, instantaneous loudness and sharpness as indicators is established and applied to the evaluation on two vehicle closing noise samples, and hence its feasibility is verified.
