Audio Quality Evaluation System Frequently Asked Questions
Question number FAQ-1086
The sound of a door closing is a transient phenomenon with a duration of around 200 ms, and it raises the question of whether sound quality evaluation metrics such as loudness and sharpness can be applied.
Loudness can vary even at the same sound level depending on whether it is steady or transient. Our sound quality analysis method can also analyze transient sounds (specifically incorporating the temporal masking effect), with parameters calculated in as little as 20 ms. Sharpness is similar.
