Quality is the right answer. Quality/Timber helps us to identify someone by his voice while sitting in dark room.


» Quality can be used to differentiate between two sounds having even the same pitch and same loudness. It is also known as timber.

» Pitch :- It is directly proportional to the frequency of the sound. The higher is the frequency, the higher is the pitch.
