what are the different characteristics of sound ? define them
Answers
hey,
here is ur answer..
A sound can be characterized by the following three quantities:
(i) Pitch.
(ii) Quality.
(iii) Loudness.
Pitch is the frequency of a sound as perceived by human ear. A high frequency gives rise to a high pitch note and a low frequency produces a low pitch note. Figure 2 shows the frequencies of same common sounds.
A pure tone is the sound of only one frequency, such as that given by a tuning fork or electronic signal generator.
The fundamental note has the greatest amplitude and is heard predominantly because it has a larger intensity. The other frequencies such as 2fo, 3fo, 4fo, ............. are called overtones or harmonics and they determine the quality of the sound.
Loudness is a physiological sensation. It depends mainly on sound pressure but also on the spectrum of the harmonics and the physical duration.
