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.

Characteristics of Sound
There are three characteristics of sound.
1.Loudness
2.Pitch
3.Quality/timbre
Loudness
It is the characteristic of the sound by which a loud sound can be distinguished from a soft sound. Loudness depends on the intensity of sound near the ear. It is the measure of ear's response to the vibration.
Pitch
Pitch of a sound depends upon the frequency of the sound recorded by the human. If the frequency of a vibrating object is low then the pitch of sound is said to be low and vice versa
Quality/Tibre
It is that characteristic if sound which enables us to distinguish between the sounds if same loudness and pitch. Quality of a sound depends on wave form of the sound.
