Question

write about the characteristics of sound

Answer 1

Sound waves are often simplified to a description in terms of sinusoidal plane waves, which are characterized by these generic properties:Frequency, or its inverse, wavelength.
Amplitude, sound pressure or Intensity.
Speed of sound.Direction.

Answer 2

In physics, sound is a vibration that typically propagates as an audible wave of pressure, through a transmission medium such as a gas, liquid or solid.

In human physiology and psychology, sound is the reception of such waves and theirperception by the brain.[1] Humans can hear sound waves with frequencies between about 20 Hz and 20 kHz. Sound above 20 kHz isultrasound and below 20 Hz is infrasound. Other animals have different hearing r

Sound is defined as "(a) Oscillation in pressure, stress, particle displacement, particle velocity, etc., propagated in a medium with internal forces (e.g., elastic or viscous), or the superposition of such propagated oscillation. (b) Auditory sensation evoked by the oscillation described in (a). "[4] Sound can be viewed as a wave motion in air or other elastic media. In this case, sound is a stimulus. Sound can also be viewed as an excitation of the hearing mechanism that results in the perception of sound. In this case, sound is a sensation.
