Characteristics Of
Sound Waves
![Page 2: Sound Waves ( Loudness and Intensity)](https://reader036.fdocuments.in/reader036/viewer/2022062308/558cd3c2d8b42ad2068b457a/html5/thumbnails/2.jpg)
They differ from one another in three ways, namely :
(a) Loudness or Intensity(b) Pitch
(c) quality

LOUDNESS
and
ITENSITY

Amplitude
• Amplitude is the maximum
displacement from a wave’s
equilibrium position.

Sound Intensity
increases as the amplitude
and area of the vibrating body
increase.

Loudness also depends on the
listener.

Energy is always
carried by sound waves.

Loud sounds have greater
amplitude than soft sounds.

Sound waves travel in all direction.

sound cause by irregular vibration at the source.
