Acoustic Phenomena

Notes

Pressure Amplitude and Musical Sound

The branch of physics that deals with the process of the production, transmission and reception of sound is called acoustics. This note provides us an information on acoustic phenomena.

Characteristics of Musical Sound and Intensity of Sound

The pitch is a sensation experienced by a listener. This note provides us an information on characteristics of musical sound and intensity of sound.

Beats

The periodic variation in the intensity of sound at a point, due to the superposition of two sound waves of slightly different frequencies travelling in the same direction, is called beats. This note provides us an information on beats.

Doppler Effect and It's Cases

The apparent change in frequency of sound wave due to the relative motion of source of sound of sound and observer is called Doppler’s effect. This note provides us an information on Doppler's effect and its causes.

Doppler Effect, Waves and Noise Pollution

If the medium travels to the direction of a sound wave then a frequency of sound increases and if medium travels in opposite direction of a sound wave then the frequency of sound decreases. This note provides us an information on doppler effect waves and noise pollution.
