Although sound travels quite fast, it is still possible to calculate its speed in air. To do this, the time it takes a sound to travel a measured distance must be recorded. Either the distance ...

The AMPLITUDE of these pressure variations (that is, their maximum displacement from the ambient atmospheric pressure) is called the sound pressure variation, whereas the effective pressure variation ...

A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and scientists record and analyse sounds using wave traces. Sometimes you can see the source of the sound ...

What is common to all sound is a pattern of change over time called an oscillation or vibration ... the diagram below also shows an oscillation - with its continuous variations in amplitude regarded ...

A tuning fork being struck can provide an example of the pressure fluctuations in the air and how the air particles oscillate (move in one direction rhythmically) when we perceive sound. Analysing the ...

Both these terms are associated with sound. Sound is usually measured in the terms of frequency and amplitude. Amplitude refers to the loudness, whereas, frequency refers to the pitch or sharpness.

Sound vibrations leave the singer's mouth ... This additional height, or amplitude, indicates that the signal has more power. Notice, too, that the frequency of the incoming and outgoing signals ...
