Properties of Sound

Sound travels in the form of waves. All types of sound have the following properties:

Wavelengthcan be described as the distance between any point on the wave and a corresponding point on the next wave’.

Amplitude indicates the height of a sound wave, how loud the sound is. The higher the ‘height’ of the wave, the louder it is. Amplitude also indicates how strong a sound is.

Frequency is the number of times the wavelength occurs in 1 second. Of the sound source vibrates faster, the frequency is higher, and vice versa; for example, if you examine the wave of the strums of a guitar, it will be different from those of the thud on a table. This means the higher the number of vibrations form the sound source, the higher the frequency. In turn, the higher the frequency, the higher the pitch. Frequency is measured in kilohertz (Khz).
