characteristic of highness or lowness of a sound is called The frequency of a sound wave determines the pitch of the sound you hear. Remember that frequency is the number of waves passing a fixed point in a given period of time. A high-frequency wave with short wave-lengths, such as that produced by a tiny flute, makes a high-pitched sound.
Pitch is determined by the frequency of a wave, and frequency is the combination of wavelength and speed at which the wave is traveling. Sound has a constant speed of 343 meters per second, so wavelength dictates pitch. The longer a sound's wavelength, the lower the pitch of that sound. Full Answer >.
