2.4.1 Amplitude and frequency
The properties of noise which are important in the home are:
- Amplitude (loudness measured in decibels)
- Frequency (pitch measured in hertz)
The amount (amplitude) the pressure fluctuates determines the loudness (decibels) of the sound. The frequency of the pressure fluctuations determines the pitch (hertz).
