Frequency Range
- The range for hearing is 20Hz to 20kHz. In the human ear, the frequency range is between 20 Hertz and 20 kiloHertz. We could also say this as 20-20,000 Hz. This is the normal human hearing range. The human ear hears best at about 3,000 Hz.
- Frequency is limited. The frequency range of human hearing is limited to the values described above. The reason behind this is due to the shape and size of the human ear. It is relatively small, meaning that it can only transfer a certain amount of energy without being damaged.
- Hearing changes due to ageing. People of older age often find it harder to hear sounds with a higher frequency. This may be due to changes in the inner ear, for example the tiny hair cells can be damaged or die.
