This online resource looks at the sensitivity of human hearing.

This free online hearing test measures the relative sensitivity of your ears at different frequencies using the audio capabilities of a computer.

It produces equal loudness contours or hearing sensitivity curves—the frequency response of a person’s ears and has been successfully trialled in a classroom situation where each student used their own ear plugs and computers.

The website also has a multimedia tutorial on the operation of the voice and hearing.

It can be used to reinforce the concepts of the particle model of sound and the structure of ears.

Please note the warning and select low decibel ranges for initial sounds, so as to correctly adjust the volume.
