The results of the experiments have no medical value. They are just for demonstration purposes.
AUDIOMETER
The audiometer is used in the medical field to measure the threshold of hearing sounds.
An audio signal generator generates all the frequencies between 20 Hz and 25 kHz. The patient, through a headset, checks the level of sensitivity in his ears.
