The Audiometer was made after performing several experiments with the loudness of sounds and how humans hear things.
The meter he made is a way of measuring how well someone can hear compared to what an average person can hear.
Like Feet and Meters are used for measuring the length of objects or the distance between objects, the measurement called a Bell was named to measure the loudness of sounds that humans hear.
More commonly the measurement is called a 'Deci Bell' abbreviated dB which is 1/10th of a Bell.
