Audiometer
To measure hearing sensitivity and threshold across different frequencies (pitches) and intensities (volumes)
Application:
It plays sounds through headphones (air conduction) or bone vibrators to detect the type and severity of hearing loss.
Identifying hearing loss: determines the quietest sound a person can hear.
Medical diagnosis: helps differentiate between conductive and sensorineural hearing loss.
Treatment planning: provides data for fitting hearing aids or assessing middle ear function.

Key Components and Functionality:
Pure Tone Generator: Produces specific frequencies (pitches) for testing.
Attenuator: Varies the loudness of the sound, measured in decibels (dBHL).
Components: Includes headphones for air conduction and bone conductors to test cochlear function.
Output: The results are mapped on an audiogram, a graph visualizing the hearing threshold.
