audiogram demo

hearDeLight offers three methods for inputting audiogram data:

1. measurement

2. manual entry

3. selection from standard audiograms

Users can view the input audiogram, displayed in red for the left ear and blue for the right ear.

This audiogram serves as the basis for hearDeLight to calculate amplifier gain values for both ears across different frequencies and input intensity levels.

amplifier gain right

As input intensity increases from 50 to 90 dBSPL, the amplifier gain gradually decreases.
