When you get a hearing test (audiogram), the results are classified by the Hearing Threshold Level (HTL), measured in decibels (dB). This classification helps determine the impact of the loss on daily communication and guides the appropriate treatment, like selecting a hearing aid or instrument.
This table explains what the average hearing threshold level (in dB) means for your ability to hear common sounds.
