An audiogram is the product of a hearing test. More precisely, it's a graphical representation on paper, showing the specific pitches (frequencies) and loudness (intensity) levels that a person can hear with each ear.

1. You listen to a series of pure tones (simple sounds) using headphones or with tiny soft inserts in each ear. The tones range from 250 Hz through 8000 Hz (frequencies most relevant to hearing everyday environmental and speech sounds)
   
   
2. You indicate  - either by raising a hand or pressing a response button - whether or not you actually heard the sound
   
   
3. The sounds begin to decrease in intensity (loudness) so that the hearing care professional can determine where it starts to become difficult for you to hear (your hearing threshold)
   
   
4. The thresholds are recorded on the audiogram with frequency, intensity and ear-specific information in dB HL
