How do I read my hearing test results?
The results of the hearing test are an indication for the degrees of hearing loss:
- Normal hearing: -10 to 20 dB.
- Mild hearing loss: 20 to 40 dB higher than normal.
- Moderate hearing loss: 40 to 70 dB higher than normal.
- Severe hearing loss: 70 to 90 dB higher than normal.
- Profound loss: 90 dB or more.
How long does an audiogram take?
The audiologist will then want to test your hearing by performing an audiogram. The test will take about 20-30 minutes. You will be played a series of sounds through headphones and be asked to respond in some way that you have heard the sound normally by pressing a button every time no matter how quiet or faint.
How is Audia PTA calculated?
Hearing sensitivity within the speech frequencies is known as the pure-tone average (PTA) and can be calculated by adding the thresholds obtained at 500, 1000, and 2000Hz and dividing the result by 3. For audiometric results to be valid, the patient must respond to stimulation of the ear being tested.
Is it bad to fail a hearing test?

What does DBHL mean?
decibels Hearing Level
Clinicians measure sound intensity in dB HL (decibels Hearing Level), i.e. dB relative to the quietest sounds that a young healthy individual ought to be able to hear.
What are the 2 axes in an audiogram?
Axes on Audiogram Audiograms have two axes. The horizontal axis (x-axis) represents frequency, which is measured in hertz (Hz) and is ordered lowest to highest, like keys on a piano. The lowest frequency that appears is typically 250 Hz, while the highest is 8000 Hz. This range encompasses most speech frequencies.
What is an audiogram and how does it work?
The audiogram is a chart that shows the results of a hearing test. It shows how well you hear sounds in terms of frequency (high-pitched sounds versus low-pitched sounds) and intensity, or loudness. The audiogram shows results for each ear and tells the audiologist the softest sound you can hear at each specific frequency.
What does audiogram mean?
Definition of audiogram. : a graphic representation of the relation of vibration frequency and the minimum sound intensity for hearing.
What is an audiogram says about your hearing loss?
An audiogram is a graph that shows the softest sounds a person can hear at different pitches or frequencies . Asymmetrical hearing loss is when each ear has a different level or type of hearing loss. Each ear is represented by a different line on the graph. If your graphs or lines look different, you have asymmetrical hearing loss.
How is an audiogram read?
How to read an audiogram Looking at the audiogram graph, you will see two axes: The horizontal axis (x-axis) represents frequency (pitch) from lowest to highest. The lowest frequency tested is usually 250 Hertz (Hz), and the highest is usually 8000 Hz .
