The patient’s thresholds at each frequency are recorded on an audiogram, which is usually shown as a graph. Many audiologists record the information for both ears on the same audiogram form, whereas others use a separate graph for each ear. The various levels of hearing loss are shown by the patient’s audiogram results. Audiologists can use this test to determine the type and severity of hearing loss.
How Does an Audiogram Work?
An audiologist assesses your hearing ability through a pure tone audiometry test. This is how the process works:
- The patient should be seated in a comfortable chair
- The patient will wear the headphones given by the audiologist
- The audiologist will give instructions
- Some different sound will be noticed by the patient
- The patient will tell when they hear any sound by raising their hand or pressing a button

Reading an Audiogram
A pure tone audiogram is a graphical representation of the results from pure tone audiometry displayed in level (dB HL) as a function of frequency (Hz). Horizontal Axis represents Frequencies (125 Hz to 8000 Hz) and Vertical Axis represents Threshold level (-10dB to 120 dB).
Symbols such as “O” and “X” are used to mark the air conduction thresholds for the right and left ears, respectively.
Example of audiogram
The results are categorized as:
| Degree of Hearing Loss | Hearing Threshold (dB HL) |
| Normal Hearing | 0 to 25 dB |
| Mild Hearing Loss | 26 to 40 dB |
| Moderate Hearing Loss | 41 to 55 dB |
| Moderately Severe Hearing Loss | 56 to 70 dB |
| Severe Hearing Loss | 71 to 90 dB |
| Profound Hearing Loss | 91 dB or more |
Why Is an Audiogram Important?
An audiogram is important for:
- Detecting early signs of hearing loss
- Differentiating between conductive and sensorineural hearing loss
- Monitoring changes in hearing over time
- Fitting hearing aids or cochlear implants
- Assessing hearing in work environments with noise exposure
Who Should Get an Audiogram?
A hearing test can help anyone; however, it is particularly advised for:
- People who are older than fifty
- People who frequently spend time in noisy places
- Children whose speech development is delayed
- People who have tinnitus, or ringing in the ears
- Individuals who have trouble following conversations, particularly in noisy environments
Conclusion
An audiogram test is a simple and very effective method of evaluating your hearing health. The test provides information about the health of your ears, regardless of whether you’re having hearing problems or want a proper checkup. Early detection of hearing problems gives better outcomes and more effective treatment plans in advance. Book a free hearing test today and take the first step towards healthy hearing.
