The Different Degrees of Hearing Loss - Chart
Hearing loss differs among individuals. You can either visit an audiologist for a hearing test or take one online.
The results may classify your hearing as "mild," "moderate," or "severe" based on the volume of sounds you can hear, measured in Decibels (dB).
Here's a chart of the hearing loss scale from the 2021 World Health Organization Hearing Report:
| Degree of Hearing Loss | Hearing loss range in dB | Effect on Hearing |
| Normal Hearing | <20 dB | No problems hearing |
| Mild Hearing Loss | 20 - 35 dB | Almost no problems hearing |
| Moderate Hearing Loss | 35 - 50 dB | Cannot hear conversations clearly |
| Moderate to Severe Hearing Loss | 50 - 65 dB | Conversations are difficult, must use a loud voice to communicate |
| Severe Hearing Loss | 65 - 80 dB | Can't hear most of the conversation, even when using loud voices |
| Profound Hearing Loss | 80 - 95 dB | Extreme difficulty hearing sounds |
| Total Hearing Loss / Total Deafness | >95 dB | Cannot hear speech and most environmental sounds |
| Unilateral Deafness / Single Sided Deafness | Good ear < 20dB, Bad ear > 35dB | May have difficulty locating the sound source / direction |
