What are the degrees of hearing loss?

When you get a hearing test done, two pieces of information matter most for deciding how to manage hearing loss: the type of hearing loss and its degree. Degree is measured in decibels (dB) and follows a standard classification scale that helps doctors quantify exactly how much hearing has been affected.

The scale breaks down as follows:

• 0-25 dB — Normal hearing
• 26-40 dB — Mild hearing loss
• 41-55 dB — Moderate hearing loss
• 56-70 dB — Moderately severe hearing loss
• 71-90 dB — Severe hearing loss
• Above 90 dB — Profound hearing loss

This classification isn't just a technical detail; it directly guides treatment decisions. In moderate and moderately severe sensory neural hearing loss, hearing aid is the suitable option. In conductive hearing loss one should try to fix the underlying issue if possible.

In these severe and profound cases, cochlear implant surgery becomes a more suitable option, since it works differently from a hearing aid by directly stimulating the auditory nerve rather than simply amplifying sound. Knowing where your hearing loss falls on this scale, therefore, gives you and your doctor a clear, practical starting point for choosing the right path forward.
