Hearing loss is ranked in several levels.  These levels can help choose which hearing aid is right for you.

The severity of a hearing impairment is ranked according to the additional intensity above a nominal threshold that a sound must be before being detected by an individual; it is measured in decibels of hearing loss, or dB HL. Hearing impairment may be ranked as mild, moderate, moderately severe, severe or profound as defined below:

 

Mild:

for adults: between 26 and 40 dB HL

for children: between 20 and 40 dB HL

Moderate: between 41 and 55 dB HL

Moderately severe: between 56 and 70 dB HL

Severe: between 71 and 90 dB HL
