Degree of Hearing Loss

The audiologist is looking for quantitative information with regard to your degree of hearing loss.

Hearing levels are expressed in decibels (dB):

  • normal hearing (0 to 20 dB HL)
  • mild hearing loss (20–40 dB HL)
  • moderate hearing loss (40–60 dB HL)
  • severe (60–80 dB HL) and profound hearing loss (80 dB HL or greater)
