What percentage of hearing loss is considered severe?
Mild hearing loss: Hearing loss of 20 to 40 decibels. Moderate hearing loss: Hearing loss of 41 to 60 decibels. Severe hearing loss: Hearing loss of 61 to 80 decibels. Profound hearing loss or deafness: Hearing loss of more than 81 decibels.What level of hearing loss is considered deaf?
If you are unable to detect sounds quieter than 90dB HL (decibels Hearing Level), it is considered a profound hearing loss for those frequencies. If the average of the frequencies at 500Hz, 1000Hz, and 2000Hz is 90dB or higher, the person is considered deaf.
