Grades of hearing loss
WHO (WHO-1997) classifies hearing loss as follows:
-Average hearing loss less than or equal to 25 decibels is considered normal
-Mild hearing loss with a mean hearing loss between 26 and 40 decibels
-Moderate hearing loss between 41 and 60 decibels
-Mean hearing loss between 61 and 80 decibels for severe hearing loss
-Mean hearing loss greater than or equal to 81 decibels is very severe hearing loss
If you don’t have an audiogram, a rough estimate:
-If you have no problems with normal communication, and only occasionally have trouble hearing other people’s conversations, then the average hearing loss is usually no more than 45 decibels.
-The average hearing loss is about 50~55 decibels if you listen to people’s voices, or if you watch TV at a high volume.
-Other people must speak very loudly to hear, then generally speaking, the hearing loss is more than 56 decibels
-If you can only respond to shouting, car horns, or drums, your hearing loss is 71 decibels or more.
-If you can’t sense the sound, you have a hearing loss of 90 decibels or more.
