Patient's question:
Only mention severe hearing lossDoctor's answer:
According to the World Health Organization's hearing loss classification standards, normal hearing is between 0 and 25 decibels. Sounds need to reach 26 to 40 decibels to be heard for mild hearing loss, 41 to 55 decibels for moderate hearing loss; 56 to 70 decibels for moderate-severe hearing loss; 71 to 90 decibels for severe hearing loss; and above 91 decibels for profound or total deafness. Your mother's hearing loss is at 85 decibels, which falls under the category of severe hearing loss (71 to 90 decibels).
