Hearing impairment, or hearing loss, occurs when you lose part or all of your ability to hear. Other terms that are used to refer to hearing impairment are deaf and hard of hearing.
Hearing impairments are classified in terms of the severity and type of hearing impairment. The severity of the hearing impairment is categorized based on the minimum sound that can be heard with your better ear. The higher the decibel (dB), the louder the sound.
With mild hearing impairment, the minimum sound that can be heard is between 25 and 40 dB. People at this level cannot hear soft noises and may have trouble following conversations in noisy settings.
With moderate hearing impairment, the minimum sound that can be heard is between 40 and 70 dB. People at this level cannot hear soft or moderately loud noises and may have trouble hearing unless they use a hearing aid.
With severe hearing impairment, the minimum sound that can be heard is between 70 and 95 dB. People at this level are unable to hear most noises and may rely on lip-reading and/or sign language, even with the use of a hearing aid.
With profound hearing impairment, the minimum sound heard is 95 dB and over. People at this level may only hear very loud noises and rely solely on lip-reading and/or sign language. Hearing aids are not effective.
