41-55 dB Moderate hearing loss, difficulty hearing conversational speech.
56-70 dB Moderately-severe hearing loss, great difficulty hearing speech in both quiet and noisy environments.
71-90 dB Severe hearing loss, cannot hear most environmental sounds or normal speech without the use of hearing aids or assistive listening devices.
91 + dB Profound hearing loss, this is what most people think of as “deaf.” Cannot hear environmental sounds or speech.
