Hearing is a complex ability. We hear at various levels and frequencies. Here are a list of the hearing levels:
Normal (–10 to 15 dB)
~ able to hear sounds of the English language and most sounds within an adequate distance including overhearing conversations.
Slight (16 to 25 dB)
~ able to hear most sounds of the English language, some overhearing of conversations. Best to get their attention before speaking directly to them. Unable to hear whisper or water running from the faucet, birds chirping, or trees rustling. Words like "feather" or "stop" or "sit" or "pop" may be difficult to hear (and understand).
Mild (26 to 40 dB)
~ able to hear some sounds of the English language. Words indicated in the above in slight level and "zoo," "van," "hey," "have," "here," "go," "camp," "cheer," "chase" may be difficult to hear and understand.
Moderate (41 to 55 dB)
~ able to hear a few sounds of the English language. Words indicated in the levels above and "jam," "going," "helping," "her," "eat," "show," "love," and others ending in -ing will be difficult to hear and understand.
Moderately severe (56 to 70 dB)
~ able to hear loud noises like planes and cars, a piano playing, and maybe a lawn mower running. All of the above sounds are difficult to hear and understand along with most of the sounds of the English language.
