when do you measure at inter octave levels | when there is a 20dB difference in hearing between frequencies |
for an adult, hearing is between 0-25 dBHL so hearing is | Normal |
for an adult, hearing is between 26-40 dBHL so hearing is | mild hearing loss |
for an adult, hearing is between 41-55 dBHL so hearing is | moderate hearing loss |
for an adult, hearing is between 56-70 dBHL so hearing is | moderately severe hearing loss |
for an adult, hearing is between 71-90 dBHL so hearing is | severe hearing loss |
for an adult, hearing is greater than 90 dBHL so hearing is | profound hearing loss |
for a child, hearing is between 0-15 dBHL so hearing is | normal |
for a child, hearing is between 16-20 dBHL so hearing is | slight hearing loss |
for a child, hearing is between 21-40 dBHL so hearing is | mild hearing loss |
for a child, hearing is between 41-55 dBHL so hearing is | moderate hearing loss |
for a child, hearing is between 56-70 dBHL so hearing is | moderately severe hearing loss |
for a child, hearing is between 71-90 dBHL so hearing is | severe hearing loss |
for a child, hearing is greater than 90 dBHL so hearing is | profound hearing loss |
sensory classification | hearing loss is the same by air and bone |
conductive classification | normal hearing by bone, hearing loss by air |
mixed classification | hearing loss by air is worse than loss by bone |
in determining the traditional pure-tone average, the frequencies used are | 500, 1K, 2K |
