Document Summary
Hearing loss and the audiogram, continued 2. 10 db hl to 20 db hl: mild. 20 - 40 db hl: moderate 40 - 55 db hl, moderately - 26 to 40 db: moderate hearing loss. 41 to 55 db: moderately severe loss. 91 to 120 db: deaf above 120 db. 2 frequency pta: best 2 off 500, 1000, and 2000 hz (sloping losses) The configuration or shape of the hearing loss refers to the extent of hearing loss at each frequency and the overall picture of hearing that is created. For example, a hearing loss that only affects the high frequencies would be described as a high-frequency loss. Its configuration would show good hearing in the low frequencies and poor hearing in the high frequencies. On the other hand, if only the low frequencies are affected, the configuration would show poorer hearing for low tones and better hearing for high tones.
