On the other hand, because recorded thresholds in sound-field audiometry indicate the acuity of the better-hearing ear, if a ., < 15 dB HL), it is better to move to another frequency or stimulus to map out a greater portion of the audiogram. The lower this number, the lower the pitch.[1] It becomes noticeable around age 60 and progresses slowly; however, there is evidence that certain stressors can speed the rate of deterioration.
