Through the sense of hearing we are placed into direct, intimate contact with the surrounding world. Musical, vocal, and other sonic impressions flood us constantly. The normal human ear is sensitive to sonic frequencies ranging from about 20 to 20,000 Hertz (1 Hz = 1 cycle/second), although the range varies with age and other individual factors.

Abstract. Older listeners, both with and without hearing loss, often complain of difficulty understanding conversational speech. One reason for such difficulty may be a decreased ability to process the rapid changes in intensity, frequency, or temporal information that serve to differentiate speech sounds.

Formal audiometry provides relatively precise information displayed by frequency and hearing level. A convenient summary of the audiogram is the pure-tone average (PTA) of the cardinal speech frequencies (500, 1000, 2000, 3000 Hz). As the PTA increases, the hearing ability decreases. Normal hearing for speech is observed for people with PTAs of ...

By age 60, the average loss for men at the critical frequencies has now reached 19 dB compared to age 20, almost twice the amount required to identify an STS, but we really wouldn’t want to label that as an STS situation, since the STS should be reserved for “abnormal” hearing loss. Age correction will take care of that potential.
