The human ear can hear frequencies (pitches of sound) at 20 – 20,000 Hertz, but the range where the most useful pitches, such as speech sounds, occur is at 500-4000 Hz. A hearing test measures how well a person hears at 250 – 8000 Hz. Hearing loss from noise exposure typically affects the high frequency range of human hearing (3000-6000 Hz).

The most common pattern of hearing loss in older adults is presbycusis, a bilateral high frequency sensorineural hearing loss that occurs with advancing age. Pure- tone threshold sensitivity diminishes with age; those under 55 years typically lose hearing at a rate of 3 dB per decade, and those over 55 at a rate of 9 dB per decade.[1]

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.
