The human range is commonly given as 20 to 20,000 Hz, although there is considerable variation between individuals, especially at high frequencies, and a gradual loss of sensitivity to higher frequencies with age is considered normal. Sensitivity also varies with frequency, as shown by equal-loudness contours. Routine investigation for Methods Hearing was analysed in 126 CF adults using validated questionnaires, a web self-hearing test (0.5 to 4 kHz), tablet (0.25 to 12 kHz) and sound-booth audiometry (0.25 to 12 kHz). A threshold of ≥25 dB hearing loss at ≥1 audiometric frequency was considered abnormal. Hearing loss is a partial or total inability to hear. Hearing loss may be present at birth or acquired at any time afterwards.

If a patient had a severe hearing loss (e.g., baseline behavioral Fig. 6. Mean pre-exposure hearing thresholds … Hearing loss at extended high frequencies (EHF; above 8 kHz) is common in adults 30 years of age and older, 1, 2 but it usually goes undiagnosed because EHF audiometry is typically not part of the routine audiological exam. The prevailing view is that EHFs are not critical to daily listening. Wiley et al (2008) reported on the progression of hearing loss over a 10-year period, based on 2,130 older men and women (age range 49 to 92 years). In the younger groups (ages 50 to 69 years) the greatest changes were seen in the higher frequencies (3 to 8 kHz)in the older groups (ages 70 to 89 years) threshold changes were greatest for lower frequencies (0.5 to 2 kHz).

Sensorineural Hearing Loss. Sensorineural Hearing Loss . However, clinical audiometry, by which hearing loss is diagnosed, is limited at high frequencies to 8 kHz. Evidence suggests there is salient information at extended high frequencies (EHFs; 8 to 20 kHz) that may influence speech intelligibility, but whether that information is used in challenging listening conditions remains unknown. An audiometric notch is present when one or more of the thresholds at 3–4, or 6 kHz exceeds the pure-tone average of the 0.5 and1 kHz thresholds by 15 dB hearing level (HL) or more, and the 8 kHz threshold is at least 5 dB HL lower (better) than the highest threshold in the 3–6 kHz range.
