“…Ear canal collapse may explain the high frequency conductive hearing loss found in some studies (Glorig & Davis, 1961;Nixon, Glorig, & High, 1962;Rosen Plester, El-mofty, & Rosen, 1964) which was especially pronounced by age 80. Sataloff, Vassallo, & Menduke (1965), however, did not find this high frequency conductive hearing loss in their elderly subjects. Because ear canal collapse was not considered in some of the early data, present norms may be inaccurate, especially for the higher frequencies in older listeners.…”

Many aspects of auditory processing in aging listeners are poorly understood. Methodological problems encountered with the aging population, ranging from ear canal collapse to a conservative criterion, have rarely been considered in past research. The relation between pure-tone thresholds and other aspects of auditory functions is unclear. There have been few studies of frequency and temporal analysis in aging listeners. There is disagreement on the effect of age on speech discrimination abilities in various listening conditions, and the cause of speech perception problems in aging listeners has not been adequately investigated. Areas of importance for clinical consideration and auditory research with aging listeners are discussed.

“…An experimental analysis in human temporal bones (TBs) showed a trend of decreased sound transmission in the middle ear at higher frequencies (>3 kHz) with age [7]. However, others could not confirm these findings [8][9][10][11][12].…”

A retrospective analysis to quantify age-related changes of the incudo-malleolar joint (IMJ) and incudo-stapedial joint (ISJ), and to analyse changes in the air-bone gap (ABG) with age, was performed. Defined histologic parameters of 153 IMJ and 106 ISJ from subjects aged from birth to 70 years were correlated to age. Additionally, audiograms of 1760 ears of 974 other subjects aged 20 to 80 years were retrospectively analysed and the ABG was correlated to age. The joint space (age group from 0 to 10 compared to 61 to 70 years) became significantly wider with age (IMJ: from a mean of 44 µm to 100 µm, p < 0.001; ISJ: from a mean of 28 µm to 69 µm, p < 0.009. The thickness of cartilage of the incus decreased in the first 20 years of life (IMJ, from a mean of 88 µm to 65 µm, p < 0.01; ISJ: from a mean of 44 µm to 35 µm, p < 0.01). The ABGs of younger ears (20–40 years) was significantly larger at 500 Hz compared to older ears (60–80 years) by 2–4 dB, while it was significantly smaller by 3–5 dB at 4000 Hz (p < 0.0017). Interindividual variations in all age groups were large for both analyses. The increased joint spaces could potentially reduce the stiffness in the joints and explain the increase in ABG at 4000 Hz and the drop at 500 Hz. While the average change is small and of minimal clinical relevance, a larger increase of ABG with age is seen in some subjects.
