Human Hearing and Subjective Response to Sound
Published in Malcolm J. Crocker, A. John Price, Noise and Noise Control, 2018
Malcolm J. Crocker, A. John Price
Presbycusis is believed to be caused by central nervous system deterioration with aging, in addition to changes in the hearing mechanism in the inner ear.4'45 Hinchcliffe47 believes that these changes explain the features normally found in presbycusis: loss of discrimination of normal or distorted speech, increase in susceptibility to masking particularly by low frequency noise, and a general loss in sensitivity. Rosen48 has suggested that degenerative arterial disease is a major cause of presbycusis.
Age-Related Physiological Changes Influencing Work Ability

Age-associated hearing loss (presbycusis) affects men more often than women and is intensified in exposure to higher frequency sounds. The diseases that become more frequent as people age, further altering their hearing, include, among others, tinnitus (ringing in the ears) or Meniere’s disease. Sensory changes in hearing can severely impact functional abilities of aged persons as well as their communication skills. Fast speech, speech with reverberation and background noise further aggravate hearing deficit.

Park et al. in a study on mice showed that auditory brainstem response thresholds in the mice with NIHL was higher than control group, and their spatial working and recognition memories were lower than the controls.15 The human studies in this regard has been found a relationship only between hearing loss and cognitive function in the elderly and as a process of aging. Lin et al. in a study on 60–69 year-old individuals found that hearing loss in the elderly significantly affected cognitive function.34 Lin et al. in another longitudinal study on the aging population found that hearing loss was independently associated with lower scores in tests of memory and executive function.35 Although both aging and noise exposure cause a somehow similar sensorineural hearing loss, but the mechanism of NIHL is different from presbycusis, and NIHL usually appears in the working age and is much more important if it affects cognitive function, which may lead to lower concentration and higher rate of errors. We couldn’t find any study on humans about the association between NIHL and different domains of cognitive function to compare with the results of the current study.

Worldwide, roughly 16% of adult-onset hearing loss is attributed to damage resulting from exposure to occupational noise, making it second only to presbycusis as the leading cause of deafness.4,5 For LMSE, the occupational hazard to their hearing arises directly from the music that they help to create, and thus the appropriate nomenclature is music-induced hearing injury (MIHI). This encompasses a cluster of symptoms and auditory damage profiles, resulting from exposure to excessive and/or prolonged sound pressure levels. In acute forms, MIHI occurs as very rapid destruction of the vulnerable inner-ear structures following exposure to sound levels above 130 dB. More common chronic forms, however, are acquired from cumulative injury due to exposure to moderate-to-high sound levels over a prolonged period or from multiple incidents.6,7 The reported auditory symptoms of hearing injury include hearing loss, tinnitus, distortion, diplacusis and hyperacusis. Kähäri et al. reported that 74% of 139 rock/jazz musicians surveyed experienced such symptoms.8
Speech intelligibility in different types of audiograms and speech audiometry by using the simulated hearing loss on the speech material with normal hearing people

There are three recognizable audiograms that are common with hearing impaired people [6]: down-sloping with the fall of approximately 5–10 dB per octave which is common with people with presbycusis;substantially down-sloping after frequency of 1 kHz with dominant hearing loss around the 4 kHz which is common with people with the noise-induced hearing loss (NIHL) and“Cookie bite” shaped curve with dominant hearing loss at middle frequencies.
