“…Research has shown that as people age deterioration occurs on many fronts; hearing sensitivity declines, dynamic range is reduced, speech understanding in noise is compromised, and cognitive processing slows, to name just a few. Effective communication in complex listening environments requires the peripheral auditory systems, central auditory pathways, and cognitive systems to all function effectively (Schneider, Pichora-Fuller, & Daneman, 2010). If the process is impeded at any one point, then the ability to understand speech breaks down (Schneider et al, 2010).…”

Difficulty understanding speech in background noise, even with amplification to restore audibility, is a common problem for hearing-impaired individuals and is especially frequent in older adults. Despite the debilitating nature of the problem the cause is not yet completely clear. This review considers the role of spatial processing ability in understanding speech in noise, highlights the potential impact of disordered spatial processing, and attempts to establish if aging leads to reduced spatial processing ability. Evidence supporting and opposing the hypothesis that spatial processing is disordered among the aging population is presented. With a few notable exceptions, spatial processing ability was shown to be reduced in an older population in comparison to young adults, leading to poorer speech understanding in noise. However, it is argued that to conclude aging negatively effects spatial processing ability may be oversimplified or even premature given potentially confounding factors such as cognitive ability and hearing impairment. Further research is required to determine the effect of aging and hearing impairment on spatial processing and to investigate possible remediation options for spatial processing disorder.

“…Age-related HL, the focus of this thesis, originates with the deterioration of auditory function and is part of normal aging, usually starting in the middle adulthood (Pearson et al, 1995;Schneider, Pichora-Fuller, & Daneman, 2010). Outer hair-cell damage, degeneration of the stria vascularis (producing endocochlear potential) and the auditory nerve are the main causes (Pichora- Fuller & Singh, 2006), and auditory processes, such as temporal resolution and duration discrimination, are negatively affected (Fitzgibbons & Gordon-Salant, 2010;Saremi & Stenfelt, 2013).…”

“…According to Köpke, Deubel, Engeln and Schlag (1999), car availability and car use are related to positive self-perception in older people, and research suggests driving cessation may be a risk factor for a depressive development (Fonda, Wallace, & Herzog 2001;Marottoli et al, 1997). With agerelated HL being the most common type of HL (Pearson et al, 1995;Schneider, Pichora-Fuller, & Daneman, 2010) and with increasing travel habits among older adults (and the gap between actual mobility and desirable mobility), it is important to understand the effect of HL on mobility.…”

“…This is the most common type of HL typically starting around middle adulthood and progressing, affecting the high frequency ranges particularly (Pearson et al, 1995;Schneider, Pichora-Fuller, & Daneman, 2010) and inducing distortion (Moore, 1995). The prevalence of age-related HL in Europe is roughly 30% for men and 20% for women at the age of 70 years, and 55% for men and 45% for women at the age of 80 years (Roth, Hanebuth, & Probst, 2001).…”

Effects of hearing loss on traffic safety and mobility

Research into the effect of hearing loss (HL) on traffic safety and mobility is limited and the empirical findings are somewhat inconsistent. HL is one of the most frequent sensory deficits in humans, leading to loss of auditory information, which may affect behavior in traffic situations and might reduce traffic safety and mobility. The prevalence of age-related HL in Europe is roughly 30% for men and 20% for women at the age of 70 years, and 55% for men and 45% for women at the age of 80 years. The prevalence of age-related HL is increasing, and as a consequence the number of road users with HL will also increase.The aim of this PhD thesis was to investigate traffic safety and mobility for individuals with HL. Three studies were conducted: 1. a questionnaire survey aimed to evaluate differences in choice of transportation that might be related to HL, 2. a driving simulator study that looked into compensatory strategies and evaluated the efficiency of a tactile signal to alert the driver, and 3. a field study to evaluate these effects in real traffic and to evaluate a navigation system with a supportive tactile signal.The results of the three studies indicate that there are effects of HL on traffic safety and mobility. The effects are relatively small and often bound to driving complexity; but, systematic and consistent in replicated studies. Differences in transportation habits related to HL include less likelihood of having a driver's license and a higher valuing of written information, with the latter possibly prioritized before time and safety issues. Moreover, respondents with more HL were less concerned about the effects of HL, which suggests that they might be using compensatory strategies.In the experimental studies, differences in driving behavior related to HL were bound to driving conditions and occurred when the complexity of the driving task increased. There was also an effect of HL on visual behavior, indicated in the simulator and confirmed in the field study, suggesting that drivers with HL have more active visual behaviors with more frequent glances in the rear-view mirror and a general scanning of the environment before looking away from the road. A tactile signal in the driver seat was found useful in both experimental studies, both for calling for the driver's attention and facilitating navigation using a GPS navigation device.It was concluded that there are effects of HL on both traffic safety and mobility, consistently pointing toward a generally more cautious driving behavior with the use of both compensatory and coping strategies, which suggests a difference in experienced safety. Compensatory strategies associated with HL include driving at lower speeds and using a more comprehensive visual search behavior. Coping strategies associated with HL include engaging less in distracting activities. Evaluation of the tactile signal suggests that it may make driver assistance systems more accessible, not only to drivers with HL, but to all drivers. At the same time, the systems might bec...

“…In other words, to acquire and use the information contained in spoken language requires the smooth and rapid functioning of an integrated system of perceptual and cognitive processes. Recent evidence suggests that the operation of this integrated system is more easily disrupted in older than in younger adults, especially when there are competing sounds in the auditory scene (see Schneider et al, 2010;Wingfield & Tun, 2007). In turn, the increased susceptibility to disruption of language processes in older adults by competing sound sources not only leads to speech understanding difficulties, but also can negatively impact those cognitive processes that make it possible to comprehend 1 and remember what was heard.…”

How Age Affects Auditory--Cognitive Interactions in Speech Comprehension

To participate effectively in multi-talker conversations, listeners need to do more than simply recognize and repeat speech. They have to keep track of who said what, extract the meaning of each utterance, store it in memory for future use, integrate the incoming information with what each conversational participant has said in the past, and draw on the listener's own knowledge of the topic under consideration to extract general themes and formulate responses. In other words, to acquire and use the information contained in spoken language requires the smooth and rapid functioning of an integrated system of perceptual and cognitive processes. Here we review evidence indicating that the operation of this integrated system of perceptual and cognitive processes is more easily disrupted in older than in younger adults, especially when there are competing sounds in the auditory scene.
