“…A number of studies have shown that hearing loss among diabetics predominantly involves the high frequencies. 7,8 This is similar to presbyacusis, that affects higher frequencies first. 9,10 Sensory hair cell loss and cochlea neuron loss at the basal turns are thought to be responsible for presbyacusis.…”

Background: The typical hearing loss described among diabetes patients is progressive, bilateral, sensorineural deafness of gradual onset that predominantly affects the higher frequencies. Although there is mounting evidence for a relationship between diabetes and hearing impairment the awareness of auditory organ involvement in the course of diabetes is still not widespread among healthcare providers involved in diabetes care. Objective of present study was to assess the prevalence and the factors influencing sensorineural deafness among the patients with type II diabetes mellitus.Methods: A cross-sectional study was conducted at our hospital for a period of 6 months. All type II diabetes patients without any other major systemic illness (CVA, coronary artery disease, thyroid disorders) were included for the study. A total of 300 patients were included in our study and the informed consent was obtained from all the study participants. A detailed history related to hearing loss and diabetes status was elicited from all the patients. All basic blood investigations along with HbA1c was performed on all the patients. All the patients were subjected to pure tone audiometry and it was performed using a pure tone audiometer model AUL 12096 audiometer of Labat company in a sound proof room.Results: The total prevalence of sensori-neural deafness among the study subjects was found to be 51.3% with majority of them having mild to moderate degree of sensori-neural deafness. Increase in age, female gender, longer duration of diabetes and higher HbA1C levels are the factors which had influenced the state of sensorineural deafness among the study subjects.Conclusions: The use of audiological test at primary care level should be made mandate for screening all the diabetes patients for hearing loss such a way the quality of life can be improved for patients requiring therapeutic interventions for their hearing improvement.

“…It has been found that speech recognition performance of older adults even with normal hearing, especially in presence of noise, is reduced to greater extent in older adults than compared to young adults. It happens probably due to greater auditory temporal processing deficits (Mattys et al, 2012;Pichora-Fuller & Souza, 2003;Gordon-Salant, 2005;Pichora-Fuller & Singh, 2006). Other factors such as widening of auditory filters also may lead to worsened speech perception with presbycusis (Saremi and Stenfelt, 2013).…”

Exploring Cognitive Spare Capacity : Executive Processing of Degraded Speech

Cognitive resources, specifically working memory capacity are used for listening to speech, especially in noise. Cognitive resources are limited, and if listeners allocate a greater share of these resources to recovering the input signal in noise, fewer resources are available for interpreting and encoding its linguistic content. Although the importance of CSC for individual success in communicative situations has been acknowledged, this concept has not hitherto been explored experimentally. In this thesis, a CSC test (CSCT) was developed and administered to young adults with normal hearing and older adults with age-related hearing loss. CSCT required executive processing of speech at different memory loads with and without visual cues in different noise conditions. A free recall task using the same material was administered for comparison purposes and a battery of cognitive tests was administered to understand the relation between CSC and established cognitive concepts. The aims of the thesis were to investigate how CSC is influenced by 1) different executive demands and memory loads; 2) background noise; 3) visual cues; 4) aging and concomitant hearing loss. The results showed that 1) CSC was sensitive to memory load, and updating demands reduced CSC more than inhibition demands; 2) CSC was reduced in background noise compared to quiet; 3) visual cues enhanced CSC especially in noise; 4) CSC was reduced with ageing and concomitant hearing loss especially when visual cues were absent, memory demands were increased and background noise was speech-like. The main finding of this thesis was that visual cues enhanced CSC for older individuals with hearing loss, specifically in adverse listening conditions. This demonstrates the importance of audiovisual testing in audiological assessment. Further, specific cognitive resources depleted during listening in noise were at least partially compensated by other cognitive functions. This thesis is the first step towards a theoretical understanding of CSC and in future, tests of CSC may play a crucial role in planning rehabilitation of persons with hearing loss.

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...
