Successful hearing aid fittings using high-technology features for elderly patients require consideration of factors beyond results obtained from routine audiologic evaluations. A holistic hearing aid selection, fitting, and evaluation approach that considers patient characteristics from communication, physical, psychological, and social assessment domains(More)
Noise-induced permanent threshold shifts (NIPTS) were computed from retrospective audiometric analyses by subtracting aging effects on hearing sensitivity in sixty-eight patients with bilateral sensorineural hearing loss who reported significant occupational noise exposure histories. There were significant effects of age on NIPTS but no significant gender-(More)
PURPOSE To survey listening habits and attitudes of typical college students who use MP3 players and to investigate possible safety issues related to MP3 player listening. METHOD College students who were frequent MP3 player users (N = 428) filled out a 30-item online survey. Specific areas probed by the present survey included frequency and duration of(More)
The objective of this study was to analyze differences in incidence and epidemiologic risk factors for significant threshold shift (STS) and tinnitus in deployed military personnel diagnosed with mild traumatic brain injury (mTBI) due to either a blast exposure or nonblast head injury. A retrospective longitudinal cohort study of electronic health records(More)
BACKGROUND Many reports have described that individuals with Alzheimer's disease show neural breakdown in the brainstem nuclei, hippocampus and auditory cortex in the temporal lobe of the brain. However, it is still unclear whether auditory skills mediated by these areas differ across individuals with and without Alzheimer's disease and how these auditory(More)
Hearing acuity can be reduced temporarily after exposure to loud noise, and the physiological responses that occur with exercise may enhance this effect. Currently, it is not known whether short-term reductions in hearing acuity after noise exposure and exercise are a result of temporary changes in auditory function. Therefore, the purpose of this(More)
The purpose of the current study was to study auditory processing (monaural closure, monaural separation, binaural integration, and binaural separation) skills in subjects withand withoutAlzheimer’s disease. Ten individuals with Alzheimer’s disease and seven individuals without Alzheimer’s disease participated in central auditory processing tasks (degraded(More)
OBJECTIVE To explore the relationship between distortion product otoacoustic emissions (DPOAEs) and frequency modulation difference limens (FMDLs) in normal-hearing subjects. DESIGN Fifteen normal-hearing adult subjects (age range = 20 to 29 yr; mean age = 21 yr, 6 mo) participated in the study. Each subject met the following criteria: 1) hearing(More)
BACKGROUND Studies related to plasticity and learning-related phenomena have primarily focused on higher-order processes of the auditory system, such as those in the auditory cortex and limited information is available on learning- and plasticity-related processes in the auditory brainstem. DESIGN AND METHOD A clinical electrophysiological test of(More)
