Purpose: The significance of extended high-frequency (EHF) hearing (> 8 kHz) is not well understood so far. In this study, we aimed to understand the relationship between EHF hearing loss (EHFHL) and speech perception in noise (SPIN) and the associated physiological signatures using the speech-evoked frequency-following response (sFFR). Method:…

Purpose: Alterations in primary auditory functioning have been reported in patients with Parkinson's disease (PD). Despite the current findings, the pathophysiological mechanisms underlying these alterations remain unclear, and the effect of dopaminergic medication on auditory functioning in PD has been explored insufficiently. Therefore, this…

Increased life expectancy in persons with Down syndrome (DS) is associated with premature age-related changes. The aim of this study was to assess auditory function in adults with DS and to evaluate the prevalence of hearing loss in this population. Audiometric tests were performed in 72 adults with DS (mean age 37.3 ± 10.1 years, 51.4% females).…

Audiologic test results were reviewed for 30 patients whose hearing was preserved following eighth nerve tumor surgery. Improved auditory brainstem response tracings were seen as probably indicating increased neural synchrony due to reduced pressure on the cochlear nerve following surgery, whereas reduced hearing sensitivity probably reflects…

Measured how well elderly persons hear in everyday auditory communication situations. Results of the new Speech-In Noise (SIN) test were better predictors of hearing communication performance than any of the traditional audiometric measures. Because the SIN test is so brief, it is ideal for mass screening of hearing among the elderly. (Author/ABB)

The study employed measures of frequency resolution obtained from individual subjects (two normal and three with sensorineural hearing loss) to predict each subject's vowel recognition performance. A relation between impairments of frequency resolution and vowel recognition was found. The described model may be useful in predicting vowel…

Puretone auditory assessment of 21 adults with severe to profound mental retardation indicated that a bivariate plotting procedure of predicting hearing sensitivity from the acoustic reflexes should be included in an audiological test battery for this population. (CL)

The feasibility of operant audiometry was investigated with six normal, six hearing impaired, six severely retarded, and six multihandicapped (deaf-blind) children. The operant procedures allowed the unilateral testing of some Ss under earphones who could not be tested using conventional audiometric methods. (Author/SEW)

Although many distortion-product otoacoustic emissions (DPOAEs) may be measured in the ear canal in response to 2 pure tone stimuli, the majority of clinical studies have focused exclusively on the DPOAE at the frequency 2f1-f2. This study investigated another DPOAE, 2f2-f1, in an attempt to determine the following: (a) the optimal stimulus…

A model for identification of hearing impairment which combined tympanometry and the puretone procedures outlined by the American Speech and Hearing Association was tested with 8,528 elementary age children from six Connecticut towns. The nine goals of the project included obtaining pass/fail ratios for puretone audiometry within minus 1 percent…

Six papers contributed by graduate students report on studies that focused on the application of theory to practice in speech-language pathology and audiology. The first study revealed the ability of an autistic child to adapt to conversational partners of various ages and linguistic abilities. In the second paper, a language impaired child's…
