Hearling loss is an important health problem in the elderly which sometimes leads to social isolation. In a study with 62 patients, the diagnostic value of four simple tests for screening for hearing loss in general practice was examined. When paying attention to the loudness of the whispering, the whispered voice test can be a valuable test for...

Objective. To determine which age-related disorders lend themselves for screening followed by intervention in general practice. Setting. Department of General Practice Medicine, University of Leiden. Design. Descriptive. Methods. This study concerned eight frequent age-related disorders: auditory and visual disorders, cognitive limitations,...

Two stages for structuring tone sequences have been distinguished by Povel and Essens (1985). In the first, a mental clock segments a sequence into equal time units (clock model); in the second, intervals are specified in terms of subdivisions of these units. The present findings support the clock model in that it predicts human performance...

4-Aminopyridine (4-AP) has a favorable effect on the disability of certain patients with MS. We investigated the effect of 4-AP on neuropsychological performance in 20 MS patients using a randomized, double-blind, placebo- controlled, crossover design. Although there was a trend for improved performance with 4-AP for two of the tests, we could...

Modification of auditory evoked startle responding using prepulse inhibition was used to examine the effects of trichloroethylene (TCE) exposure on auditory thresholds. Rats were exposed by inhalation to 0, 1500, or 3000 ppm TCE for 18 hours per day, 5 days a week for 3 weeks. Auditory thresholds for 5 and 20 kHz tones were measured before...

In a geographically defined population of very preterm and very low birthweight infants (gestational age < 32 weeks and/or birthweight < 1500 g) hearing was evaluated in 890 children by pure-tone audiometry at the age of 5 years. Hearing loss was conductive/unspecified in 123 (13.8%) and sensorineural in 13 (1.5%) children. The prevalence of...

The present paper describes a clinical test for the assessment of speech perception in noise. The test was designed to separate the effects of several relevant monaural and binaural cues. Results show that the performance of individual hearing-impaired listeners deviates significantly from normal for at least 2 of the following aspects: (1)...

Some preliminary results of a research program on the effects of noise traumata on cochlear functioning are given. Measurements reported here include: the latency of the whole-nerve (compound) action potential (AP), the selectivity of frequency-tuning curves (e.g., the Q10-values) measured for the AP (with a forward-masking technique) and for...

An experiment is reported on the effects of cognitive similarity on proactive and retroactive interference (PI, RI) in short term memory. To avoid confounding between cognitive and acoustic similarity, the materials - i.e. words and digits - were matched with respect to vowel pattern. Effects of both PI and RI were found on recall of words,...

In this article the author points out that, in the case of perceptive deafness (sensorineural involvement), hearing loss for understanding of conversational speech cannot be determined by means of pure-tone audiometric testing. Some years ago a survey was performed in The Netherlands, its aim being to provide industrial medical officers with a...
