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...

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,...

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...

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)...

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...

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...

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...

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...

Exposure to organic solvents has been shown to be ototoxic in animals and there is evidence that these solvents can induce hearing loss in humans. In this study, the effects of inhalation of the possibly ototoxic solvent ethyl benzene on the cochlear function and morphology were evaluated using three complementary techniques: (1) reflex...

Rats were exposed to ethyl benzene at 0, 300, 400 and 550 ppm for 8 hours/day for 5 consecutive days. Three to six weeks after the exposure, auditory function was tested by measuring compound action potentials (CAP) in the frequency range of 1-24 kHz and 2f1-f2 distortion product otoacoustic emissions (DPOAEs) in the frequency range of 4-22.6...

A laboratory model of the wireless "Communications EarPlug" (w-CEP) was developed. Standard communication earplugs (using wires) are known to offer relatively good intelligibility of intercom speech at high ambient noise levels. The intercom sound is produced by means of a commercially available miniature transducer, integrated in the earplug....

Health technology assessment (HTA) consists of the systematic study of the consequences of the introduction or continued use of the technology in a particular context, with the explicit objective to arrive at a judgment of the value or merit of the technology. Ideally, it is aimed at assessing all aspects of a given technology or group of...

Exposure to noise constitutes a health risk. There is sufficient scientific evidence that noise exposure can induce hearing impairment, hypertension and ischemic heart disease, annoyance, sleep disturbance, and decreased school performance. For other effects such as changes in the immune system and birth defects, the evidence is limited. Most...

The Youth Health Care guideline 'Early screening for hearing impairment, ages 0-19 years' draws the attention of all parties involved to the case finding of, notably, perceptive hearing loss; it helps workers in the Youth Health Care argue their referrals and improve the next steps in the process. Referrals always aim at ruling out perceptive...
