   Sammanfattning : Age affects hearing and cognitive abilities. Older people, with and without hearing impairment (HI), exhibit difficulties in hearing speech in noise. LÄS MER

3. 2. Effects of environmental acoustic factors, individual differences and musical training on speech perception in simulated classrooms

   Författare :Douglas MacCutcheon; Robert Ljung; Daniel Västfjäll; Högskolan i Gävle; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; speech in noise; cognition; perception; musical training; spatial listening; virtual classroom environment; bakgrundsljud; kognition; taluppfattning; musikalisk träning; rumsligt lyssnande; virtuella klassrumsmiljöer; Hållbar stadsutveckling; Sustainable Urban Development;

   Sammanfattning : Formal learning takes place primarily through speech perception in classroom environments and is therefore dependent on the listener’s ability to cope with a number of acoustic factors that interfere with the speech signal. As classrooms are inclusive spaces accommodating learners with a broad range of abilities and backgrounds, this research investigated some of the ways in which individual differences in supporting cognitive skills are related to speech perception outcomes in various challenging acoustic environments.

4. 3. Assessing cognitive spare capacity as a measure of listening effort using the Auditory Inference Span Test

   Sammanfattning : Hearing loss has a negative effect on the daily life of 10-15% of the world’s population. One of the most common ways to treat a hearing loss is to fit hearing aids which increases audibility by providing amplification. Hearing aids thus improve speech reception in quiet, but listening in noise is nevertheless often difficult and stressful. LÄS MER

5. 4. Bilateral hearing aids for bilaterally hearing-impaired persons : always the best choice?

   Författare :Susanne Köbler; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :bilateral hearing aids; binaural hearing; speech-in-noise; dichotic tests; binaural masking level difference;

   Sammanfattning : The most logical solution if a person has a hearing impairment on both ears, seems to be bilateral bearing aid amplification in both ears. Numerous studies have shown the advantages of this fitting strategy. However, there were always some individuals not benefiting from bilateral hearing aids; until recently a neglected group of persons. LÄS MER

7. 5. Associations between stress and hearing problems : epidemiological and experimental findings

   Författare :Martin Benka Wallén; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : It is well established that long-term stress without sufficient recovery can induce plastic changes in certain brain regions by suppressing neural growth or by retraction of dendrites 1-4. Many of these effects can be due to a dysregulation of the hypothalamic-pituitary-adrenal (HPA)-axis, which is the principal system controlling systemic stress response. LÄS MER
