1. 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
2. Speech masking speech in everyday communication : The role of inhibitory control and working memory capacity
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. Communication acoustics in classroom environments : on the use of assistive listening devices
Sammanfattning : Assistive listening devices (ALDs) are used in classrooms to assist communication for students with hearing loss. An ALD, a system of external microphones, transmits sound directly to the students' hearing aids. The signal is coupled to the hearing aid using a radio frequency (FM) or an induction loop (IL) system. LÄS MER
4. Room acoustics and cognitive load when listening to speech
Sammanfattning : The present thesis investigated the effects of background noise or a long reverberation time in learning situations. All studies used spoken texts that were presented above the speech intelligibility threshold, but were degraded enough to make listening more effortful. LÄS MER
5. Communication quality : a conceptual approach focusing on classroom assistive listening devices
Sammanfattning : In a classroom an assistive listening device (ALD) is a system of external microphones that transmit sound from a sound source directly to students' hearing aids. An ALD can be a microphone close to the mouth which transmits a voice directly to listeners' hearing aids. LÄS MER
