Assessment of Novel Sound Changing Principles in Hearing Instruments to Determine Their Application
Participants will take part in both a passive and active emotion recognition task: (1) passively listening to semantically-neutral sentences with emotional prosody, and (2) actively listening and subsequently categorizing emotional sentences and sounds.
Participants are seated and instructed to stare at a fixation cross while the stimulus is played.
During this study, non-invasive physiological measurements of pupil dilation will be recorded from the participants.
Using this paradigm we will be assessing the effect of frequency lowering on emotion recognition.
The study takes the form of a partly three factorial design (passive task x frequency lowering x acclimatization).
Participants also perform a two factor design (active task x frequency lowering).
Each participant performs two passive tests (20 minutes long each) with frequency lowering on and off, and a four week acclimatization period in-between.
Participants perform one active listening task after the acclimatization period with frequency lowering on and off.

Våben og indgreb
Deltagergruppe / Arm |
Intervention / Behandling |
|---|---|
|
Aktiv komparator: Hearing Aid without frequency lowering enabled
|
Each participant will be fitted with frequency lowering disabled.
Disabled means standard hearing loss compensation without lowering higher frequencies in lower frequency areas.
The input frequency is mapped to the same frequency in output.
|
|
Eksperimentel: Hearing Aid with frequency lowering enabled
|
Each participant will be fitted with frequency lowering enabled.
The principle of the frequency lowering algorithm is to lower high frequencies to a lower frequency region with the aim of ensuring high frequency audibility to improve auditory emotion recognition.

Changes in event-related-pupil-dilations (ERPDs) data
Tidsramme: 6 weeks
|
Pupil dilations will be recorded from the participant both before and during the performance of the auditory tasks.
Analyses will be carried out relative to the baseline recording (made before the auditory tasks) and also the pre-trial baseline (measured one second prior to the onset of the stimulus), in order to account for differences in baseline physiological activity.
It is planned to analyse event-related-pupil-dilations (ERPDs).

self-perceived speech intelligibility rating
Tidsramme: 6 weeks
|
Subjective speech intelligibility will be assessed through self-perceived speech intelligibility on a continuous scale from 0 (nothing) to 100 (everything) during a training phase only.

behavioral emotion recognition categorical rating
Tidsramme: 6 weeks
|
Behavioral ratings will be assessed in the final stage of the study during the active task.
Participants will categorize stimuli into emotion categories (happy, sad, etc.) in a forced-choice task after each auditory stimulus is played.

|
behavioral emotion recognition continuous rating
Tidsramme: 6 weeks
|
Behavioral ratings will be assessed in the final stage of the study during the active task.
Participants rate the valence and arousal of the stimulus on a continuous scale from 1 (very low) to 9 (very high) after each auditory stimulus is played.
