Eligibility
Inclusion criteria
Inclusion criteria: Hearing impaired group:Hearing thresholds: ear of interest/best ear: Mild flat pure-tone air-conduction hearing loss in the lower frequencies gradually sloping to moderate to serious pure-tone air-conduction hearing loss in the higher frequencies. Other ear: essentially equal or worse hearing loss. Normal hearing group: (Sub)normal pure-tone air-conduction thresholds at all relevant octave frequencies;No air-bone gap Age: adults Native language: Dutch Negative otologic history (except for the hearing impaired group)
Exclusion criteria
Exclusion criteria: Neurological problems, asked for during anamnesis if the subject has visited a neurologist in the past 10 years Speech/Language disorder Native language other than Dutch Positive otologic history (only for normal hearing group) Contralateral ear is not properly maskable.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Per group the speech reception threshold (SRT) at different degrees of distortion of the time and frequency signal cue. | — |
Secondary
| Measure | Time frame |
|---|---|
| 1. Normative data for normal hearing on these tests. 2. For individuals the performance on the different modifications of the Digit-In-Noise (DIN) tests w.r.t. the performance on the DIN test itself. | — |
