Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The goal of this clinical trial is to optimize hearing aid benefit based on the individual auditory-cognitive need using different hearing aid features in first-time hearing aid users between 45-80 years old with bilateral Phonak Audéo Paradise/Lumity 70/90 hearing aids. The main questions it aims to answer are:

Does cognitive functioning affect hearing aid benefit? How can hearing aid fitting be optimized based on the individual auditory-cognitive profile?

The hypothesis posits that cognitive abilities influence the effectiveness of hearing aids, alongside hearing status. Furthermore, if features of hearing aids improve speech understanding and listening effort, it is proposed that individuals with lower cognitive functioning will experience heightened benefits from hearing aids.

The study will consist of three groups: one control group and two groups where one different feature will be modified.

Participants will be tested at baseline measurement, including:

* screening tests
* audiological tests
* questionnaires
* cognitive tests
* real-ear-measurement

Following this, participants will be divided in one of the three groups, after which speech audiometry will be repeated. After a 4-week acclimatization period, the second measurement will take place, repeating speech audiometry and questionnaires. Subsequently, the hearing aid settings will be restored to their initial configuration.

Participants

Study Groups

Review each arm or cohort in the study, along with the interventions and objectives associated with them.

Individuals between 45-80 years with bilateral hearing aids (control group)

Within this control group, no changes will be made to the hearing aid settings. However, they undergo all other tests of the test protocol.

Group Type OTHER

Cognitive screening and vision screening

Intervention Type BEHAVIORAL

The Dutch Montreal Cognitive Assessment will be assessed. The Snellen Eye Test will be used to screen for normal or corrected-to-normal vision.

Audiological Assessment

Intervention Type BEHAVIORAL

Three audiological tests are included: 1) Tympanometry to assess the middle ear status, 2) Pure-tone audiometry with headphone to evaluate the hearing thresholds, 3) Speech audiometry in free field to assess the ability to understand spoken sentences in quiet and in the presence of background noise.

Questionnaires

Intervention Type BEHAVIORAL

Three questionnaires are included:

1. The HAVICOP questionnaire to assess the hearing-related quality of life (Ceuleers, D., Baudonck, N., Keppler, H., Kestens, K., Dhooge, I., \& Degeest, S. (2023). Development of the hearing-related quality of life questionnaire for auditory-visual, cognitive and psychosocial functioning (hAVICOP). Journal of communication disorders, 101, 106291.)
2. the FAS (fatigue assessment scale) to assess how you usually feel
3. the EEAS (extended effort assessment scale) to assess how you experience listening in everyday life.

Cognition

Intervention Type BEHAVIORAL

Four cognitive functions, important for speech understanding, will be assessed both audibly and visually: divided attention, working memory, processing speed, and cognitive flexibility and inhibition.

Real ear measurement

Intervention Type OTHER

This test will give an objective assessment of the hearing aids' configuration.

Individuals between 45-80 years with bilateral hearing aids (frequency compression)

Within this experimental group, a slight modification (which differs between groups) will be made to the basic hearing aid setting.

Group Type EXPERIMENTAL

Hearing aid feature adjustment (frequency compression) of the following hearing aids: Phonak Audéo Paradise/Lumity 70

Intervention Type DEVICE

Upon enrollment, each participant will be allocated to one of three research groups and participants will remain unaware of their group assignment. This groups will undergo a slight modification, namely frequency compression turned off, to the basic setting.

Cognitive screening and vision screening

Intervention Type BEHAVIORAL

The Dutch Montreal Cognitive Assessment will be assessed. The Snellen Eye Test will be used to screen for normal or corrected-to-normal vision.

Audiological Assessment

Intervention Type BEHAVIORAL

Three audiological tests are included: 1) Tympanometry to assess the middle ear status, 2) Pure-tone audiometry with headphone to evaluate the hearing thresholds, 3) Speech audiometry in free field to assess the ability to understand spoken sentences in quiet and in the presence of background noise.

Individuals between 45-80 years with bilateral hearing aids (noise reduction)

Within this experimental group, a slight modification (which differs between groups) will be made to the basic hearing aid setting.

Group Type EXPERIMENTAL

Hearing aid feature adjustment (noise reduction) of the following hearing aids: Phonak Audéo Paradise/Lumity 70

Intervention Type DEVICE
