Trial Outcomes & Findings for Subject´s Preference Regarding Hearing Performance and Functionality Using a New Sound Processor (NCT NCT03848910)

NCT ID: NCT03848910

Last Updated: 2021-10-14

Results Overview

Measuring of subscales Ease of communication, Reverberation, Background noise, Aversiveness and a Global score with the precursor sound processor at Day 0 and with the Investigational device after 6 weeks with a questionnaire. All subscales range from 0-100%, total score is the average of all subscales 0-100%, where 0% indicates no problems and 100% indicates always problem. A decrease in the APHAB values indicates an improvement. The change from visit 1 with the precursor sound processor to visit 3 with the Investigational device is presented. A positive value indicates an improvement with the Investigational device, a negative value an impairment.

Investigational Device - Sound Processor
Investigational device - Sound Processor: At visit 1 the subjects will complete self-reported assessments with respect to "pre-study experience" using precursor Sound Processor (comparator). At visit 1 the subjects will then receive the Investigational device (Sound Processor) which should be used during the following 6 weeks. At visit 3 the subjects will complete self-reported assessments regarding Investigational device and participate in audiology tests regarding both Sound Processors, comparator and Investigational device. The subject shall decide their preferred choice made by selection between Investigational device and the comparator.

PRIMARY outcome

Timeframe: Day 0 and after 6 weeks

Measuring speech, spatial and hearing experiences with the precursor sound processor at Day 0 (Visit 1) and with Investigational device after 6 weeks (Visit 3) with a questionnaire. The Total score summarizes the parameters speech, spatial and hearing. A scale from 0 to 10, where 0 represents "can not hear at all", and 10 "hear perfectly" is used. An increase of a SSQ value reflects an improvement. The change from visit 1 with the precursor sound processor to visit 3 with the Investigational device is presented. A positive value indicates an improvement and a negative value an impairment.

PRIMARY outcome

Timeframe: Baseline at visit 1, 6 weeks after study start at visit 3

To measure threshold audiometry PTA4 (mean of 500, 1000, 2000 and 4000 Hz) with both the precursor sound processor and the Investigational device. The units reported for PTA4 are decibels (dB). The change from visit 1 with the precursor sound processor to visit 3 with the Investigational device is presented. As such, a lower or more negative score is more desirable and reflects a better ability to hear softer sounds.

PRIMARY outcome

Timeframe: Baseline at visit 1, 6 weeks after study start at visit 3

To measure Adaptive speech recognition in noise with the precursor sound processor and the Investigational device. Measured as signal to noise ratio The adaptive speech test in noise was conducted using validated lists of phonetically balanced sentences, with speech and noise presented from the front (0 degrees azimuth). The speech is kept constant at 65 dB Sound Pressure Level (SPL) and the noise is adapted in dB steps to establish the speech-to-noise ratio (SNR) providing a 50% level of understanding. A ratio of 1 reflects the ability to correctly hear sentences at 65 dB, in the presence of 65 dB background noise. A lower ratio than 1 reflects the ability to correctly hear sentences below 65 dB. A ratio higher than 1 reflects the ability to correctly hear sentences presented above 65 dB. A lower or more negative score is more desirable and represent a better hearing in a noisy environment.

To measure Speech in quiet at 50, 65 and 80 dB with the precursor sound processor and the Investigational device. Speech in Quiet presents a list of words in a quiet environment at three different presentations levels, 50, 65 and 80 dB (decibel). The number of correct words perceived at each presentation level are counted and the percentage in relation to the total presented amount of words is calculated. A higher score reflects a higher percentage of correct words perceived, i.e. better hearing in a quiet environment.

Measure Comfort by a visual analogue scale (VAS) 100 mm at Day 0 regarding the precursor sound processor and after 6 weeks regarding the Investigational device. Subject will be asked to put a line where they find most appropriate where 0 mm represents Not comfortable at all and 100 represents Most comfortable imaginable. The distance will be measured with a ruler and presented as a value between 0 and 100. A higher score reflects higher comfort.

Investigational Device - Sound Processor
n=11 Participants
Investigational device - Sound Processor: At visit 1 the subjects will complete self-reported assessments with respect to "pre-study experience" using precursor Sound Processor (comparator). At visit 1 the subjects will then receive the Investigational device (Sound Processor) which should be used during the following 6 weeks. At visit 3 the subjects will complete self-reported assessments regarding Investigational device and participate in audiology tests regarding both Sound Processors, comparator and Investigational device. The subject shall decide their preferred choice made by selection between Investigational device and the comparator.
