Brief summary

Evaluating the efficacy and effectiveness of an advancement in the fitting characteristics of extended wear technology with the commercially available device as a comparator.

Detailed description

A interventional study in which participants will be fit with the commercially available device in one ear and the experimental device in the opposite ear. After two weeks, the devices will be switched so that the participant has worn each device in each ear for a total of 2 weeks. Participants will be blinded as to which device they are wearing in each ear. Comfort and sound quality will be assessed for each device prior to removing from ears.

Interventions

DEVICELyric extended wear hearing aid device A

Current commercially available extended wear hearing aid

DEVICELyric extended wear hearing aid with fitting modification device B

Extended wear hearing aid with fitting modifications

Masking description

Participants will not know which device is in each ear, only that they are being fit with Lyric devices.

Intervention model description

Participants will be fit with commercially available extended wear hearing aid device A in the right ear and extended wear hearing aid with fitting modifications device B in the left ear for two weeks (first intervention); then fit with extended wear hearing aid with fitting modifications device B in the right ear and commercially available extended wear hearing aid device A in left ear for two weeks (second intervention). There will be no washout period.

Inclusion criteria

* Mild, Moderate and Moderate Severe Hearing loss * Previous extended wear technology users who rejected or cancelled trials due to discomfort, feedback, migration, or poor sound quality due to fit issues

Exclusion criteria

* Participants who can only wear a size XXS (extra-extra small) extended wear device * asymmetrical hearing loss * other diagnosis that may cause hearing fluctuation * inability to tolerate physical fit of Lyric devices * inability to be seen for four lab visits

MeasureTime frameDescription
Subjective Questionnaire of ComfortTwo weeks after fitting device A in right ear/device B in left ear (Day 14 of study), and two weeks after fitting device A in left ear/device B in right ear (Day 28 of study-final appointment)Subjective ratings of comfort of each device in the ear, on a scale from 0 (very comfortable) to 10 (very uncomfortable/painful). No statistical analysis was planned for this measure.
Subjective Ratings of Occlusion With Both DevicesTwo weeks after fitting device A in right ear/device B in left ear (Day 14 of study), and two weeks after fitting device A in left ear/device B in right ear (Day 28 of study-final appointment)Subjective ratings on how plugged participants' ears felt with each device in ear,on scale from 0 (not at all) to 10 (extremely plugged/cannot tolerate)

Subjective Questionnaire of Comfort

Subjective ratings of comfort of each device in the ear, on a scale from 0 (very comfortable) to 10 (very uncomfortable/painful). No statistical analysis was planned for this measure.

Time frame: Two weeks after fitting device A in right ear/device B in left ear (Day 14 of study), and two weeks after fitting device A in left ear/device B in right ear (Day 28 of study-final appointment)

Population: All participants who were fit with commercially available Lyric extended wear hearing aid device A in right ear and Lyric extended wear hearing aid device B in left ear Day 1- Day 14, and who were fit with extended wear hearing aid device B in right ear and commercially available hearing aid device A in left ear Day 15 to Day 28 of study.
