Beschreibung
Inclusion Criteria:
- Are adults (≥18 years) presenting with "normal hearing" (pure-tone thresholds ≤25 dB HL from 250-4000 Hz) but hearing trouble (≥20 points on RHHI questionnaire)
- Are willing to try amplification (i.e., hearing aids) for the first time
- Can Read/write in American English
- Have access to email, internet, and phone
Exclusion Criteria:
- Participants with self-reported otologic history (e.g., ear surgery, ototoxic medications, middle-ear dysfunction, holes in ear drums)
- Have moderate to severe traumatic brain injury
- Have bothersome tinnitus as their primary complaint
- Have a health condition that would interfere with study participation (e.g., dementia/cognitive disorder, blindness)
- Prior hearing aid use

Intervention / Behandlung |
|---|---|
|
Experimental: Open-dome receiver-in-canal hearing aids
Air-conduction receiver-in-canal (RIC) hearing aids with open domes, which have holes or vents that let natural sound and air pass into the ear canal.
|
Participants will be randomly assigned to either the open dome or closed dome group (Factor 1). Participants will then obtain their first treatment arm with a random assignment of either an SNR neutral (SNR-) or SNR enhanced (SNR+) hearing aid fitting (Factor 2). They will return to the lab for testing prior to crossing over to the second arm (the other SNR configuration: SNR- or SNR+). The SNR+ setting contains features to improve the signal-to-noise ratio of the sound to optimize speech over noise through the hearing aids. Participants will be randomly assigned to either the open dome or closed dome group (Factor 1). Participants will then obtain their first treatment arm with a random assignment of either an SNR neutral (SNR-) or SNR enhanced (SNR+) hearing aid fitting (Factor 2). They will return to the lab for unaided baseline testing prior to crossing over to the second arm (the other SNR configuration: SNR- or SNR+). The SNR- setting contains focuses on improving audibility of sounds through the hearing aids. |
|
Experimental: Closed-dome receiver-in-canal hearing aids
Air-conduction receiver-in-canal (RIC) hearing aids with closed domes, which have solid rubber with tiny or no vents to seal the ear.
|
Participants will be randomly assigned to either the open dome or closed dome group (Factor 1).

Ergebnis Maßnahme |
Maßnahmenbeschreibung |
Zeitfenster |
|---|---|---|
|
Revised Hearing Handicap Inventory (RHHI)
Zeitfenster: Baseline (unaided), 4 weeks (aided with intervention 1), 4 weeks (after wash-out period, and unaided), and 4 weeks (aided with intervention 2)
|
18-item questionnaire that assesses self-perceived hearing difficulty associated with social and emotional situations and is considered a hearing-related quality of life measure.
Higher scores indicate MORE hearing difficulty.
Administered unaided and aided.
Scores range from 0 - 72.
|
Baseline (unaided), 4 weeks (aided with intervention 1), 4 weeks (after wash-out period, and unaided), and 4 weeks (aided with intervention 2)

Abbreviated Profile of Hearing Aid Benefit (APHAB)
Zeitfenster: Baseline (unaided), 4 weeks (aided with intervention 1), 4 weeks (after wash-out period, and unaided), and 4 weeks (aided with intervention 2)
|
24-item questionnaire used to assess hearing problems in various listening environments (e.g., quiet, background noise, reverberation, and aversiveness to sound).
Higher scores indicate greater hearing problems.
Administered unaided and aided.
Scores range from 1% to 99%.
|
Baseline (unaided), 4 weeks (aided with intervention 1), 4 weeks (after wash-out period, and unaided), and 4 weeks (aided with intervention 2)

|
Words in Noise (WIN) Test
Zeitfenster: Baseline (unaided), 4 weeks (aided with intervention 1), 4 weeks (after wash-out period, and unaided), and 4 weeks (aided with intervention 2)
|
35-word recognition in noise test with 5 words at each of the 7 signal-to-noise ratios that go from 24 dB SNR to 0 dB SNR in 4-dB decrements.
The noise (six talker babble) is held constant with the level of the words varying to make up the SNRs.
Listener repeats words in background noise of talkers where the words get progressively softer.
Higher scores indicate more trouble hearing in noise.
Administered unaided and aided.
Scores range from 0dB to 24dB.
