Brief Summary
This study aims to evaluate the benefit of bilateral hearing aid use compared to a unilateral hearing aid. Patients with mild to moderate bilateral hearing loss who are considering the purchase of a commercially available hearing aid will be considered for participation. Eligible participants will be randomized to one of the following treatment arms: (1) a bilateral hearing aid fitting group, and (2) a unilateral hearing aid fitting group.

Conditions
Outcome Measures
Primary Outcomes (1)
Change in Hearing Aid Benefit as Measured by Abbreviated Profile of Hearing Aid Benefit (APHAB)
The APHAB score ranges from 1 to 99. The change in APHAB score was calculated as the difference between scores at 3 months and baseline, so the range of possible values for the change score is -98 to 98. A lower APHAB score indicates a better benefit; a negative change score indicates greater benefit at 3 months than at baseline.
Baseline, 3 months
Secondary Outcomes (12)
Hearing Aid Benefit, as Measured by the Measured by Glasgow Hearing Aid Benefit Profile (GHABP)
3 months
Change in Hearing Aid Benefit as Measured by Bamford-Kowal-Bench Speech in Noise (BKB SIN) Test
Baseline, 3 months
Change in Hearing Aid Benefit as Measured by the Abbreviated Word Auditory Recognition and Recall Measure (WARRM)
Baseline, 3 months
Hearing Aid Satisfaction as Measured by Satisfaction With Amplification in Daily Life (SADL) Survey
3 months , 6 months
Change in Hearing Related Quality Life as Measured by Hearing Handicap Inventory for Elderly (HHIE) Survey Completion

Eligibility Criteria
You may qualify if:
- + years of age
- Ability to read and understand English
- Mild to moderate sensorineural hearing loss (defined by a pure-tone average at 500, 1000, and 2000 Hz of \<55 dB HL in each ear, and the 3000 Hz and 4000 Hz threshold \<80 in each ear), based on a hearing test obtained within the last 6 months by a licensed audiologist.
- Symmetrical hearing loss defined by \<20 dB difference between the pure-tone average of 500, 1000, and 2000 Hz between ears)
- Interested in purchasing hearing aids, but is open minded about trying one or two hearing aids
- No prior hearing aid use longer than 3 months (as documented via self-report)
- Adequate literacy to complete questionnaires
- Willing to purchase study-specific hearing aid(s)
- Access to a smart phone and the internet
You may not qualify if:
- Concerns for middle ear pathology (e.g., air bone gap of \>15 dB at 2 consecutive octave frequencies in either ear)
- Concerns for retrocochlear pathology by audiologist (e.g unilateral tinnitus or ear fullness, referral to ENT/Auditory Brainstem Response testing to r/o acoustic neuroma)
- Severe tinnitus as the reason for seeking amplification
- Co-morbid condition that would interfere with study (e.g., dementia, blindness, neurologic pathology)
- History of fluctuating hearing loss
