What this Trial Is About
The overarching hypothesis to be evaluated using this protocol is that age-related hearing loss (ARHL) leads to shifts in the functional spatial boundaries between segregated and integrated auditory streams, and that hearing aid intervention that relies on directional processing schemes is most effective for those that have the poorest spatial sensitivity. One key component of the research design is to measure both behavioral and neurophysiological indices of an individual's spatial segregation boundary. The second key component is to measure the cost or benefit associated with hearing aid intervention in older hearing-impaired listeners. The final component is to relate cost and benefit of hearing aid intervention to spatial sensitivity measures that might predict the efficacy of clinical intervention.

Eligibility Criteria
You may qualify if you...
- Participants aged 18 to 35 years (young normal-hearing group) or 60 to 80 years (older normal-hearing and older hearing-impaired groups)
- Normal-hearing participants have hearing thresholds 60 dB HL at octave frequencies from 0.25 to 4 kHz and 630 dB HL up to 8 kHz
- Hearing-impaired participants have bilateral, symmetric sensorineural hearing loss with pure-tone thresholds between 35 to 50 dB HL from 0.25 to 2 kHz and 50 to 70 dB HL from 3 to 8 kHz
- Hearing-impaired participants are candidates for or experienced users of hearing aids
- Fluent in English for speech testing
- Montreal Cognitive Assessment (MoCA) score above 22
- Hearing-impaired participants have stable mild-to-moderately severe sensorineural hearing loss confirmed by air- and bone-conduction audiometry and normal tympanograms
You will not qualify if you...
- History of head trauma, traumatic brain injury, epilepsy, seizures, or other neurological disorders in the past 12 months
- History of otologic surgical procedures in the past 12 months
- Active fluctuating hearing loss
- Acute Meniere's disease or labyrinthitis
- Conductive hearing loss
- Use of ototoxic medications in the past 12 months
