Individually-guided Hearing Aid Fitting

Who can take part

• sensorineural hearing loss with pure-tone thresholds 70 dB HL or better at octave frequencies between 250 and 4000 Hz, 4 (.5, 1, 2, 3 kHz)
• frequency pure-tone average (PTA) of ≥ 30 dB HL
• Listeners will have symmetrical losses, defined here as a 4-frequency PTA difference between ears ≤ 20 dB HL

Who cannot take part

• Hearing loss remediated with a cochlear implant (cannot wear hearing aids)
• Significant history of otologic or neurologic disorders
• Any clinically significant unstable or progressive medical condition
• Any condition which, in the opinion of the investigator, places the participant at unacceptable risk if he or she were to participate in the study
• recent (within last 12 months) hearing aid use
• conductive loss (air-bone gaps > 10 dB at any frequency and/or abnormal immittance) -
• scoring < 23 on the Montreal Cognitive Assessment
• Hearing loss exceeding the limits that can be successfully aided with hearing aids (i.e., profound hearing loss)
• Non English speaking participants
