The Effect of Different Adaptation Formulas on Mid-Latency Auditory Evoked Potentials in Adults with Hearing Aids.

Introduction: We were conducting this study to evaluate the effects of different hearing aid adaptation formulas on middle latency responses (MLR) in adult hearing aid users.

Methods: The study included 72 participants: those with moderate hearing loss using hearing aids with two different formulas for the last year, those with moderate hearing loss not using hearing aids, and those without hearing loss. Sixteen participants using NAL-NL1 and NAL-RP formulas were group 1; twenty using NAL-NL2 and DSL formulas were group 2; fifteen with hearing loss not using devices were group 3; and twenty-one without hearing loss were group 4.
