Consideration of Sufficient and Insufficient Benefits in Hearing Aid Fitting.

ABSTRACT:

Background

During hearing aid (HA) fitting, individuals may experience better speech discrimination at normal speech levels and worse discrimination at loud speech levels than without an HA. Therefore, we investigated factors that worsen speech discrimination when the speech sound level increases.

Methods

Speech discrimination was measured in patients aged >20 years who had average hearing thresholds <90 dB on pure-tone audiometry. An insufficient benefit was defined as speech discrimination being better at 65 dB sound pressure level (SPL) with HAs than without HAs and worse at 80 dB SPL.

Results

Of the 251 participants (296 ears), 229 and 25 had sufficient benefit and insufficient benefit, respectively. Functional gains (FGs) of sufficient benefit were approximately
