Participants
Criteria for inclusion were individuals seen at the institution, aged ≥
60 years, with sensorineural, symmetric, and moderate hearing loss
(air-conduction thresholds of 250-4000 Hz not exceeding 60 dB
bilaterally) clinical indication of hearing aid use and naive to sound
amplification products. Individuals who died or failed to attend the
follow-up visits were excluded. Data collection was carried out between
2015 and 2016.
We did not change the original methods we designed after this trial was
started.
The flow diagram of enrollment, gain prescription, and algorithms
activated in each group are depicted in Figure 1.
