Real-life efficacy and reliability of training a hearing aid
MetadataShow full item record
We investigated if training of hearing aids result in effective and reliable outcomes. Hearing-2 impaired adults trained the compression characteristic from the NAL-NL2 prescription for 3 three weeks and compared their trained response with the prescription for two weeks. The 4 training and comparison trials were repeated. We found that for 80% of those who trained 5 the devices away from the prescription, training was effective. Significant correlations were 6 seen between trained variations for 63% of participants, with consistent trained variations 7 leading to consistent preferences across trials, and vice versa. Based on our data we present 8 a guideline for clinically managing training with clients.
