目的在本研究中，我们将我们实验室为非处方助听器开发的循证预设的增益频率响应的功效和有效性与传统国家声学实验室的非线性拟合程序版本2（NAL-NL 2）进行了比较增益频率响应和个人声音放大产品（PSAP）的频率响应。我们假设，与我们的助听器将执行更好的PSAP与差的频率响应和听力与NAL-NL 2频率response.MethodWe使用单盲，随机交叉设计，比较可听度，语音识别，音质，听的努力，在实验室环境和随后的现场试验中，对37名参与者的主观偏好进行了研究。在大多数测量域中具有NAL-NL 2增益频率响应。在实验室测试和现实世界测量中的语音识别中，在听力努力和音质方面，使用PSAP的性能优于PSAP增益-频率响应。我们还发现，大多数参与者（54.05%）更喜欢我们的PSAP，并愿意支付更多的钱购买助听器与我们的PSAP。ConclusionOur循证的PSAP有更好的结果比PSAP与一个单一的，不适合的频率响应，同时执行PSAP的临床最佳实践国家声学实验室的条件。
PurposeIn this study, we compare the efficacy and effectiveness of gain–frequency responses of evidence-based presets developed by our lab for over-the-counter hearing aids to conventional National Acoustic Laboratories' nonlinear fitting procedure, version 2 (NAL-NL2) gain–frequency response and to gain–frequency response of a personal sound amplification product (PSAP). We hypothesized that the hearing aids with our presets would perform better than a PSAP with poor frequency response and comparably to the hearing aid with NAL-NL2 frequency response.MethodWe used a single-blinded, randomized cross-over design to compare audibility, speech recognition, sound quality, listening effort, and subjective preferences in 37 participants in laboratory settings and following field trials.ResultsThe presets developed in our lab showed comparable outcomes to the hearing aids with NAL-NL2 gain–frequency response in most measured domains. Performance with the presets was better than the PSAP gain–frequency response in the domains of listening effort and sound quality in laboratory testing and speech recognition in our real-world measures. We also found that most participants (54.05%) preferred our presets over the PSAPs and were willing to pay significantly more to purchase the hearing aids with our presets.ConclusionOur evidence-based presets have better outcomes than a PSAP with a single, poorly suited frequency response while performing comparably to the clinical best-practice National Acoustic Laboratories condition.
