Insertion gain and saturation sound pressure level (SSPL) characteristics of 71 behind-the-ear hearing aids were evaluated in a computer-assisted analysis as acceptable matches to prescriptive insertion gain and SSPL values derived by a variation of the Prescription of Gain and Output, or POGO, technique (McCandless & Lyregaard, 1983). Stringency criteria in a primary analysis varied from +/- 6 to +/- 16 dB and +/- 2 to +/- 8 dB for gain and SSPL, respectively. Three audiometric contours and associated loudness discomfort levels were used in the simulation. Findings indicated that the relationship between tolerances and the number of aids selected as optimally appropriate varied substantially as a function of audiometric configuration. Minimum gain and SSPL tolerance values of +/- 12 dB and +/- 4 dB, respectively, were required to provide a reasonable choice of instruments for a variety of such configurations. Further analyses shed light on the feasibility of using alternative stringency criteria and on the clinical utility of hearing aid selection using small clinic samples.
在计算机辅助分析中，评估了71款耳背式助听器的插入增益和饱和声压级（SSPL）特性，以确定其是否能与通过增益和输出处方（POGO）技术（McCandless和Lyregaard，1983年）的一种变体得出的规定插入增益和SSPL值进行合理匹配。在初步分析中，增益和SSPL的严格标准分别从±6 dB到±16 dB和±2 dB到±8 dB不等。模拟中使用了三种听力测定轮廓和相关的响度不适水平。研究结果表明，公差与被选为最佳合适的助听器数量之间的关系因听力测定配置而异。分别需要±12 dB和±4 dB的最小增益和SSPL公差值，以便为各种此类配置提供合理的仪器选择。进一步的分析揭示了使用替代严格标准的可行性以及使用小型诊所样本进行助听器选择的临床效用。
