A procedure of hearing aid evaluation by brainstem-evoked response audiometry (BERA) is described. The vailidty of the method is tested with regard to amplitude scattering (51 subjects) and by comparison of hearing aid parameters determined by speech audiometry (205 subjects) respectively by BERA (50 subjects). The results indicate that the influence of intra-individual amplitude variation on the reliability of the procedure is of minor importance only. Comparisons of gain and compression requirement determined by speech audiometry, respectively by BERA, show good agreement, proving the clinical importance and validity of hearing aid selection by BERA. Compression factors of available hearing aids, however, are poorly correlated with estimated compression requirements: only 22% of the hearing aids meet the requirements of about 80% of the subjects.
描述了一种通过脑干诱发反应测听法（BERA）进行助听器评估的程序。分别针对幅度散射（51名受试者）以及通过言语测听法（205名受试者）和BERA（50名受试者）确定的助听器参数比较来测试该方法的有效性。结果表明，个体内幅度变化对该程序可靠性的影响仅具有较小的重要性。通过言语测听法和BERA分别确定的增益和压缩要求的比较显示出良好的一致性，证明了通过BERA选择助听器的临床重要性和有效性。然而，现有助听器的压缩因子与估计的压缩要求相关性较差：只有22%的助听器符合约80%受试者的要求。
