AC HTLs were measured on 12 normal-hearing young adults by (a) standardized manual, (b) self-recording (Bekesy), and (c) microprocessor audiometry stimulating standard manual procedure, to determine how threshold measurements would be affected by the 3 methods of testing when utilized in industrial hearing conservation programs for compliance with federal agency recommendations. Self-recording audiometry resulted in mean thresholds lower than standard manual audiometry by from 1-9 db; microprocessor audiometry resulted in thresholds higher than standard manual audiometry by from 0.2-4.4 db except at 4 kc/s where the microprocessor mean threshold was 3.8 db lower. Thus microprocessor audiometry more closely approximated audiometry by standard manual procedure. All 3 methods required 7-8 min per S for a 7-frequency audiogram on both ears.
对12名听力正常的年轻人进行了听觉脑干反应阈值（AC HTLs）测量，测量方式如下：（a）标准化手动测量；（b）自记录（贝凯西）测量；（c）微处理器听力测定法模拟标准化手动测量程序，目的是确定在工业听力保护项目中采用这三种测试方法以符合联邦机构建议时，阈值测量会受到怎样的影响。自记录听力测定法得出的平均阈值比标准化手动听力测定法低1至9分贝；微处理器听力测定法得出的阈值比标准化手动听力测定法高0.2至4.4分贝，但在4千赫兹时，微处理器的平均阈值低3.8分贝。因此，微处理器听力测定法更接近标准化手动测量程序的听力测定结果。三种方法对双耳进行7频率听力图测量时，每位受试者每次均需要7至8分钟。
