Normal-hearing young adults (N: 30) produced 3 fixed-frequency monaural audiograms by Bekesy tracking on a Grason-Stadler E-800 audiometer (modified for high frequencies) for pulsed pure tones in 2-kc/s steps progressively from 7-19 kc/s. The earphone was not moved between one pair of audiograms but was removed and replaced between another pair. After 1 mo, 16 Ss returned for retest on the HF E-800 audiometer and on a similar audiometer using the conventional Method of Limits. Maximum group mean retest HTL differences approximated 5 db. Statistical analysis indicated that the arrays of HTLs within and across sessions were equivalent. Reliability and validity coefficients were high and significantly different from zero. It was concluded that the HF E-800 could with such Ss be used with some confidence to assess high-frequency sensitivity.
听力正常的年轻成年人（N = 30）在一台经高频改装的Grason-Stadler E - 800听力计上，通过Bekesy跟踪法生成了3个固定频率的单耳听力图，测试的脉冲纯音频率以2千赫兹的步长从7千赫兹逐步递增到19千赫兹。在绘制一对听力图的过程中耳机位置不动，但在绘制另一对听力图时需取下并重新放置耳机。1个月后，16名受试者返回，使用高频E - 800听力计以及采用传统极限法的类似听力计进行复测。最大组平均复测听力阈值（HTL）差异约为5分贝。统计分析表明，各时段内和各时段间的听力阈值阵列是等效的。信度和效度系数很高且显著不为零。得出的结论是，对于此类受试者，高频E - 800听力计可在一定程度上用于可靠地评估高频听力敏感度。
