Normal-hearing men and women (N: 20) judged damped wave signal trains (3/sec; fc = .35, .5, .7, 1, 1.4, 2, 2.8, or 4 kc/s) to be on the verge from "normal" to "loud," and from "normal" to "soft." Judgments were binaural about 1 m from a loudspeaker. "Normal" (most comfortable ?) loudness was calculated at halfway in db between the two transition zones. A replication showed that 70% of Ss yielded the same "Normal" within 9 db for all fc, while only 35% could yield the same "Normal" within 6 db for all fc. Mean "Normal" for 1 kc/s was 72.8 db SPL re 20 mu Pa. Ss made equal-loudness judgments by adjusting other fc to this standard. Variances of equal-loudness judgments were 2--3 times better (smaller) than of "Normal" estimates. It was suggested that "Otometry" utilize the equal-loudness measurement procedure recommended originally by Victoreen (J. Acoust. Soc. Am., 1974, 55, 309-312).
听力正常的男性和女性（N = 20）判断阻尼波信号序列（3次/秒；fc = 0.35、0.5、0.7、1、1.4、2、2.8或4千周/秒）处于从“正常”到“响亮”以及从“正常”到“轻柔”的临界状态。判断是在距离扬声器约1米处双耳进行的。“正常”（最舒适？）响度是在两个过渡区域之间的分贝值的中间点计算得出的。一次重复实验表明，70%的受试者在所有fc条件下能在9分贝范围内得出相同的“正常”响度，而只有35%的受试者在所有fc条件下能在6分贝范围内得出相同的“正常”响度。1千周/秒时的平均“正常”响度为72.8分贝声压级（参考20微帕）。受试者通过将其他fc调整到这个标准来进行等响度判断。等响度判断的方差比“正常”估计的方差好（小）2至3倍。有人建议“耳测法”采用维克托林最初推荐的等响度测量程序（《美国声学学会杂志》，1974年，55卷，309 - 312页）。
