D-S测试中进行了四项测量。它们是：(1)语音接收阈值，(2)噪声感知阈值，(3)噪声干扰水平，(4)重复语音接收阈值。这些测量之间的关系被用作分离心理耳聋病例的基础。以下一种或多种情况引起怀疑患者表现出非器质性丧失：1)当语音接收受到低于语音呈现水平的噪声干扰水平的抑制时；2)噪声感知阈值小于语音接收阈值；3)当两个语音接收阈值之间存在明显差异时。所提出的各种技术已被成功地应用。通过结合相关的听力图和病史来解释D-S测试，可以获得更多的定义。自从D-S测试被纳入临床常规后，德顺总医院对心理损失的治疗变得更加精确和快速。基本上，D-S测试确定了听力的四个衡量标准。它们是：言语接受阈值；干扰水平;noise-perception阈值;以及语音接收的重复阈值。在高于语音接收阈值5分贝的情况下，连续说出一系列应答。同时引入掩蔽噪声，然后逐渐增大。这个过程一直持续，直到掩蔽噪声达到抑制语音接收和防止患者重复单词的水平。
Four measurements are made in the D-S Test. They are: (1) the speech reception threshold, (2) the noise perception threshold, (3) the noise interference level, and (4) the repeat speech reception threshold. The relationships between these measurements are used as the basis for isolating cases of psychological deafness. One or more of the following conditions raise the suspicion that the patient exhibits non-organic loss: 1) When speech reception is inhibited by a noise interference level less intense than the speech presentation level; 2) when the noise perception threshold is poorer than the speech reception threshold; and 3) when there is sharp discrepancy between the 2 speech-reception thresholds. Variations of the techniques presented have been used successfully. Even more definition can be achieved by interpreting the D-S Test in conjunction with an associated audiogram and a medical history. Treatment of psychogenic losses encountered at Deshon General Hospital has become more precise and rapid since the D-S Test was incorporated as a clinical routine. Basically, the D-S Test determines four measurements of audition. These are: Speech-reception threshold; noise-interference level; noise-perception threshold; and a repeat threshold on speech reception. A continuous series of spondees is spoken 5 db above the speech reception threshold. Simultaneously, the masking noise is introduced and then gradually increased. This procedure is continued until the masking noise reaches a level where it inhibits speech reception and prevents repetition of the words by the patient.
