To assess the influence on speech intelligibility of various signals used in tinnitus sound therapy.
We measured, in normal hearing subjects, the intelligibility of speech in the presence of three different sound therapy signals: wide-band noise, a recording of moving water, and a combination of tones.
For a given level of stimulation, speech intelligibility was worst in the presence of wide-band noise, compared with the other sound therapy signals. When the stimulation level of the three different signals was increased, speech intelligibility deteriorated more rapidly with wide-band noise, compared with the other two signals. The combination of tones had the least influence on speech intelligibility.
The use of different tinnitus sound therapy signals can lead to significantly different effects on the intelligibility of speech. The use of natural sound recordings or combinations of tones may provide the patient with more flexibility to change the stimulation level during treatment.
评估耳鸣声治疗中使用的各种信号对言语可懂度的影响。
我们在听力正常的受试者中测量了在三种不同的声治疗信号存在时的言语可懂度，这三种信号分别为：宽带噪声、流水录音以及音调组合。
在给定的刺激水平下，与其他声治疗信号相比，在宽带噪声存在时言语可懂度最差。当三种不同信号的刺激水平增加时，与其他两种信号相比，宽带噪声使言语可懂度下降得更快。音调组合对言语可懂度的影响最小。
使用不同的耳鸣声治疗信号会对言语可懂度产生显著不同的影响。使用自然声音录音或音调组合可为患者在治疗期间改变刺激水平提供更大的灵活性。
