In the present study we examined the relationship of the loudness discomfort level LDL of different signals. We carried out measurements in 97 patients, all of whom suffered from a sensorineural hearing loss. The results showed almost no difference between the LDL of pure tones and narrow band noise. The LDL of broad band noise showed a good correlation to the LDL of 250 Hz. Only the LDL of monosyllables ranged at a higher SPL. For an up-to-date hearing aid fitting, all forms of LDL should be taken into consideration. This is especially necessary when using digital hearing aids.
在本研究中，我们考察了不同信号的响度不适阈（LDL）之间的关系。我们对97例患有感音神经性听力损失的患者进行了测量。结果显示，纯音和窄带噪声的LDL之间几乎没有差异。宽带噪声的LDL与250Hz的LDL显示出良好的相关性。只有单音节词的LDL处于较高的声压级。为了进行最新的助听器验配，应考虑所有形式的LDL。在使用数字助听器时，这一点尤为必要。
