In the course of two experimental studies the individual evaluations of noise annoyance during sound exposure were compared with the experimental auditory fatigue (TTS) and the recovery functions. In both studies, in fourteen young men with normal hearing capacity, a temporary threshold shift was built up and then the subjects were submitted during the recovery period to different second-noise levels (narrow band noise and white noise). The loudness estimations and the evaluations of noise annoyance were scaled at the same points as TTS was measured. The poststimulatory recovery of hearing was significantly delayed, even at noise levels of 65 and 75 db. The evaluations of loudness and noise annoyance corresponded well with the recovery of hearing. In the first experiment, the mean values of noise annoyance ratings increased after 16 min of the second noise exposure, in spite of a further decrement of auditory fatigue. In the second experiment, the mean values of noise annoyance ratings remained almost unchanged during the secondary noise exposure. Regarding individual evaluations, however, the noise annoyance ratings of half of the subjects increased whereas the other half decreased. These results are interpreted as a habituation respectively a sensitization process.
在两项实验研究过程中，将声音暴露期间对噪声烦恼的个体评估与实验性听觉疲劳（暂时性阈移）及恢复功能进行了比较。在这两项研究中，对14名听力正常的年轻男性建立了暂时性阈移，然后在恢复期让受试者暴露于不同的二次噪声水平（窄带噪声和白噪声）。响度估计和噪声烦恼评估在测量暂时性阈移的相同时间点进行。即使在65和75分贝的噪声水平下，刺激后的听力恢复也显著延迟。响度和噪声烦恼评估与听力恢复情况吻合良好。在第一个实验中，尽管听觉疲劳进一步减轻，但在二次噪声暴露16分钟后，噪声烦恼评级的平均值仍有所增加。在第二个实验中，二次噪声暴露期间噪声烦恼评级的平均值几乎保持不变。然而，就个体评估而言，一半受试者的噪声烦恼评级增加，而另一半则下降。这些结果分别被解释为一种习惯化或敏感化过程。
