The presence of subjective tinnitus is an important aspect in the evaluation of hearing loss induced by noise. Tinnitus due to this condition is characterised by a frequency of 3,000 Hz or above and is closely related to the frequency range of maximal hearing loss. Tinnitus below 1,000 Hz is not induced by noise, and indicates the presence of a different cause for the hearing loss. This type of tinnitus should not be regarded as an occupational disease: it requires extensive investigation.
主观性耳鸣的存在是评估噪声所致听力损失的一个重要方面。由这种情况引起的耳鸣的特征是频率在3000赫兹及以上，并且与最大听力损失的频率范围密切相关。1000赫兹以下的耳鸣不是由噪声引起的，表明存在导致听力损失的不同原因。这种类型的耳鸣不应被视为职业病：它需要进行广泛的调查。
