Tinnitus occurs with or without prior noise exposure (noise-induced tinnitus (NIT) and spontaneous tinnitus (ST)), and is considered a symptom related to permanent hearing impairment (HI) or temporary hearing threshold shift (TTS).
To carry out a cross-sectional interview study on TTS, ST and NIT during a standard audiometric screening of 756 7-year-old children in Gothenburg.
41% out of 756 children reported either NIT or ST on several occasions, 17% reported recurrent TTS and 7% failed the audiometry screening. The probability of ST was 27% for children with no HI or TTS (OR=1.23 (95% CI 1.12 to 1.34)) but 63% (OR=1.16 (95% CI 1.02 to 1.33)) if exhibiting both HI and TTS.
This study confirms an increased occurrence of spontaneous tinnitus in children with TTS or HI and in children with both TTS and HI, in particular, but also in children with normal hearing. Possibly, tinnitus in young children correlates with stress as in adolescents and adults.
耳鸣可发生于噪声暴露前或后（噪声性耳鸣（NIT）和自发性耳鸣（ST）），并被认为与永久性听力损伤（HI）或暂时性听阈移位（TTS）相关的症状。
在哥德堡对 756 名 7 岁儿童进行标准听力筛查期间，开展 TTS、ST 和 NIT 的横断面访谈研究。
756 名儿童中有 41%多次报告 NIT 或 ST，17%报告复发性 TTS，7%未通过听力筛查。无 HI 或 TTS 的儿童发生 ST 的概率为 27%（OR=1.23（95% CI 1.12 至 1.34）），但同时存在 HI 和 TTS 的儿童发生 ST 的概率为 63%（OR=1.16（95% CI 1.02 至 1.33））。
本研究证实，TTS 或 HI 儿童以及同时存在 TTS 和 HI 的儿童，特别是听力正常的儿童，自发性耳鸣的发生率增加。可能，幼儿的耳鸣与青少年和成年人的压力有关。
