中文摘要

背景： 钢琴技师（PTs）是专业用耳人群，其工作依赖高度精细的听觉感知来进行钢琴调律、音色整理和调整，同时暴露于调律本身以及相关木工和金属加工任务可能产生的有害声音。该群体的职业声音暴露和耳健康知识尚未得到系统描述。
方法： 在一项横断面观察性研究中，我们使用校准的个人噪声剂量计在钢琴调律期间量化A计权等效连续（Leq）和8小时归一化（LEX,8h）声级，并辅以参考车间测量。此外，PTs完成了专业用耳者问卷（PEU-Q），以评估耳健康知识和态度。
结果： 共记录12名PTs的102次调律过程（平均时长：74分钟，标准差（SD）：22）。平均调律Leq为76.4 dB(A)（SD：3.2），17.7%的调律过程≥80 dB(A)，1.0%≥85 dB(A)。立式钢琴调律比三角钢琴调律高2.4 dB（P = 0.02）；房间大小无显著影响。车间任务Leq值最高达93 dB(A)，但按活动分组累计LEX,2000h仍≤81 dB(A)。在51名PEU-Q受访者中，耳健康知识存在明显缺口；尽管71%报告担心未来听力损失且听力防护使用广泛，35%从未接受过正式听力检查。
结论： PTs的声音暴露平均为中等水平，但存在不可忽视的高值尾部，尤其是立式钢琴调律和车间任务。结合耳健康意识和获得正式听力保健方面存在的显著缺口，这些发现支持为该专业用耳者群体开展有针对性的教育、个体化噪声风险评估和专门的耳健康路径。

英文摘要

BACKGROUND: Piano technicians (PTs) are professional ear users whose work depends on highly refined auditory perception for tuning, voicing, and regulating the piano while exposing them to potentially hazardous sound from tuning itself and from associated wood- and metalworking tasks. Occupational sound exposure and ear-health knowledge in this group have not been systematically characterized.
METHODS: In a cross-sectional observational study, we quantified A-weighted equivalent continuous (L eq ) and 8-h normalized (L EX, 8 h ) sound levels using calibrated personal noise dosimetry during piano tuning, complemented by reference workshop measurements. In addition, PTs completed the Professional Ear User Questionnaire (PEU-Q) to assess ear health knowledge and attitudes.
RESULTS: A total of 102 tuning sessions were recorded in 12 PTs (mean duration: 74 min, standard deviation (SD): 22). Mean tuning L eq was 76.4 dB(A) (SD: 3.2), with 17.7% of sessions ≥80 dB(A) and 1.0% ≥85 dB(A). Upright tuning was 2.4 dB louder than grand tuning ( P = 0.02); room size had no significant effect. Workshop tasks reached L eq values up to 93 dB(A), yet cumulative L EX, 2000 h per activity grouping remained ≤81 dB(A). Among 51 PEU-Q respondents, ear-health knowledge showed marked gaps; despite 71% reporting concern about future hearing loss and widespread use of hearing protection, 35% had never undergone a formal hearing examination.
CONCLUSION: Sound exposure in PTs is moderate on average but carries a non-negligible upper tail, particularly for upright piano tuning and workshop tasks. Combined with notable gaps in ear-health awareness and access to formal hearing care, these findings support targeted education, individualized noise-risk assessment, and dedicated ear-health pathways for this professional ear user group.
