Three preventive measures for noise-induced hearing loss

自十八世纪工业革命以来,各项产业的快速发展使得人类物质生活变的富裕,然而伴随而来的却是对环境各种不等程度的破坏,其中一项因应人类文明而产生的文明病即为噪音性听力损失(Noise induced hearing loss–NIHL),此亦为职业性听力损失的主要原因。由于其导因是环境中的噪音,所以其形成并非不可抗拒,为了能对其有所预防,对噪音性听力损失有所认识便成今日重要的课题。

  噪音性听力损失的进程是很缓慢的,据Jinghao听力助听器了解,通常为两耳对称性的缺损而且几乎不会造成极重度听力损失,一旦不再暴露在噪音下,就不会有噪音暴露所造成的更进一步听力损失。最大的听力损失通常发生在4000Hz左右,在稳定的噪音暴露状态下,3K、4K及6KHz的听力损失通常在10到15年左右达到最大值。此外,持续性噪音暴露比间歇性噪音暴露更有伤害性,因为后者让耳朵有休息时间。

  在噪音性听力损失的预防及处置方面,Jinghao听力助听器官网认为通常可以分为以下三方面。

The first level of prevention refers to the prevention of harmful noise to the human body. For example: use less noisy equipment, change working methods, set up soundproofing equipment, use ear muffs or earplugs, canal caps, etc.

The second level of prevention, that is, regular hearing tests, can detect the effects of harmful mechanisms (ie, hearing loss) early.

The third level of prevention, improve and reduce the damage of the aids, such as the selection of appropriate hearing aids, so as not to cause more damage.

In addition to reducing the noise impact through the use of protective tools, the professional workplace should also be recommended and used to assess the noise level of the workplace, including hearing tests, questionnaires, follow-up examinations, hearing protection promotion and education, and hearing protection.

  Jinghao听力助听器官网认为,由于社会文明、工业进步,工作中的噪音引起的失听已经形成一个严重的社会问题,对人类健康也是一个大问题。长期的噪音也会使得人们的工作效率降低、记忆力变差、经常焦虑不安并使心脏血管疾病产生率增高。因此,噪音的防制与定期的听力检查在职业安全上是个重要的课题。
