Noise-induced hearing loss is almost always preventable if properly fitted hearing protectors are worn to reduce exposure. Many individuals choose not to wear hearing protection because it may interfere with effective communication in the workplace or it may be uncomfortable. Hearing protector comfort has not received the same amount of attention as noise reduction capability. The present study was conducted to evaluate the comfort level of two different types of insert earplugs as well as the attenuation levels achieved by the earplugs. Attenuation levels were obtained with a commercially available earplug fit-test system, and the comfort ratings were obtained by questionnaire. The primary research objective was to determine whether hearing protector comfort was related to measured attenuation values. A linear mixed effects model provided evidence for an inverse relationship between comfort and attenuation.
如果佩戴合适的听力保护器以减少暴露，噪声性听力损失几乎总是可以预防的。许多人选择不佩戴听力保护器，因为它可能会干扰工作场所的有效沟通，或者可能会让人不舒服。听力保护器的舒适度没有得到与降噪能力同等程度的关注。本研究旨在评估两种不同类型的插入式耳塞的舒适度以及耳塞实现的衰减水平。衰减水平通过市售的耳塞适配测试系统获得，舒适度评分通过问卷调查获得。主要研究目标是确定听力保护器的舒适度是否与测量的衰减值相关。线性混合效应模型为舒适度和衰减之间的反比关系提供了证据。
