To evaluate musicians' personal attenuation and perceptions of three types of hearing protection devices (HPDs): formable foam earplugs and both non-custom and custom versions of uniform attenuation earplugs (UAEs) marketed to musicians.
A mixed-methods approach was used to evaluate the HPDs. Audiometric testing obtained hearing levels at baseline and with each HPD across frequencies (125-8000 Hz) to determine personal attenuation ratings and uniformity of attenuation. Participants completed surveys over six months regarding how often they used the HPDs and their perceptions about wearing them.
Twenty-four musicians were recruited to participate.
Substantial variability was observed in the attenuation achieved among participants for each HPD type, but custom UAEs provided the most consistent attenuation across frequencies. Participants' HPD preferences were influenced by multiple factors including personal instrument and specific activity. Custom UAEs were most frequently used but usage rates continually decreased over the 6-month period.
Fit-testing is important to determine fit and sizing. Combining information on the effectiveness of HPDs with musicians' opinions about wearing them can inform recommendations for which types may be the most effective and feasible options for reducing sound exposures.
评估音乐家对三种听力保护装置(HPDs)的个人衰减和感知:可成形泡沫耳塞以及向音乐家推销的两种非定制和定制的均匀衰减耳塞(UAEs)。
采用混合方法评估 HPDs。听力测试在基线和每种 HPD 下在频率(125-8000Hz)上获得听力水平,以确定个人衰减等级和衰减均匀性。参与者在六个月内完成了关于他们使用 HPD 的频率以及对佩戴它们的看法的调查。
招募了 24 名音乐家参与。
在每种 HPD 类型中,参与者获得的衰减量存在很大差异,但定制 UAEs 在整个频率范围内提供了最一致的衰减。参与者对 HPD 的偏好受到多种因素的影响,包括个人乐器和特定活动。定制 UAEs 是最常用的,但在 6 个月的时间里,使用率持续下降。
适配测试对于确定适配性和尺寸很重要。将 HPDs 的有效性信息与音乐家对佩戴它们的看法结合起来,可以为减少声音暴露提供最有效和可行的选项提供建议。
