The occurrence of noise-induced hearing loss (NIHL) can be detrimental to the future careers of student musicians. Few studies have focused on the noise exposure of student musicians within an indoor pep band as they performed during university basketball games. The purpose of this longitudinal study was to assess: (a) the status of noise dosages acquired via personal noise dosimeters from two pep band players as they performed over nine men's basketball games spanning three seasons, (b) perceived effectiveness of earplugs on the primary participants, and (c) the status of all band members' (n=72) knowledge of hearing loss and hearing loss prevention. The noise dosages accrued by primary participants in each game over the three seasons greatly exceeded the National Institute for Occupational Safety and Health's (NIOSH) recommendation regarding safe daily noise exposure time. Participants occasionally reported that the earplugs did not provide sufficient protection from noise or contributed to communication and intonation issues. Questionnaire responses from band members demonstrated a mild deficiency in hearing loss knowledge. Two-thirds of pep band members reported that they did not always wear hearing protection at pep band functions. Exceeding standard noise dosage recommendations without hearing protection potentially leaves these individuals at a high risk for permanent hearing loss.
噪声性听力损失（NIHL）的发生可能会对学生音乐家的未来职业发展产生不利影响。很少有研究关注学生音乐家在大学篮球比赛期间于室内助威乐队表演时所遭受的噪声暴露情况。这项纵向研究的目的是评估：（a）在三个赛季的九场男子篮球比赛中，两名助威乐队成员佩戴个人噪声剂量计所获得的噪声剂量状况；（b）耳塞对主要参与者的感知效果；（c）所有乐队成员（n = 72）对听力损失及听力损失预防的了解情况。在三个赛季的每场比赛中，主要参与者累积的噪声剂量大大超过了美国国家职业安全与健康研究所（NIOSH）关于安全每日噪声暴露时间的建议。参与者偶尔报告称，耳塞无法提供足够的噪声防护，或者会导致沟通和音准问题。乐队成员的问卷调查结果显示，他们在听力损失知识方面存在轻度欠缺。三分之二的助威乐队成员报告称，他们在助威乐队活动中并非总是佩戴听力保护装置。在没有听力保护的情况下超过标准噪声剂量建议，可能会使这些人面临永久性听力损失的高风险。
