Yakshagana is an India's traditional folk theatre musical dance drama. The purpose of the study is to profile audiological characteristics and document hearing-related symptoms in Yakshagana artists. A cross-sectional study was performed on 96 Yakshagana artists. Participants' demographic data were captured, and audiological evaluations, including high frequency audiometry (HFA), tympanometry, acoustic reflex threshold and transient evoked otoacoustic emission (TEOAE), were performed. The majority of the individuals had minimal and mild hearing loss. The mean scores of pure tone thresholds were greater at 4 kHz and 8 kHz. The majority of the HFA thresholds at 10 kHz, 12.5 kHz, and 16 kHz indicated no responses, which can be accredited to the fact that noise-induced hearing loss (NIHL) first affects the higher frequencies. TEOAE analysis showed a greater percentage of failures in the higher frequencies, particularly at 3 and 4 kHz in both ears, which can be an indicator of bilateral cochlear damage. These findings indicate that Yakshagana artists are at risk of hearing loss due to noise exposure. Hearing evaluation and regular monitoring of hearing thresholds is advisable for this population as it can impact their careers.
雅卡加纳舞剧是一种印度传统民间戏剧音乐剧。本研究的目的是剖析雅卡加纳舞剧艺术家的听力学特征，并记录与听力相关的症状。对96名雅卡加纳舞剧艺术家进行了一项横断面研究。收集了参与者的人口统计学数据，并进行了听力学评估，包括高频听力测定（HFA）、鼓室图、声反射阈值和瞬态诱发耳声发射（TEOAE）。大多数人有轻度和中度听力损失。4kHz和8kHz处的纯音阈值平均得分更高。10kHz、12.5kHz和16kHz处的大多数HFA阈值无反应，这可以归因于噪声性听力损失（NIHL）首先影响高频这一事实。TEOAE分析显示，高频段，尤其是双耳的3kHz和4kHz处，失败率更高，这可能是双侧耳蜗损伤的一个指标。这些发现表明，雅卡加纳舞剧艺术家因接触噪声而有听力损失的风险。建议对这一人群进行听力评估并定期监测听力阈值，因为这可能会影响他们的职业生涯。
