Bhramari Pranayama (BP) is a yogic breathing technique that involves producing a vibrating constant pitch sound emulating the buzzing of bumblebee. Since BP deals with breathing and humming in the sustained pitch, it is hypothesized that it can have implications for improving voice quality in individuals. However, there is a dearth of research available to support this assumption. Further, there are no published reports on the effect of BP on voice quality in prospective singers group.
Current study was taken up to explore the effect induced by BP in the voice characteristics/quality of prospective singers.
The participants included 30 healthy prospective singers in the age range of 18-35 years who were attending music schools within the state of Karnataka, India. BP regimen was demonstrated to all individuals. The voice recordings of the participants were obtained on day 0 and day 30 of BP practice. Acoustic analysis was performed to obtain AVQI and its constituent parameters and voice parameters from the MDVP program.
Among the AVQI and its constituent parameters, Cepstral peak prominence-smoothed, Slope LTAS, and Tilt LTAS showed significant differences before and after BP. MDVP showed a significant difference in tremor measures before and after the practice of BP.
Results of the present study indicated positive effects of BP on the voice characteristics of the prospective singers and it is reflected in objective acoustic outcome parameters of AVQI and MDVP. This supports the assumption that BP which involves yogic breathing will have beneficial effects on vocal physiology in turn leading to improved voice quality in these individuals. However, it is of future interest to validate these findings on larger samples and populations with different outcome measures. Also, future studies are warranted to verify the efficacy of BP in improving vocal quality and vocal efficiency of individuals with dysphonia.
Bhramari Pranayama（BP）是一种瑜伽呼吸技巧，涉及产生模仿大黄蜂嗡嗡声的恒定音高的振动声。由于 BP 涉及呼吸和持续音高的哼唱，因此假设它可以对改善个体的语音质量产生影响。然而，目前还没有研究支持这一假设。此外，没有关于 BP 对预期歌手群体语音质量影响的已发表报告。
本研究旨在探讨 BP 对预期歌手的声音特征/质量的影响。
参与者包括 30 名年龄在 18-35 岁之间的健康预期歌手，他们正在印度卡纳塔克邦的音乐学校就读。向所有人展示 BP 方案。在 BP 实践的第 0 天和第 30 天获得参与者的声音记录。进行声学分析以从 MDVP 程序获得 AVQI 及其组成参数和声音参数。
在 AVQI 及其组成参数中，Cepstral 峰值突出度平滑、LTAS 斜率和 LTAS 倾斜在 BP 前后显示出显著差异。BP 实践前后，MDVP 的震颤测量值存在显著差异。
本研究结果表明，BP 对预期歌手的声音特征有积极影响，这反映在 AVQI 和 MDVP 的客观声学结果参数中。这支持了这样的假设，即涉及瑜伽呼吸的 BP 将对声乐生理学产生有益影响，从而提高这些个体的语音质量。然而，未来需要在更大的样本和不同的结果测量人群中验证这些发现。此外，还需要进一步的研究来验证 BP 在改善嗓音障碍个体的语音质量和发声效率方面的功效。
