摘要

简介布拉玛里呼吸法（BP）是一种瑜伽呼吸法，它能发出类似大黄蜂嗡嗡声的持续振动音调。由于 BP 涉及持续音调的呼吸和嗡嗡声，因此假设它对改善个人的嗓音质量有影响。然而，支持这一假设的研究还很匮乏。目的：本研究旨在探讨 BP 对准歌手嗓音特征/质量的影响：方法：参与者包括 30 名健康的准歌手，年龄在 18-35 岁之间，在印度卡纳塔克邦的音乐学校就读。所有参与者都接受了血压测量。分别在 BP 练习的第 0 天和第 30 天采集了参与者的声音记录。通过声学分析，从 MDVP 程序中获得 AVQI 及其组成参数和声音参数：在 AVQI 及其组成参数中，Cepstral peak prominence-smoothed、Slope LTAS 和 Tilt LTAS 在 BP 前后有显著差异。MDVP显示，BP练习前后的震颤测量结果有明显差异：本研究结果表明，BP 对准歌唱家的嗓音特征有积极影响，并反映在 AVQI 和 MDVP 的客观声学结果参数上。这支持了一种假设，即包含瑜伽呼吸的 BP 将对声乐生理产生有益影响，进而改善这些人的嗓音质量。不过，今后有必要在更大的样本和人群中使用不同的结果测量方法来验证这些研究结果。此外，未来的研究还需要验证 BP 在改善发音障碍患者的发声质量和发声效率方面的功效。

A Preliminary Study on the Effect of Bhramari Pranayama on Voice of Prospective Singers

Introduction

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.

Aim

Current study was taken up to explore the effect induced by BP in the voice characteristics/quality of prospective singers.

Method

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.

Result

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.

Discussion

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.
