music is performed with specific drums, which produce loud and low-tone sounds that can potentially lead to hearing risk.
To assess sound pressure levels and hearing safety of musicians who play in groups.
Using a decibel meter, noise exposure was measured in two different groups (group 1 and group 2), which are divided into categories: (group 1 = five categories - junior, free, general a, general b, and master, and group 2 = two categories - adult and child). The calculation of the daily noise dose was based on the Brazilian Occupational Hygiene Standard 01, which establishes the following classification: acceptable dose (between 0 and 50%), above the action level (50 to 80%), uncertain dose level (80 to 100%), and above the acceptable level (more than 100%).
In group 1 categories, the daily noise doses obtained were: junior = 88%; general B = 423%; master = 218%; general A = 370%, and free = 150%. In the adult and children categories of group 2, the results were 127 and 17%, respectively.
musicians are exposed to daily noise doses above the safe level, except for the junior categories in group 1, and the children, in group 2 - which showed daily noise doses at an uncertain dose level, and at an acceptable level, respectively.
音乐表演使用特定的鼓，这些鼓会发出响亮和低沉的声音，可能会导致听力风险。
评估集体演奏的音乐家的声压水平和听力安全性。
使用分贝仪，在两个不同的组（第1组和第2组）中测量噪声暴露，这两个组又分为不同类别：（第1组 = 五个类别——初级、自由、普通A、普通B和大师级，第2组 = 两个类别——成人和儿童）。每日噪声剂量的计算基于巴西职业卫生标准01，该标准规定了以下分类：可接受剂量（0至50%之间）、高于行动水平（50至80%）、不确定剂量水平（80至100%）和高于可接受水平（超过100%）。
在第1组的类别中，获得的每日噪声剂量为：初级 = 88%；普通B = 423%；大师级 = 218%；普通A = 370%，自由 = 150%。在第2组的成人和儿童类别中，结果分别为127%和17%。
除了第1组的初级类别和第2组的儿童外，音乐家每天暴露于高于安全水平的噪声剂量下——第1组的初级类别显示每日噪声剂量处于不确定剂量水平，第2组的儿童则处于可接受水平。
