Brass bands that include wind instruments are heavily affected by rules established during the pandemic. The aim of this experimental work was to assess the aerosols emitted through different wind instruments. The Aerodynamic Particle Sizer (APS) was used to measure the aerosols emitted and transmit those characteristics to a database. The results revealed that the dynamic level at which a note is produced, regardless of whether it is a clarinet, trumpet, or bassoon, significantly changes in aerosol concentrations emitted. Specifically, if there is a higher dynamic level, an increase in emissions of particle concentration will occur by comparing the levels piano, mezzo forte, and forte. These aerosols are produced with a diameter of approximately 0.8 μm, except for the Navarra bagpipe, which has a diameter of 1.8 μm. In addition, this last instrument is the one that emits more particles every second, reaching a value five times larger than that with two reeds, such as the bassoon. Staccato and legato are two well-known techniques among musicians that help in articulating a musical piece. The difference between the two methods in terms of the concentration of the number of particles is not remarkable and is almost negligible.
包含管乐器的铜管乐队受到疫情期间制定的规定的严重影响。这项实验工作的目的是评估通过不同管乐器排放的气溶胶。使用空气动力学粒径分析仪（APS）来测量排放的气溶胶，并将这些特征传输到数据库中。结果表明，无论演奏的是单簧管、小号还是巴松管，产生音符时的动态水平都会显著改变气溶胶的排放浓度。具体而言，如果动态水平较高，通过比较钢琴、中强和强的水平，颗粒浓度的排放量将会增加。除了直径为1.8微米的纳瓦拉风笛外，这些气溶胶的直径约为0.8微米。此外，最后这种乐器每秒排放的颗粒最多，其值比双簧管类乐器（如巴松管）高出五倍。断奏和连奏是音乐家中广为人知的两种技巧，有助于清晰地演奏一段音乐。这两种方法在颗粒数量浓度方面的差异并不显著，几乎可以忽略不计。
