Previous literature suggests that musical performers may be influenced to some extent by the acoustic environment in which they sing or play. This study investigates the influence of room acoustics on singers' voice production, by analyzing consecutive sung performances of classically trained students in five different performance spaces. The analyzed voice parameters were vibrato rate, extent, and pitch inaccuracy. Nine classically trained student-singers performed the same aria unaccompanied on a variable starting pitch that was consistent between spaces. Variance in vibrato rate and pitch inaccuracy was primarily explained by individual differences between singers. Conversely, the variance attributable to the rooms for the parameter of vibrato extent was larger compared to the variance attributable to the performers. Vibrato extent tended to increase with room clarity (C80) and was inversely associated with early decay time (EDT). Additionally, pitch inaccuracy showed a significant negative association with room support (ST). Singers seem to adjust their vocal production when performing in different acoustic environments. Likewise, the degree to which a singer can hear themself on stage may influence pitch accuracy.
先前的文献表明，音乐演奏者在一定程度上可能会受到他们演奏或演唱的声学环境的影响。本研究通过分析五名不同表演场地的受过专业训练的学生的连续演唱表演，来研究房间声学对演唱者声音产生的影响。所分析的声音参数包括振音率、幅度和音准误差。九名受过专业训练的学生演唱者在不同的表演场地以相同的起始音高演唱无伴奏咏叹调，每个场地之间的音高保持一致。振音率和音准误差的变化主要归因于演唱者个体之间的差异。相反，与演唱者相比，归因于房间的振音幅度的变化要大得多。振音幅度随着房间清晰度（C80）的增加而增加，与早期衰减时间（EDT）呈反比。此外，音准误差与房间支持（ST）呈显著负相关。演唱者在不同的声学环境中表演时似乎会调整他们的发声方式。同样，歌手在舞台上听到自己声音的程度可能会影响音准。
