Acoustical studies of the singing voice adapting to the acoustic environment

歌唱的声音受演唱场所声学因素的影响-我们定义了声学环境。为了在各种声学环境中有效地发声，歌唱者的主观歌唱感觉有助于控制歌唱声音。通过以下实验，我们描述了歌唱声音对声学环境的适应.歌唱的主观感觉和歌唱的声音：我们通过（1）对听众的问卷调查和（2）使用喉纤维镜观察喉部，实验了歌手根据两种不同的主观感觉给出的两种歌唱声音之间是否存在客观差异，结果表明：歌唱的主观感觉引起了喉的形态和歌唱声音的音色的变化.声学环境和歌声：通过对四位歌唱家在三种不同声学环境中的歌唱声进行录音，通过（1）对四位歌唱家的问卷调查，（2）对歌唱声的差异性认知问卷，（3）对所有歌唱者的所有歌唱声音进行声学分析，从实验（1）的结果中我们发现所有歌唱者都受到声学环境的影响，他们试图适应每一个环境，同时保持各种感官。（2）和（3）的研究结果表明，在回声太强的环境中，歌唱者更难控制音高，这些研究结果表明，进一步研究歌唱声音与声学环境之间的关系，将有助于歌唱的学习和教学。

The singing voice is affected by acoustic factors of the place to sing - we defined the acoustic environment. In order to sing with efficient vocalizattofl in every acoustic environment the singer's subjective sense for singing contributes to control of the singing voice. Through the following experiments we describe the adaptation of the singing voice to the acoustic environment.1. The subjective sense for singing and the singing voice : We experimented whether or not there were the objective difference between two kinds of singing voices given by a singer depending on two different subjective senses through (1) a questionnaire to listeners and (2) an observation of the larynx using a laryngeal fiber scope, and an acoustic analysis of these singing voices.The results showed that the subjective sense for singing caused changes to the shape of the larynx and to the timbre of the singing voice.2. The acoustic environment and the singing voice : Recording four singers' singing voices in three different acoustic environments, we investigated the adaptation of singing voice to the environments through (1) a questionnaire to four singers, (2) a questionnaire on recognition of the difference of their singing voices, and (3) an acoustic analysis of all singing voices of all singers.From the results of experiment (1) we found that all singers were affected by the acoustic environment, and they tried to adapt to each environment keeping various senses at the same time. The results of (2) and (3) showed it was more difficult for singers to control the pitch in the environment with too much echo.The results of these studies suggest that father study about relationship between the singing voice and the acoustic environment will be useful for learning and teaching singing.
