Subjective Evaluation of Stage Acoustics with the Alteration of the Sound Pressure Level of Reverberation

Abstract

The subjective experiments on professional musicians using the four channel real-time convolution system were conducted to investigate the effect of reverberant sound pressure level (Lrev) for stage acoustics. The strength of Lrev was changed to 2dB steps to investigate the optimal strength for ease of performance and the subjective questionnaire survey was conducted to investigate the effect of subjective factor by Lrev. From the experimental results, a specific strength of Lrev is related to ease of music performance. Loudness and directivity are highly correlated.
