Effect of reverberation time on vocal fatigue

Pasquale Bottalico, Simone Graetzer, Eric Hunter

Vocal effort is a physiological entity that accounts for the changes in voice production that occur as vocal loading increases. It has been quantified in terms of Sound Pressure Level (SPL). In previous research, it has been shown that prolonged vocal effort can lead to vocal fatigue. An experiment was conducted to measure the effect of reverberation time on vocal fatigue, by means of an evaluation of variation in vocal effort over time. Twenty subjects were recorded while reading a text in anechoic, semi-reverberant and reverberant rooms in the presence of babble noise. Within-subject variation in SPL was measured per task. It was found that SPL tended to increase less over time in the semi-reverberant environment than in the anechoic or reverberant environments. This finding suggests that subjects experienced less vocal fatigue in the semi-reverberant environment.
