La charge vocale

This article is dedicated to vocal loading, defined as the amount of phonation over time, primarily determined by the duration, the sound pressure level and the pitch of vocalizations. The impact of vocal loading depends on the physiology of each individual, but also on environmental factors, such as background noise and acoustics. Particularly adapted tools for quantifying voice use in daily life are the voice dosimeters or voice accumulators. Such devices have been developed and tested over the last decades, and provide data on vocal behaviour over an entire day of normal activities. From a clinical point of view, we will discuss how to take into account vocal loading for voice treatment. Finally, we will present the benefits of voice amplification and vocal rest in order to reduce vocal load.
