Search

The purpose of this study was to quantify the relationships between voice parameters and room acoustics. A comprehensive literature search was conducted using PubMed/MEDLINE, Science Direct, and Scopus. Several terms regarding self-reported vocal parameters (vocal fatigue, vocal effort, vocal load, and vocal comfort), as well as possible variants, were included in the search. Also, we included different terms related to room acoustic parameters, such as reverberation time, noise conditions, decay times, room sizes, among others. Finally, a focus group of four experts in the field (current authors) worked together to make conceptual connections and quantify the proposed relationship. In total, 26 publications met the criteria for inclusion. The occurrence and frequency of the most common parameters in the literature are presented, and a quantitative summary of their relationships are reported. The most common journals and proceedings that may be involved in this subject are also pointed out. Through a comprehensive literature search, the most relevant parameters reported are Sound Pressure Level and self-reported vocal assessments for voice parameters, and reverberation time and/or noise conditions for room acoustics. These relationships are quantified and reported while maintaining the concepts as stated in the original articles and outlining their similarities.
