Abstract

Introduction and objectives: Acoustic analysis is a tool widely used by professionals related to the study of voice that gives us information from a recording. It has been identified that in investigations carried out today that involve acoustic analysis, the recording process takes place in rooms with different levels of background noise. The objective of this study is to establish whether the acoustic parameter harmonic-to-noise ratio (HNR) varies in relation to the different background noise levels of the premises where the recording is made and recommend a maximum level of background noise.
