Abstract The directional index of sound sources such as musical instruments is an important input for the current methods of room acoustics simulations. In this article, the uncertainty associated with the directional characteristics of musical instruments across each frequency band. First, the directional factors in third octave bands are estimated from a dataset of measurements…

Abstract The sound strength parameter G is one of the most important objective parameters related to the acoustical quality of concert halls, opera houses, and chamber music hall. G at mid frequencies is highly correlated with the acoustic quality reported by music conductors and subject with musical training. Measuring this parameter requires a calibrated sound…

Presented at the 19th Working Meeting on Information Processing and Control, 2021 Abstract The state of the art on measurements of room acoustics parameters is based on an as omnidirectional as possible sound sources. Although these measurements are still the current standard, criticism regarding the standard directivity tolerance and the suitability of omnidirectional sources has…

Presented at the 23rd International Congress on Acoustics, 2019 Abstract Concave surfaces are know to focalize or diffuse sound depending on the curvature and the source position regarding the surface. Spherical rooms are frequently found as theoretical cases in the literature. In this work, results from models and measurements of the acoustics inside a 7-m-diameters…

Presentado en las IV Jornadas de Comunicación de Proyectos de Investigación y de Creación del Gabinete de Estudios Musicales, 2018 Resumen Desde los inicios de la acústica de salas como una rama científica de la acústica los investigadores del área han desarrollado descriptores acústicos mesurables que puedan estar correlacionados con las características constructivas de las…
