Development of a Measurement System of Binaural Acoustic Parameters

This work is about the development of a system for the recording of holophonic sound and the obtaining of binaural acoustic parameters that characterize the spatial perception of sound. At the first part, the implementation of a prototype of a low cost acoustic mannequin, head and torso simulator (H...

At the first part, the implementation of a prototype of a low cost acoustic mannequin, head and torso simulator (HATS), is presented, to which its anthropometric characteristics and frequency responses were analyzed. The second part describes the developed algorithms to process the data measured through the HATS. Finally, some results calculated with the developed system are shown, and compared with those obtained through a commercial software. The applications of the developed measurement system are several, among them can be mentioned: the recording of 3D sounds, the calculation of subjective parameters in room acoustics, or the measurement of noise doses to assess the hearing damage of people exposed to noise through headphones. Este trabajo trata del desarrollo de un sistema destinado al registro de sonido holofónico y a la obtención de parámetros acústicos biaurales que caracterizan la percepción espacial del sonido. En la primera parte se presenta la implementación de un prototipo de maniquí acústico de bajo costo, simulador de cabeza y torso (HATS), al que se le analizaron sus características antropométricas y sus respuestas en frecuencia. En la segunda parte se describen los algoritmos desarrollados para procesar los datos medidos a través del HATS. Finalmente se muestras algunos resultados calculados con el sistema desarrollado y se los compara con los obtenidos mediante un software comercial. Las aplicaciones del sistema de medición desarrollado son varias, entre ellas pueden mencionarse: el registro de sonidos 3D, el cálculo de parámetros subjetivos en acústica de salas, o la medición de dosis de ruido para evaluar el daño auditivo de las personas expuestas a ruido a través de auriculares. application/pdf text/html http://elektron.fi.uba.ar/index.php/elektron/article/view/79 10.37537/rev.elektron.3.2.79.2019 spa FIUBA http://elektron.fi.uba.ar/index.php/elektron/article/view/79/134 http://elektron.fi.uba.ar/index.php/elektron/article/view/79/131 http://elektron.fi.uba.ar/index.php/elektron/article/downloadSuppFile/79/46 Copyright (c) 2019 Nilda Vechiatti http://creativecommons.org/licenses/by-nc-nd/4.0 Elektron; Vol 3, No 2 (2019); 75-83 Elektron; Vol 3, No 2 (2019); 75-83 2525-0159 HATS; acoustic mannequin; impulse response; binaural measurements HATS; maniquí acústico, respuesta impulsiva; mediciones biaurales Development of a Measurement System of Binaural Acoustic Parameters Desarrollo de un sistema de medición de parámetros acústicos biaurales info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion http://repositoriouba.sisbi.uba.ar/gsdl/cgi-bin/library.cgi?a=d&c=elektron&d=79_oai
