- PublicaciónAcceso abiertoBase de datos web de filtros para compensar la respuesta en frecuencia de audífonos mediante reproducción binaural(2019) Vásquez Garzón, Sebastián; Hormiga Leal, Juan PabloThe binaural sound is based on recording sounds emulating the conditions of how the human ear listens, through the audio you get a quite enveloping panorama using one of our senses as the ear; Once interpreted by the brain the binaural audio is identified or located from its source of reproduction or execution since one of the characteristics of binaural audio is its spatial location or its movement with respect to the listener, For its faithful reproduction the binaural audio needs conventional systems to synchronize the hemispheres of the brain and it is necessary that the listener hears through the use of hearing aids. Since earphones are required for the use of binaural audio, due to their electroacoustic characteristics, not all hearing aids are properly coupled to the use of binaural audio due to an insufficient equalization in their system, therefore, due to the lack of compensation in the headphones This research carries out a study in different references of low and high range hearing aids, where a hearing aid equalization method is evaluated to compensate the alterations in the frequency response of headphones by designing an inverse filter for binaural signals by the method of Masiero
- PublicaciónAcceso abiertoDesarrollo de una Producción Musical (EP) Basada en la Comparación de 4 Técnicas que Simulan Captura Binaural.(2009) Arenas Rodríguez, Fabian Alejandro; Quishpi Bastidas, Santiago Isaías; Silva, Carlos; Carrillo, AejandroEste proyecto se enfoca en el estudio comparativo de cuatro montajes que asemejan capturar binaural, para determinar las ventas y desventajas de cada uno, al ser evaluados en distintos aspectos psicoacústicos aplicados a la producción musical, demostrando así cuál de ellos presenta el mejor comportamiento acorde con los resultados del análisis realizado.
- PublicaciónAcceso abiertoDiseño y construcción de un dispositivo acústico para la reducción de ruido generado por presión de aire durante el proceso de grabación binaural(2019) Chaparro Valencia, David Alejandro; Berrío Bernal, Juan DavidBinaural audio recording is one of the new fields of sound engineering worldwide, which focuses on recording or capturing audio samples through the binaural technique; This can be applied using a mannequin head with transducers (microphones) located in your ears, or in a more natural way, locating the transducers in the ears of a human being, to take advantage of their morphology and texture, so that the samples recorded have the greatest effect of spatiality as a person would hear it. Since the function of a microphone is to transduce energy from an acoustic field to an electric field, any change in pressure that is generated in the acoustic field will be recorded by the microphone, independent if the pressure change is due to a sound wave or the constants fluctuations that the air possesses. This is why the following document will focus on analyzing how the impact of air flow (wind) on binaural recordings can be mitigated; for this, it is intended to obtain a source of wind generation that is silent and that can produce a wind speed of at least 5 m / s. After this, a series of absorbent materials typical of the field of architectural acoustics and electroacoustics will be used to develop a device based on which it is efficient, counteracting the wind phenomenon and which keeps the sound sample frequently
