Diseño y construcción de un dispositivo acústico para la reducción de ruido generado por presión de aire durante el proceso de grabación binaural

Binaural 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
