- 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
- PublicaciónAcceso abiertoEstrategias bioclimáticas para mejorar el confort térmico en viviendas medianeras en el centro de la ciudad de Quibdó(2019) Quesada Cuesta, Alex Emiro; Sierra Uribe, Andrés Felipecurrently with new construction features in their groupings; which allows to identify that more than 80% of them are party-wall conditions, and the predominant morphology are rectangular properties. This region, due to its location within the Equator and the tropic of Cancer, is defined by climatic conditions of low wind intensity, part¬ly cloudy skies, relatively high temperatures and humidity. The above are characteristics from the humid warm climate, the morphology of the pro¬perties, the conditions of the party wall, entail that this construction typology presents many hours of thermal discomfort throughout the year which has encouraged the massive installation of mechanical cooling systems, which has had an effect on the increase of energy consumption. This Project seeks to implement bioclimatic stra¬tegies that help on the improvement of the ther-mal comfort levels inside houses units located downtown Quibdó, transforming this document into a design guide for new implementations of these characteristics; to help on the improve-ment of the quality of life of people, to decrease the energy consumption; and therefore on the negative impact on the planet
