Abstract
En este proyecto se desarrollan un conjunto de soluciones para mejorar la audición de personas con disfunciones auditivas con pérdidas de audición en un rango de frecuencias determinado, como la presbiacusia y la hipoacusia, usando procesado no lineal de la señal de voz. La mayoría de los audífonos que se comercializan en la actualidad, están basados en la amplificación de todas las frecuencias provocando efectos indeseados y molestos como los chasquidos, acoplo de otros sonidos, ecos y reverberaciones. El objetivo de este proyecto consiste en valorar diferentes métodos elementales de procesado que solucionen los problemas de audición, para mejorar la inteligibilidad y la calidad de la audición. La valoración se ha realizado a través de diferentes pruebas con personas con problemas de audición. Para ello, se ha desarrollado la aplicación de audiometría y otra con los diferentes métodos desarrollados en este proyecto. Por último, se ha discutido sobre el compromiso entre la mejora auditiva y la conservación de la inteligibilidad. ________________________________________________________________________________________________________________________________
In this final project some solutions have been developed to improve people’s audibility with hearing loss, for example, hearing loss in a determinated frecuency range like presbycusis and hypoacusis, using non-linear processed of voice signal. Actually, most hearing aids sold are based on amplification of all frequencies. It causes annoying effects as clicks, coupling of other sounds, echoes and reverberations. The aim of this project is to value different elementary methods of processed of the signal which solving hearing problems to improve intelligibility and the quality of hearing. The valuation has been realized with several tests to persons with hearing loss. So, an application of audiometry and program application with different methods have been developed. Finally, it has been argued about the relation between audibility and intelligibility.
