Resumen:
Hearing impairments are conditions that affect a high percentage of the Society. Although there are devices that improve the quality of life for people with these problems, they tend to be expensive and not to fulfill the user requirements. This work focuses on a study and implementation of a spectral compression algorithm, whose goal is to spectrally map the sounds to let a person with a specific hearing condition perceive them. The algorithms are implemented on a low-cost hearing aid device based on the dsPIC33EP512MU810 of Microchip. Subjective experiments using a hearing impairment simulator are done in order to validate the study. Finally, experimental measurements are carried out to analyze the performance of the implemented hearing aid device.
