Active Noise Cancellation Techniques to Enhance Audition in Noisy Cities

Abstract

It is proposed in this research some suggestions and applications to enhance and care of the hearing health in noisy cities, such as for example, the noise that is caused by traffic, engines from factories and imprudent behavior from drivers and street sellers (as it happens in Peruvian cities). In this research, it was analyzed many techniques according to propose enhancement of the health audition by engineering analysis of the noise cancellation and advanced sensors/actuators (microphones and loudspeakers) that were based in nanostructures, because to achieve this objective. Therefore, it is expected that this research could be a support for institutions, which need technical analysis results, regarding to study the necessity to care the hearing health in noisy cities, such as for example, many hospitals, homes, universities and schools that are located near noisy avenues cannot get attenuation of noise, if there are not noise cancellation systems to care the hearing health.
