Abstract

Noise pollution does harm to urban residents, so we design an unpitched sound generator using masking effect in psychoacoustics, which can conceal or compete with ambient noise, in order to help people to be more concentrate. It can also generate warning noise according to the speed of electric bikes to improve driving safety. Experiment shows that natural noise has the best masking effect, while Meaningless noise has the highest masking efficiency. This sound generator we design is extensible and easy-to-use, and has high value, providing methods approach to compete noise interference and use noise to enhance security for a practical application.
