Hearing impaired aid and sound quality improvement using bone conduction transducer

摘要

The project aim is to design a smart earplug system integrated with non-invasive bone conduction technique which is capable of doing some advanced audio processing to provide voice enhancing, noise filtered audio for the hearing impaired people. People with hearing loss problem, often use low quality analog hearing aids, which are nothing but a simple analog audio amplifier or a passive audio reinforcement system. They are generally less flexible and are simply designed to gather sound energy and direct it into the ear canal at higher volumes. But with the availability of miniature microphone sensors and extremely low power digital signal processors, hearing aids can be constructed with audiometric and cognitive intelligence that matches the hearing loss, physical features and lifestyle of the wearer, thus delivering more value and benefit for the hearing impaired person. The system is also designed to work as an embedded music player, a life activity tracker and a smartphone companion. It can even read the SMS that is just received on your smartphone into your ear.
