【 摘 要 】

Hearing is considered as the most important senses of humans because it connects us to the world always. And the communication between humans are mostly by speaking and listening. So hearing loss can have a significant affect on our life, from our work to our connections and enthusiastic prosperity. A hearing aid is an electro-acoustic gadget, which is intended to increase sound, with the point of making speech more comprehensible. The fundamental task of the hearing aid is to selectively amplify sound signals to such an extent that the handled sound matches ones audiogram. The emerging demand for personalized hearing assistants requires the filter bank to be capable of decomposing the sound waves in accordance with the characteristic of the patients hearing loss. In this review paper, the application of multirate frameworks and filter banks for different procedures in personalized hearing assistants are investigated.
