  • 摘要:In recent years, FPGAs (field-programmable gate arrays) have become increasingly attractive as sound/speech processing engines, sometimes used alone and sometimes in conjunction with a processor chip. When we detect sounds, or noise, our body is changing the energy in sound waves encoded into nerve impulses which the brain interprets as sound/speech. Sound Waves are produced when the air is mechanically disturbed. A cochlear implant system with Computerized FPGA based speech processing unit is a surgical implantable device which restores some hearing in severely-to-profoundly deaf people when the organ of Corti has not developed or is destroyed by disease or injury to such an extent no comparable hearing can be obtained with a hearing aid. This paper presents how the sound/speech signals processed by Computerized FPGA based speech processing unit and sends the processed information to the brain with implantable system for making auditory sensation.
