| Abstract: | With the development of the digital signal processing technology,digital hearing aids have become mainstream products in the acoustic area industry.Considering some problems of shortcoming in its qualities such as real-time performance,size and power consuming,the study constructs a development platform of hearing aid based on microphone arrays to improve auditory perception.The platform uses the TMS320C6747 chip as a core CPU and TLV320AIC32 audio converter for sampling.On the platform,various source localization algorithms have been studied in detail.Furthermore,an improved method is proposed. |
