we need a dsp professional ,long time ,good price (finally) Hi, we are using a algorithm ,which do noise reduction ,fft,etc ,it's working ok ,however ,it seems the noise reduction not so obivously, it seems to have big background noise. ok,below are our full requirements : we are developing hearing aid based on RSL10 ,it has arm coretex m3 mcu and lpdsp32 DSP .we use DSP to do noise reduction ,equalizer,etc first step is : build a good noise reduction .our DSP is LPDSP32, we have our noise reduction on LPDSP32 ,seems not good enough we need use LPDSP32 ,if one LPDSP32 not strong enough ,we will have 2 LPDSP32s

Hello, There are two major sources of noise in hearing aid devices, background noise and internal echo. There are different ways to tackle with each such as beamforming and adaptive filtering (echo canceller). Some of these techniques are quite complex. I am not sure which noise problem you are encountering in your design but this could be a simple or a complex task to solve. First I need to consider your design in detail and see how you have suppressed the noise. Then I will propose you a better method to suppress the noise. Anyway, I am a professional DSP engineer and have several years of experience. I am also a professional embedded designer and can implement the algorithm in your ARM processor (assembly C/C++). I can share more details about my approach in the chat. Thanks.
