Does TI have a solution for hearing aids design ?

Philippe Pango

Hello there,

What is TI's suggestion for a one chip solution to build a digital hearing aid ? I am talking about a DSP with an embedded codec (at least one A/D but preferrably two A/Ds to support dual microphones ), enough on-board RAM and EEPROM to code adaptive algorithms such as noise reduction, FFT, etc. Is there an application note describing such design ? So far, I have found a separate audio codec (AIC11) and separate DSP, but no one chip solution.

Thanks

Hi,

We know there is a need like your application. So we're under consideration. In the mean time you can try out with C5535ezDSP http://www.ti.com/tool/tmdx5535ezdsp?DCMP=dsp-c5000-c553x-110830&HQS=dsp-c5000-c553x-pr-sw.

Regards,

Such a power-critical application would need ASIC design rather than general-purpose DSP. Neither TI nor other DSP manufacturers can help you.

Dear Hyun

I seek a DSP chip and associated software for the development of a simple digital hearing aid (not directional mic).

Please advise me on your current range.

Yours,

This SDK board looks very interesting. Can I create say a 10 band equalizer? Or maybe a parametric filter? My Audiologist said the hearing aids cost $4500. It is beyond my budget. I would rather develop my own. I have tried the Cypress Psoc family. But I can't get the multi band equalizer.

Thanks,

Philip
