Recommend mic and pre-amp? #4

Open atuyosi opened 6 years ago

atuyosi commented 6 years ago

I'm newbie in hearing aid development and aundio I/F.

I bought audio injector, and set up with Raspberry Pi .

I'd like to know the recommended microphone and amplifier (mobile ready).

Also, audio Injector has ECM type mic, is there any problem with this mic?

The recommended mic and our semi-custom pre-amplifier are detailed in the wiki

The problem with the Injector-mic is that it does not record the sound pressure level close to the ear.

Thank you for quick response.

Perhaps I can not get an assembled kit in Japan. I will make a substitute products by referring to the circuit diagram.

Thanks.
