What screening is necessary if I want to protect a domestic-grade electret microphone from the RF coming from a cellphone which is in use?
I sometimes hear radio or TV news broadcasts which still get cellphone interference so I would guess it is not all that easy to provide a reasonale level of screening.
On the other hand, you can get a cheap electret microphone designed to be worn in the ear (as a phone-recording microphone) which is remarkably resistent to cellphone RF.
How do I make a domestic electret microphone capsule with its co-ax microphone cable (cdonsisting of shield and one core) resistent to cellphone RF?
