Electret microphone
Posted: Sun Feb 19, 2012 6:05 pm
Dear Nic,
I am electronically challenged( capabilities are in the medical field) and was hoping you could help me. I have a project in mind and need to know if there is a measurable current in an electret microphone when it is not in use. For instance could one have a programme detecting this current and should the quantity change cause an effect?
If, as I have surmised from my limited knowledge, such a current exists what would affect it? For instance if the air was replaced with a gas would that affect the current?
Your help is very much appreciated.
