Hi, Please excuse the extreme ignorance of the question I am about to pose. I am fairly handy, but have little in the way of electronics know-how.
A friend of mine is a children's speech therapist who recently had her therapy room remodeled. There is a need for the parents who are observing their children to be able to hear the therapy session. The parents are outside of the room observing through a one-way mirror. No one else should be able to hear what is going on in the room (wireless systems that could be 'overheard' would not be acceptable). Any equipment in the room should be silent and unobtrusive so as not to disturb the session.
One idea we had is to have a microphone put in a wall with a grill over it. From the outside, the parents could perhaps plug headphones into some kind of jack in the outer wall. Does this sound feasible? What would it take to make this system work? I presume the microphone would be attached to an amplifier and that would be wired to the jack.
Any other suggestions? If you could be as specific as you can with model numbers and suppliers that would be great.
Thanks for your help and suggestions.
