I guess I'm overstating the quality expected by "pin drop". I'm sure they'd be happy with decent audio.
Right now I have the speaker mounted on the ceiling and it seems to pickup ok, but you can hear a constant background noise. Almost like its picking up the sound of the fidges and heating system. You can hardly hear what anyone is saying.
I know that on higher end audio equipment, there's filtering done to quiet the abient noise. I was just wondering if they made something that would do a good job, without spending thousands of dollars.
