Im just about to build an intercom ..more specifically.. an intercom by Paul stenning.. its schematics can be found on web ee..the thing is ... im not sure how clear its output will be in the noisy hall during my presentation... so, i was wondering whether anyone has tried building it before...if yeah, could you fill me in on how well it works? whether its voice output is audible, even in very noisy conditions ? or does it suffer from very bad interference?
Thanks
