Hero999 Banned Sep 10, 2008 #2 Infrasound is below 20Hz. Audiable sound is below 20kHz which can be detected with a cheap electrect microphone. The MCE-200 is a simple electect which is useless above 16Khz and below 20Hz. Similar componenets can be bought from places like RS Components, Maplins and Rapid electronics. You haven't filled your location in so we have no idea of what stores exist near you. Last edited: Sep 10, 2008
