Lmic
The Lmic (pronounced “el mike“) is an easy-to-use,
low cost, electronic listening stick and ground micro-
phone combined. It is ideal for general leak sound-
ing operations and can be fitted with either a tripod
foot (for use as a ground microphone) or probe rods
(for sounding at fittings or in soft ground).
The control unit is hand-held with a “trigger” opera-
tion and a volume/sensitivity rotary control. An LED
indicates operation and battery status. It can be
used to confirm the position of underground leaks
audibly from ground level; sound pipe fittings;
penetrate soft ground to listen for leaks or carry out
traditional acoustic surveys.
