From My Central Jersey.com:  What's that sound? NJ ghost hunters keep listening for signs

They may not see dead people — but they certainly can hear or sense them.
As Halloween approaches, several area ghost hunters and paranormal experts will be making appearances to explain their craft and offer proof of what they say are real-life hauntings.
Garden State paranormal experts these days are about as ubiquitous as ghost-hunting television shows, including the long-running “Ghost Adventures” on the Travel Channel and “Ghost Hunters” on Syfy.
“We’re tripping over each other,” said Tom Petuskey, 71, an East Brunswick resident and member of Scope NJ, a paranormal research group founded in 2007.
“We are looking for scientific confirmation of paranormal events,” he said. “One of the things we try to do is see if there are natural causes for what’s happening.”
Scientists might balk at paranormal researchers’ techniques, but these ghost buffs use real equipment and adhere to what could be considered ghost-industry standards.
One of their favorite tools is a device found at any electronics store: an audio recorder.
Serious ghost hunters might shell out hundreds or thousands of dollars for complex and highly sensitive microphones and recording hardware. But Charles “Chuck” Lehman, 47, of Monroe makes do with a simple $70 recorder and free audio software Audacity.
The recorders are supposed to pick up what is known as electronic voice phenomena, or EVPs, which cannot be heard by the people in the room.
EVPs may be of ghosts whispering words like “hello,” or phrases like, “get out of here!”
Lehman, an amateur ghost hunter who likes to capture EVPs at historic battlefields and cemeteries, compares them to dogs picking up low frequency sound waves. He has clips of EVPs from cemeteries in Jamesburg and Bound Brook on his website, www.chucksghosts.com.
The ghost hunters say they don’t manipulate the recordings except to enhance the sound.
Petusky, whose group posts its evidence from investigations at www.scopenj.com, said in one instance his team couldn’t make out a garbled EVP from an investigation at a 1919 Manville home.
