If you want a first hand experience in shock gobbling....ask a turkey raising farmer too see his penned gobbler flock. You'll hear that they will shock gobble to almost any sound. But be careful not to have any young kids sneak into the turkey pen, because the turkeys might peck them to death --- which happened in Maryland to a small infant that crawled into a turkey pen --- about 50 years ago.
