This type of damage is from heavy duty ultrasound, infrasound at 164dB. You can direct a sine wave at a tree and burn it until the inside of the tree is burned, killing the tree. My dogs have been shot with triangle waves set at 164 decibel, killing and maiming them. I was shot in the right hip, leaving an infected mess that took several months to heal.
