 1992-Studies are under way examining the viability of using acoustics as a less-lethal weapon. Acoustic technology devices. The inner ear regulates spatial orientation; thus, saturation by high-intensity sound can cause disorientation in people..In the 1970's, the Russian government developed a highpowered, very-low-frequency (VLF) modulator that could cause general physical discomfort, and increasing the power could induce nausea, vomiting, and abdominal pains . The Long Range Acoustic Device (or LRAD) is a crowd-control and deterrent sonic weapon developed by the American Technology Corporation.The device.The LRAD is capable of transmitting spoken words as well as a shrill high-pitched warning tones. It has been effectively deployed in Iraq, in Afghanistan,and by some large police departments in the United States for use during mass demonstrations and other public disorder situations.

Active-Denial Devices Active-denial technology uses electromagnetic energy to rapidly heat up an approaching subject’s skin and ultimately deter the subject from advancing on a particular position. Active-denial technology uses a transmitter to send a narrow beam of 95-GHz millimeter waves toward a specific subject or group. Traveling at the speed of light, the energy reaches the subject and penetrates less than 1/64 of an inch into the skin, heating it to 130 degrees in less than two seconds. This produces an intense burning sensation that stops when the transmitter is switched off or when the individual backs away
Critical Issues in Policing Forum brought together police executives who had introduced this new technology. Chief James Corwin, Kansas City (MO) Police Department; Chief Harold Hurtt, Houston Police Department; Chief Albert Najera, Sacramento Police Department; and Chief Darrel Stephens, Charlotte-Mecklenburg (NC) Police Department, all offered their perspectives of other more exotic acoustic deterrents that aim voices directly at an individual 's auditory cortex .The voice only the target can hear causes  disorientation and panic as the  disembodied voice that bypasses the ear is meant to mimic schizophrenia and is often enough to incapacitate the most hostile criminal with no use of possibly lethal force   -Janet Reno
