The system has a microwave generator mounted on a vehicle that transmits millimeter waves that penetrate clothing and excite water molecules, causing a burning sensation.

• Non-lethal sound weapons

  These sound weapons are primarily used for crowd control, military operations, and law enforcement. They include:

  • Acoustic Hailing Devices (AHD)

    The AHD is a sound weapon that broadcasts audible and inaudible sounds over long ranges. It is used to communicate and issue warnings in law enforcement and military operations. The device can relay messages at a distance of 30 km and can produce sounds that can be damaging to the eardrums and cause temporary or permanent hearing loss.

  • Sound cannon

    A sound cannon is a non-lethal sound weapon used for crowd control. It emits loud, concentrated blasts of sound that can cause disorientation and discomfort to disperse crowds. The sound cannon works by focusing sound waves in a particular direction to create an intense sound that can be heard over a large area. It is commonly used by the police, military, and security personnel to control crowds and manage public disturbances.

  • Acoustic weaponry

    These refer to devices that use focused beams of sound to achieve various effects. They are used for personal protection, military, and law enforcement purposes. Acoustic weaponry encompasses a range of devices that use sound waves to communicate, intimidate, or control individuals or groups. This includes Long-Range Acoustic Devices (LRADs), which can transmit messages or warnings over long distances and emit painful, disorienting sounds to disperse crowds or control riots.

How to choose sound weapon

• Intended use

  Determine if the sound weapon will be used for self-defense, law enforcement, military operations, or research. Some sound weapons are better for one thing than another. For instance, ultrasonic sound guns are great for self-defense since they are portable. However, they may not be effective for law enforcement or military operations. On the other hand, long-range acoustic devices (LRADs) are ideal for law enforcement and military operations because they can send clear messages over long distances. Therefore, understanding the intended use of the sound weapon helps one choose the best.

• Range and effectiveness

  Sound weapons have different ranges and effectiveness. For instance, subsonic and infrasonic frequencies can cover long distances but are not audible. On the other hand, ultrasonic frequencies can be focused on a short range. Therefore, if one needs a sound weapon that can affect a large area, it is good to choose one that operates at low frequencies. Conversely, if one needs a sound weapon for a short range, then go for one that utilizes ultrasonic frequencies.

• Legal considerations

  Sound weapons, especially those used for self-defense, are subject to legal considerations. Therefore, it is important to research local laws and regulations governing the ownership, use, and deployment of sound weapons. This ensures compliance and avoids potential legal issues.

• Portability and ease of use

  Portability is an important factor, especially for personal sound weapons. It is important to consider the weight, size, and design of the sound weapon. These factors determine if it can be carried around easily. Additionally, the ease of use should also be considered. This includes the controls and settings of the device. Choosing a sound weapon with simple controls ensures that one can operate it effectively during high-stress situations.

• Power source and duration

  Different sound weapons use different power sources. They can be battery-powered, rechargeable, or AC-powered. Each power source has its advantages and disadvantages. For instance, battery-powered devices offer portability but limited usage time. On the other hand, sound weapons with AC power sources are not portable but can be used for long periods. It is also important to consider the battery life and charging options of the sound weapon. This ensures that it is always ready for use.

Function, feature, and design of sound weapon

Function

A sound weapon, also known as an acoustic weapon or sonic weapon, is designed to use sound waves, typically at high volumes or specific frequencies, for various purposes, including military, law enforcement, crowd control, and personal defense. The primary function of a sound weapon is to incapacitate, deter, or displace individuals or groups without causing permanent physical harm. These weapons exploit the physiological and psychological effects of sound on humans, aiming to cause discomfort, pain, or disorientation at controlled levels.

Feature

• Non-lethal deterrence: Sound weapons are developed to be non-lethal, meaning they aim to incapacitate or deter individuals without causing permanent harm or death. This makes them appealing for law enforcement and military applications where deadly force is not justified or necessary.
