Sonic disperser is a kind of sound directional transmission equipment, can realize long-distance shouting, warning, deterrent function.
When people without any protection in the presence of 120 decibels above the volume of audible sound environment will feel uncomfortable or damage the hearing system, when the volume rises to 150 decibels above the people in this environment will be in the tympanic membrane rupture hemorrhage, loss of hearing, and even insanity.
In the premise of non-contact, non-lethal, dispersal of the assembly crowd of intelligent defense equipment. The equipment can actively release strong noise, making it difficult for people to stay in front of it without protective measures to protect them. When facing events such as illegal crowd gatherings or riots, the product will provide law enforcement officers with an invisible high-energy acoustic wall of protection while controlling and dispersing illegal crowds more effectively.
Expanded Information
The Directed Acoustic Weapon is a long-range acoustic device that can emit high-energy sound waves up to 150 decibels, which is even louder than the noise emitted by jet airplane engines. This annoying noise clearly conveys the intent that approach is forbidden.
This reduces "misunderstandings". If the target insists on approaching, the high-decibel sound waves may cause permanent damage to their hearing for the purpose of attacking the enemy.
The device looks like an ordinary loudspeaker, but it is actually a high-tech police equipment. In actual use, the operator can first shout to ask the target object to cooperate with the action, if the other party does not respond appropriately, then the device can be aimed at 15 to 30 degrees within the angle of the target, focusing on 145 decibels of warning sound, in order to force the object to cooperate.
In recent years, China has insisted on taking the road of civil-military integration and development, and the application of acoustic devices in the country has developed rapidly ahead of its time and has reached an international leading level.
Guangzhou Sound Electronic Technology Co., Ltd. is a company focusing on "sound defense" in the field of audio product development and production of the company, has developed a series of high acoustic pressure, long-range, low-power, high voice clarity of the special acoustic products, both the military's special military audio systems, commercial sound reinforcement systems, but also for emergency rescue emergency product solutions. Emergency product program for emergency rescue.
