Certain LRADs are capable of creating sounds nearly twice as loud, The technology company Genasys Inc., which manufactures LRADs, admitted in a The devices have been reportedly used on protesters in the United States in the past month.

The Wispon (ウィスポン, Wisupon?) If you do not do so, you run the risk of experiencing short-term migraines, dizziness and hearing loss, as well as a long-term side effect of becoming excessively sensitive to lesser noises. Some sonic weapons are currently in limited use or in research and development by military and police forces.

Tests performed on mice show the threshold for both lung and liver damage occurs at about 184 dB. This limited frequency range—200 Hz to 10 kHz, roughly the same as human speech—combines with the efficient drivers and horn loading to produce the destructive tone. A local professor suffered permanent hearing damage, and won a settlement against the Likewise, there is an ongoing lawsuit in New York City in which the plaintiffs claim that a LRAD used while they protested the LRADs were originally developed by the military after the bombing of the ATC started working on military applications for the technology, which they then dubbed "High Intensity Directed Acoustics." “In contrast, some LRADs can create sounds up to about 160 dB when used at their full power.”Robert Auld, an audio engineer and former chair of the New York chapter of the Audio Engineers Society, is one of many in his trade who sees LRAD deployment as a military-style escalation of force.
The apparent sonic attacks on the US embassy in Cuba rekindled decades-old fears about a different kind of secret weapon. No follow up experiments were recommended. At the time, ATC Since then, they have become so ubiquitous in their use for crowd control that scholars are trying to find ways to offset their impact. Subliminal MessagingIt’s been well established that subliminal messaging is used extensively in … “There is nothing particularly sophisticated about it.”As reports of LRADs used on civilians roll in, sound specialists and “Remember that the LRAD beams sound in a narrow pattern, so move off to one side to get out of the main pattern,” Auld says.Carr suggested treating LRADs as a warning from police that they’re about to escalate violence, even if it starts out as a public service announcement.
