Weaponized use of LRADs or other acoustic hailing devices against U.S. citizens should be banned and deemed a violation of 14th Amendment rights, prosecutable by law.

Can you block LRAD?

LRADs are designed to produce VERY loud sound, and loud sound can cause significant damage to our auditory (hearing) and vestibular (balance) systems. It is not possible to fully protect yourself​ from potential hearing damage from an LRAD! (The only way to protect civilians from LRADs is to ​not use​ LRADs.)

How do LRADs work?

An LRAD is a loudspeaker-like device that emits a focused beam of sound. What makes these systems unique is that rather than transmitting sound like a loudspeaker in many directions (similar to the way a lightbulb emits light), LRAD systems transmit sound in a narrow beam (much like a flashlight).

Do noise Cancelling headphones work against LRAD?

○ (Noise-cancelling headphones are NOT the same as protective earmuffs. Noise-cancelling headphones are good at cancelling low-frequency sound, but the deterrent tone of an LRAD is high frequency.)

Is LRAD real?

What does an LRAD feel like?

Short-term exposure to loud noise like the LRAD’s deterrent tone may cause a sensation of stuffed or ringing ears, known as tinnitus, which can cease minutes after the exposure or last for days. Other sound injury symptoms include headaches, nausea, sweating, vertigo, and loss of balance.

Are LRADs being used?
