Wouldn't the enemy get used to it? Can't they also just wear earmuffs?
I doubt that earmuffs are going to help much against sounds as loud as that. According to this website:The threshold of pain is 130 dB, anything above that level causes immediate ear damage.
To be honest, I think this will have two usages: riot control and laying the groundwork for an actual laser weapon.
To be more accurate, it's a tool for the police state. Next time the peasants demand that they be looted and subjugated less, the new laser guns will come in handy! Oh but of course. Only $3 million. That's a small price for us to pay for weapons that will be used to subjugate us. In reality, it will be way more expensive of course. Cronies being cronies and all.The total cost will be about $3 million, paid out in two $1.5-million small-business-innovation-research contracts to Physical Optics Corp., which is working on the lighting effects, and a Tucson-based company called GEOST, which is working on the sound.
