Pigeon Patrol UltrasonicPigeon Patrol Products and Services wonder if Ultrasonic sound can kill you? The short answer is “yes”.

The Space Shuttle’s Mobile Launch Platform used to dump 300,000 gallons of water onto the platform during launch, to absorb the intense acoustic energy that would otherwise damage the Shuttle. Giant air horns, using nitrogen gas to produce sounds as loud as 154 decibels.

The question is, is 154 decibels enough to kill you? In all honesty, probably not — unless, perhaps, you were stuck with your head inside the horn for a prolonged period. 150 decibels is usually considered enough to burst your eardrums, but the threshold for death is usually pegged at around 185-200 dB. A passenger car driving by at 25 feet is about 60 dB, being next to a jackhammer or lawn mower is around 100 dB, a nearby chainsaw is 120 dB. Generally, 150 dB (eardrum rupture) is only achieved if you stand really close to a jet aircraft during take-off or you’re near an explosive blast.

The general consensus is that a loud enough sound could cause an air embolism in your lungs, which then travels to your heart and kills you. Alternatively, your lungs might simply burst from the increased air pressure.

High-intensity ultrasonic sound (generally anything above 20KHz) can cause physical damage. Some very low frequencies (infrasound) can apparently cause your eyeballs to vibrate, making it very hard to see.
