ZJLWYZQQ 300DB Super Loud Train Horns, 12V Waterproof Air Horns Replacement Kit, Car, Motorcycle, Truck, Bike, Boat Car Air Electric Snail Double Horn, Automotive Accessories Universal for Car

Surprisingly it's sound like a old honda horn. It's not loud at all

Very easy to install on my Harley. Now the Squirrel do not laugh at me anymore with the stupid default motorcycle horn. Also cars can hear me much better with the lower and louder horn.

No louder than the OEM horn.

Same loudness as my original horn.

Not super loud at all it sound the same as my stock horn, kinda disappointed!!!!

Easy installation. Way louder than the toy OEM.

Worked exactly as advertised. I can’t imagine anything more incredible.A sound level of 300 decibels (dB) is far beyond anything naturally occurring or survivable. To put it in perspective, decibels measure sound intensity logarithmically, and each 10 dB increase represents a tenfold increase in intensity. For comparison, a jet engine at close range is about 150 dB, and the threshold for immediate physical damage to human ears is around 180-190 dB.At 300 dB, the energy involved is astronomical—comparable to the output of a massive explosion or theoretical events like a meteor impact. The effects on a person would be catastrophic and instantaneous:• Immediate physical destruction: The pressure wave would cause total disintegration of the body, including tissues, organs, and bones, due to the extreme energy transfer. This is far beyond mere hearing damage; it’s akin to being obliterated by a shockwave.• Environmental impact: The sound would create a blast wave powerful enough to demolish structures, vaporize materials, and potentially cause seismic effects. No human could survive the secondary effects of such an event, like heat or debris.In reality, 300 dB is practically impossible in Earth’s atmosphere, as air molecules can only transmit so much energy before breaking down into plasma or other states. The loudest recorded sound, like the 1883 Krakatoa eruption, was estimated at around 180-190 dB at its source, and even that caused widespread injury and death.In short, 300 dB would not just kill a person—it would annihilate them and everything nearby. The scenario is more science fiction than practical reality.

Not very loud at all. Disappointed.
