Labeled as “the world’s loudest whistle,” it is 8 times louder than the normal whistle referees use during ballgames. Hyperwhistle is certified to generate around 142 decibels of sound. That is about as loud as hearing an aircraft engine powering up from a distance, doing for a loud noise that’s possibly downright annoying. Given that it’s deafening, it features earplugs you can use when you plan to use the whistle and need to make sure it doesn’t do a whole lot of damage to your ear.
The volume is determined by the volume of air you exhale into the tube. If you wish the sound to be a bit gentler on the ears, simply just don’t blow as hard into the tube. Obviously, you’ll need to do some testing to discover the best amount of air to get the specific kind of sound you will need, but that’s something a lot of people find out soon after use.
The Hyperwhistle is apparently so loud; you will hear its sound from over a couple of miles, which makes it an outstanding survival device for when you’re looking for your buddies during an exploration. The extremely loud sound rolls courtesy of the whistle’s distinctive “radial tri-frequency” model.
The design is an anti-microbial composite component that’s made for all-weather usage, with a thick-walled design that should shrug off flaws and scratches like they’re nothing. And, sure, they can be used in aquatic environments, since there are no moving components that are usually damaged by water, regardless if scuba diving at deeper ranges. It’s also obviously buoyant, so the damn thing will float in case you drop or lose it while fishing, kayaking or scuba diving.
