big whistle zing out

A siren whistle sound effect created by Hanna-Barbera that is used in almost every freaking animated show. It was used regularly in their productions before the studio made their library royalty-free. That's when the sound spread to other studios. Nowadays, people are getting tired of hearing the sound especially when it's used in the more recent animated shows and films, and even some video games made use of it! This sound is considered a mentally ill person's worst nightmare (or perhaps the entire Hanna-Barbera sound library). For some, they're just uncomfortable to hear, and for some, they pose a real health concern. Made especially worse if you have autism or Asperger's. If you hear just one sound or even this, you will have a heart attack or ligma, or a mental breakdown that could land you with PTSD. Better watch yourself when you watch YouTube because both can kill. But also beware of the sound being played in public. If possible, wear headphones with music turned up to max volume.
