Why is 194 dB the loudest sound possible?
But there’s a limit to how loud a sound can get.
At some point, the fluctuations in air pressure are so large that the low pressure regions hit zero pressure — a vacuum — and you can’t get any lower than that.
This limit happens to be about 194 decibels for a sound in Earth’s atmosphere..

What frequency can kill you?
The most dangerous frequency is at the median alpha-rhythm frequencies of the brain: 7 hz. This is also the resonant frequency of the body’s organs.
Can a sperm whale kill you with sound?
Sperm whales are the loudest mammals on the planet, with vocalizations reaching an astonishing 230 decibels. … At around 150 decibels your eardrums will burst, and the threshold for death is estimated to be in the range of 180 to 200.
How loud should you listen to music?
Experts recommend keeping sound levels at somewhere between 60 and 85 decibels to minimize the damage your ears are exposed to. If you are listening to music at around 100 decibels, restrict your usage to within 15 mins.
How loud is a silenced gun?
According to a fact sheet from SilencerCo, a Utah-based silencer manufacturer, a 12-gauge shotgun equipped with a silencer registers 137 decibels and a silenced . 22 rifle is muffled to 116 decibels, slightly louder than an ambulance siren. Still loud, just not eardrum-busting loud.
What is the loudest sound in the universe?
Soundwaves require a medium to propagate, so we can’t really “hear” interstellar objects. The loudest sound recorded on Earth was “The Bloop”.
Can sound kill you?
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.
What is the loudest fart?

What does 0 decibels sound like?
So 0 dB does not mean no sound, it means a sound level where the sound pressure is equal to that of the reference level. This is a small pressure, but not zero. It is also possible to have negative sound levels: – 20 dB would mean a sound with pressure 10 times smaller than the reference pressure, i.e. 2 μPa.
Can sound kill bacteria?
Newsletter. High-frequency sound can kill microscopic pathogens, but the sound waves normally need to travel through a contact medium such as water or gel, limiting the use of ultrasound as a germicide.
