How loud can a human yell?
Human screams can be quite loud, possibly exceeding 100 dB (as of March 2019, the world record is 129 dB!) —but you probably want to avoid that because screams that loud can hurt your ears! You should also have found sound levels drop off quickly as you get farther from the source.
Can a sperm whale kill you with sound?
Sperm whales are the loudest mammals on the planet, with vocalizations reaching an astonishing 230 decibels. For reference, a jet engine from 100 feet away produces about 140 decibels.

You can listen to sounds at 70 dBA or lower for as long as you want. Sounds at 85 dBA can lead to hearing loss if you listen to them for more than 8 hours at a time. Sounds over 85 dBa can damage your hearing faster. The safe listening time is cut in half for every 3-dB rise in noise levels over 85 dBA.
What does 52 decibels sound like?
If an item is 52 dB(A), then it has a sound similar in intensity to a electric fan, hair dryer, a running refrigerator and a quiet street. Other common sounds include a blender at 90 dB(A), diesel truck 100 dB(A) and a crying baby can reach 110 dB(A).
Why is 194 dB the loudest sound possible?
The loudest a sustained sound can possibly be on Earth’s surface is 194 dB—which is when the amplitude of the sound wave is so intense that the low pressure part is a perfect vacuum (the wave alternates between double the normal atmospheric pressure and no air at all—not something you want to be present for).
Is 55 dB harmful?
Normal conversation is about 60 dB, a lawn mower is about 90 dB, and a loud rock concert is about 120 dB. In general, sounds above 85 are harmful, depending on how long and how often you are exposed to them and whether you wear hearing protection, such as earplugs or earmuffs.
