How far can a human yell be heard?
Under ideal conditions, the range of the male human voice is about 180 metres while still being intelligible. Sound pressure level normally halves (by six decibels) for each doubling of distance, so you might still be able to hear the speaker’s voice at 360 metres even if you can’t understand what they are saying.

CAN 1100 dB create a black hole?
With energy as great as 1100 dB, it would create enough gravity to cause a black hole to form, and an incredibly large one at that. Decibels are a logarithmic unit. That means 20 decibels isn’t 2 times more powerful than 10 decibels, it’s 10 times more powerful.
What is the average decibel level of human speech?
Although it may be surprising, the average decibel level of human speech isn’t much louder. The sound level of normal conversation is between 50 and 65 decibels, speaking generally.

How many decibels is harmful to your hearing?
Sounds above 90 dB can lead to chronic hearing damage if people are exposed to them every day or all the time. Hearing becomes uncomfortable if the sound pressure level is above 110 decibels (threshold of discomfort), and it becomes painful above 130 decibels (threshold of pain).
