These sound waves can travel for hundreds of miles under water, and can retain an intensity of 140 decibels as far as 300 miles from their source..

Why is 194 dB the loudest sound possible?

A note on the loudest possible sound in air A sound of 194 dB has a pressure deviation of 101.325 kPa, which is ambient pressure at sea level, at 0 degrees Celsius (32 Fahrenheit). Essentially, at 194 dB, the waves are creating a complete vacuum between themselves.

Is 70 dB loud?

Sound is measured in decibels (dB). A whisper is about 30 dB, normal conversation is about 60 dB, and a motorcycle engine running is about 95 dB. Noise above 70 dB over a prolonged period of time may start to damage your hearing. Loud noise above 120 dB can cause immediate harm to your ears.

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.

How long can you listen to 100 dB?

Scientists recommend no more than 15 minutes of unprotected exposure to sounds that are 100 decibels. In addition, regular exposure to sounds at 110 decibels for more than one minute risks permanent hearing loss.

How loud is 1000db?

On the decibel scale, the smallest audible sound is 0 dB. A sound that is 10 times more powerful would be measured at 10 dB. A sound that is 100 times more powerful than total silence would be 20 dB. A sound that is 1,000 louder than silence would be measured at 30 dB.

What is acceptable noise level?

For peak noise, the national standard is a peak sound pressure level of 140 decibels. … The levels specified in the national standard are the maximum acceptable exposure levels for noise in the workplace. However, over long periods, repeated exposure to noise between 75 and 85 decibels may be a small risk to some people.

How noisy is 58 decibels?
