Decibels
20 to 50 decibels (dB).
To calculate the number of decibels that power-level-'A' is greater than power-level-'B',-- Divide 'A' by 'B'-- Take the 'log' of the quotient-- Multiply the 'log' by 10 .If the result is negative, then 'A' is that many decibels lower than 'B'.
The decibel level for standard human voices is around 60 decibels, which is also the level for singing birds. Hearing loss occurs at around 110 decibels with painful hearing loss occurring at 130 decibels.

Aome machines claim to spin at 74 decibels. Is that loud?
Fundamentally, 43 decibels is loud. It is probably enough to annoy neighbors, but anything 85 decibels is enough to hurt hearing.
About as loud as a normal conversation.
listening to loud audio for a long period time can decibels your ears.
yes it is... its almost high enough to make you deaf.........LOL! 8.9 decibels is very, very quiet. It is quieter than a whisper. 70 decibels is loud. 140 decibels is painfully loud.
Cockatoo-134 decibels
104 decibels
It would be about 80 decibels if you were nearby.
57 decibels is about the noise that a high speed toothbrush makes or the low setting on an alarm clock or telephone. It can be loud enough to wake you up.
Sound is measured in decibels. Decibels are units used to measure the intensity of sound. The highest decibel alarm clock available is 120 decibels, which can be compared to be as loud as the sound of a fire engine siren.
Decibels are really more a measure of sound level. 65 decibels would be about the level of normal conversation or laughter.
A sound at 15 decibels is not very load. It is equivalent to the sound that watch makes when ticking.
