How loud is 0 decibels?
0 decibels, being the threshold of human hearing in a laboratory setting, is quite quiet. This might be comparable to the dropping of a pin in on carpet. In most any case a normal human being would not even detect the noise source. Bear in mind sounds can measure in the negative decibels as well, 0 is not the threshold for sound altogether but simply the threshold for which human hearing begins detecting noises.
What is the decibel of a sound?
The decibel is the unit of measurement, one tenth of a Bel (B), used to measure sound intensity. The decibel is logarithmic in scale and thus represents a ratio. Sound is quite complex and consists of vibrations traveling through a medium, such as air.
What is the peak noise level of a drum set?
A drum set creates a peak noise level of 125 decibels at the moment of striking.
What is the maximum sound level?
Under normal atmospheric conditions the maximum sustained sound level achievable on earth is 194 decibels. The reason for this is that the oscillation of the sound wave can not drop below a vacuum created by the sound pressure in air. However, peak sound levels can achieve levels substantially higher than 194 decibels. One incredible example of this would be the volcanic eruption in Tambora, Indonesia in 1815 which ejected 36 cubic miles, equivalent to a 14 gigaton nuclear bomb based on ejected volume. The internal pressure is believed to have been 47 million pounds per square inch resulting in a measured peak decibel level of 347 dB. Click here for a chart of typical noise values.

Below that level, they are still able to cause permanent problems, including hearing loss and persistent tinnitus. Make sure you always have hearing protection, no matter how badass your car’s rig might be.
What is the lowest decibel?
Since it’s logarithmic and relative, the decibel scale is also limitless in both directions and doesn’t stop at 0. Zero dB is theoretically the lowest limit of human perception, but in practice, a human will rarely be able to hear a sound below 10 dB.
What is a decibel?
The decibel is the standard international unit used to measure volume. One decibel (1 dB) isn’t equal to anything that’s easy to describe in the real world — it comes from a complex equation involving pressure that we don’t need to get into right now.
What is the best decibel level to kill someone?
Since we’ve already established that being near sounds above 200 decibels will kill you instantly, these are just here as fun facts. Note that since it’s not possible to put a decibel meter near many of these events and have it survive, dB levels above 200 are mostly theoretical.

There is no safe amount of exposure to volumes in this range. Being near a sound above 115 dB for any length of time without protection can cause permanent hearing damage. At this level, you’ll also begin to feel the sounds in parts of your body other than your ears.
Is 40 decibels a logarithmic or relative?
Instead, just remember that decibels are relative and logarithmic. Relative means that dB is only a useful measurement when compared to other dB values. Logarithmic means that, for every 10 dB, the corresponding real-world volume doubles. 40 dB is twice as loud as 30 dB, and half as loud as 50 dB.
