The decibel scale is a reflection of the logarithmic response of the human ear to changes in sound intensity:. The logarithm to the base 10 used in this expression is just the power of 10 of the quantity in brackets according to the basic definition of the logarithm: The decibel scale starts 0, the softest sound a human can detect, and increases in multiples of 10 dB. Every increase of 3 dB represents a doubling of sound intensity or acoustic power. Table 1 lists the common sounds that are heard: Table 1: Common Sounds Decibel Scale.

At 112 decibels, damage can occur with only one minute of exposure. At 140 decibels, immediate nerve damage can occur. Firearms, firecrackers, and jet engines taking off are all louder than 140 dB.

This measurement is known as maximum sound pressure level ( SPL ). For example, Audio-Technica’s BP4029 stereo shotgun condenser microphone can handle a maximum of 126 dB (click the “Specifications” tab at the link above). The human range for decibel intensity detection starts from 0 and goes up to about 150 decibels. Generally speaking, anything that goes above 80 decibels has the potential to harm our hearing range. Hence, it’s fair to say that if you’re approaching 80+ decibels, it is too loud.
