Decibels are a unit of measurement that is what mathematicians call logarithmic, meaning it goes up in powers of ten. That means a decibel number that’s 10 percent higher than another isn’t going to be 10 percent louder. No, a 70 dB sound is actually twice as loud as a 60 dB sound. And a 50 dB sound is one-fourth quieter than …Decibel is a logarithmic unit to express the ratio of sound intensity (volume) and is important as an indicator of the background noise level. Humans can hear sounds between 0 and 140 decibels. The value of decibels has no direct or indirect correlation with the sound frequency.The key is the two simple rules of thumb shown below. These rules allow you to move back and forth between intensity and sound intensity level without a calculator: Change in intensity. Change in intensity level. Multiply/divide by two. Add/subtract 3 dB. Multiply/divide by ten. Add/subtract 10 dB.The VLIKE LCD Digital Audio Decibel Meter provides plenty of options for ensuring total safety for you, friends, staff, and customers in a wide range of scenarios.
