How to measure decibels.

Measuring the speaker would be a possibility but the earphones, no, different earphones have different inherent values (impedance, resistance, material etc) that makes it impossible for the phone to know how loud the sound may be. How you wear them also makes a difference. In fact the area of the highest decibels is very limited.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 decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel ( B ). It expresses the ratio of two values of a power or root-power quantity on a logarithmic scale. Two signals whose levels differ by one decibel have a power ratio of 10 1/10 (approximately 1.26) or root-power ratio of 10 1/20 (approximately 1.12 ).Oct 5, 2021 · To help measure the different levels of sound and deem which ones are safe and harmful, experts use a nonlinear scale to describe the intensity of sound waves conveniently.
