Values greater than that reference point are written as positive numbers, while values lesser than that reference point are written as negative numbers. It is a logarithmic unit that describes a ratio of two intensities, such as two different sound pressures, two different voltages, and so on. The decibel tells us that the level difference caused by changing a value will depend on the initial value and the percentage that it has changed. You can use those three as the same if you are not at the upper limit with your loads. There is no link between frequency and intensity. Decibels are the unit of measurement for sound, abbreviated dB. This is irrelevant but just curious; if it's a decibel shouldn't that be a tenth of a bel and you'd instead be multiplying by 1/10, not multiply by 10?
