Nan jeni nan aplikasyon souvan wè definisyon an nan w pèdi diferan fason (jis gade diferan). Pou pouvwa a, dB = 10 * lg (A / B). Pou vòltaj oswa kounye a, dB = 20 * lg (A / B). Isit la A, B Konparezon ki gen pouvwa a reprezante nan valè oswa valè aktyèl ak vòltaj.

In the engineering applications often see the definition of seemingly different ways (just look different). For power, dB = 10 * lg (A / B). For voltage or current, dB = 20 * lg (A / B). Here A, B Comparison of the power represented in values or current and voltage values.
