Total intensity in decibel formula

WebOct 28, 2024 · The decibel unit (symbol dB) is a logarithmic unit expressing the ratio between two values. The decibel was named in honor of the famous scientist Alexander Graham Bell (1847-1922). When measuring sound, we use the following logarithmic formula to determine the sound pressure level (SPL) in decibels. WebSound Intensity is the power per unit area carried by a wave. Power is the rate that energy is transferred by a wave. The equation used to calculate this intensity, I, is: I = P/A. P is the power going through the area, A. The SI unit for intensity is watts per meter squared or W/m2. This is the general intensity formula, but let’s look at it ...
