Web5 de nov. de 2024 · Sound Intensity. Sound intensity can be found from the following equation: I = Δ p 2 2 ρ v w. Δp – change in pressure, or amplitudeρ – density of the material the sound is traveling throughv w – speed of observed sound.Now we have a way to calculate the sound intensity, so lets talk about observed intensity. Webmore. The decibel measures sound pressure or electrical pressure (voltage) levels. It is a logarithmic unit that describes a ratio of two intensities, such as two different sound pressures, two different voltages, and so on. A bel (named after Alexander Graham Bell) is a base-ten logarithm of the ratio between two signals.
