ekvivalenttiäänitaso
Ekvivalenttiäänitaso refers to the equivalent sound pressure level of a noise that is perceived to be as loud as a specific, often complex, noise event. This concept is used in acoustics and noise assessment to simplify the measurement and understanding of fluctuating or intermittent noise sources. Instead of describing a sound event by its varying intensity over time, a single equivalent level is used to represent its overall impact.
The calculation of ekvivalenttiäänitaso typically involves averaging the sound pressure level over a defined period. This
This equivalent level is particularly useful for assessing environmental noise, such as traffic noise, industrial noise,
