The word “decibel” comes from “deci” (meaning “one-tenth”). pki kostenmodell

"WebbThe A-weighted sound levels closely match the perception of loudness by the human ear. Decibels are measured on a logarithmic scale which means that a small change in the number of decibels results in a huge change in the amount of noise and the potential damage to a person's hearing.
