äänenvoimakkuudet
Äänenvoimakkuudet refers to the perceived loudness of a sound. It is a subjective experience influenced by several physical factors, most notably the sound pressure level, but also by the frequency of the sound and the duration of its exposure. In acoustics, sound pressure level is the objective measurement of the intensity of a sound wave. This is typically measured in decibels (dB), where a higher decibel value generally corresponds to a louder sound.
However, human hearing is not equally sensitive to all frequencies. We are most sensitive to frequencies in
Duration also plays a role. A sound that is present for a longer period may be perceived
