Äänitasojen
Äänitasojen is a Finnish term related to sound levels; it is the genitive plural form of äänitaso and is used in contexts discussing different measures or aspects of acoustic level. The concept refers to quantitative assessments of sound intensity or pressure, commonly expressed in decibels (dB) on a logarithmic scale relative to a reference pressure (20 μPa in air).
Measurement of äänitasot includes instantaneous, peak and time‑averaged metrics such as Leq (equivalent continuous sound level).
Applications span audio engineering (mixing, headroom, dynamic range), occupational health (limits and exposure durations to prevent
