(often cited as the 2022 international version) is the primary standard for measuring room acoustic parameters in unoccupied open-plan offices . Unlike Part 2, which focuses on temporal decay (reverberation), Part 3 focuses on spatial decay , or how sound levels drop as you move away from a speaker.
