Technology / Home Audio / Frequency: 1. The property or condition of occurring at frequent intervals. 2. Mathematics. Physics. The number of times a specified phenomenon occurs within a specified interval. In sound this simply refgers to the regular occurence of compression and rarification of air that we experience as sound.
