Perceived sound predominance is measured by percentage of time heard times rated volume

Evidence

In this research a questionnaire was created according to a list of seven types of perceived sounds: background city, happy people sound, sounds from surrounding buildings, natural sounds, object sound from people in the park, individual vehicles, or aircraft sounds, and sad and angry people. For every sound type was requested the percentage (0 %, 50 %, 100 %) of the time each sound was heard. Also for each sound type was requested the “average volume” they heard according a scale ranging from quiet (1) to loud (7). Sound predominance was obtained by multiplying the two scores. — Almo Farina, Soundscape Ecology, 1061
