Dawn signals propagate twenty times more effectively than midday ones

Evidence

After the application of this model these two authors have found that the early morning is the most favorable period for sound propagation when compared with other times of day and night. The biophonies produced at that time are 20 fold more effective than the same signal with the same amplitude produced at midday. — Almo Farina, Soundscape Ecology, 1682
