• Noise is an intense factor in affecting human health.Harmful environmental noise is defined as daytime, evening and night-time noise levels exceeding 65 – 60 – 55 decibels, depending on the source of noiseOver half of Barcelona’s population is subjected to noise levels over 65 decibels during the entire day (0800-2200 hours) which explains why locals have to shout to make themselves heard.
