Infrasound monitoring technologies

On the contrary, the infrasonic region of the spectrum is still under investigation. The first studies on the presence of air-borne infrasound go back to the end of the 19th century and its effects on the human beings have been investigated since the World War II. This paper reports an overview of the technologies used to detect infrasound in different research fields, pointing out their pros and cons. System specification for urban area infrasound noise monitoring requires transportability, robustness, reduced dimensions to avoid large space occupation and low cost devices for a distributed monitoring.
