Abstract
The technological progress caused that the ambulance cars are
#audible-noise dampened. It’s very important that the emergency
signal is very loud. Many publications described this exposure
and #health consequences both to medical staff and #patients [1-
3]. The elements of cars like engine and suspension of vehicles
can generate also infrasonic noise near audible frequencies. This
problem was not described in detail in scientific literature. The
sources of infrasound in ambulance cars are very numerous: engine
and other #mobile elements, #suspension, tires and air movement.
The levels of exposure to #infrasound depend among others from:
vehicle speed, kind and quality of cars and roads and open or
closed windows. It’s possible in many cases that this exposure can
be higher in rural conditions (quality of roads and longer driving
times and distances).
