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).
