SOUND EMISSION AS AN ENVIRONMENTAL FACTOR

LAERMIMMISSIONEN ALS UMWELTFAKTOR

FOLLOWING A SHORT DESCRIPTION OF SOUND MEASUREMENT, THE HEARING PROCESS AND NOISE EFFECTS ARE DISCUSSED. THE FOLLOWING FACTORS ARE DECISIVE FOR THE MEASUREMENT OF SUBJECTIVE RECEPTIVITY OF DISTURBANCE AND NOISE LOADING: THE SOUND LEVEL, THE CHARACTER OF THE NOISE, THE FREQUENCY COMPOSITION, THE OCCUPATION AND INTENTIONS OF THOSE EXPOSED, THE PSYCHOLOGICAL APPROACH TO THE NOISE SOURCE AND THE NATURE OF THE EXPERIENCE WHICH A PERSON HAS PREVIOUSLY HAD WITH A PARTICULAR NOISE. THE NOISE EXPOSURE FROM TRAFFIC NOISE IS DEPENDENT ON THE TRAFFIC DENSITY, THE DISTANCE BETWEEN THE HIGHWAY AND THE EXPOSED PERSON AS WELL AS NOISE BARRIERS. TWO STUDIES HAVE PROVIDED INFORMATION ON THE EFFECTS OF TRAFFIC NOISE ON INHABITANTS: AROUND 25% OF 800 NEWLY CONSTRUCTED DWELLINGS IN ZURICH EXPERIENCE NOISE LEVELS WHICH CAN BE DESCRIBED AS VERY HIGH. A RELATION IS DEMONSTRATED BETWEEN THE MEASURED NOISE (NOISE LOADING OR NOISE EXPOSURE) AND THE NOISE EXPERIENCED (DISTURBANCE). 27% OF PEOPLE QUESTIONED FELT STRONGLY DISTURBED BY A NOISE LEVEL OF 61 TO 65 DB(A), 60% BY A LEVEL OF 66 TO 70 DB(A). WHERE PEOPLE WERE QUESTIONED REGARDING THEIR REASONS FOR CHANGING ADDRESS, NOISE CLEARLY DOMINATED IN COMPARISON TO OTHER MOTIVES WHERE THE NOISE LEVEL EXCEEDED 65 DB(A). THE SECOND STUDY CARRIED OUT IN BASLE WAS CONCERNED AMONGST OTHER THINGS WITH THE EFFECT OF TRAFFIC NOISE IN THE NIGHT. WITH AN INCREASING NOISE LEVEL, THE PERCENTAGE OF PEOPLE EXPERIENCING DISTURBED SLEEP INCREASED.
