"NOISE THERMOMETER": A LARGE DISPLAY SOUND-LEVEL METER

A LARGE-DISPLAY SOUND-LEVEL METER HAS BEEN CONSTRUCTED AS AN EXPERIMENT IN PUBLIC EDUCATION. THE INDICATOR IS AN ARRAY OF LIGHTS SO ARRANGED THAT THE SOUND LEVEL PRODUCED BY A SOURCE IS DISPLAYED AS AN ILLUMINATED COLUMN. IN A ROADSIDE INSTALLATION, MOTORISTS SEE A THERMOMETER-LIKE DISPLAY AHEAD AND CAN COMPARE THE LEVEL PRODUCED BY THEIR OWN VEHICLES WITH THE MAXIMUM LEVEL PERMITTED BY LEGISLATION, AS SHOWN BY VEHICLE SILHOUETTES. THE DEVICE REGISTERS FROM 70-100 DBA IN 2-DBA STEPS WITH AN ACCURACY APPROXIMATELY EQUAL TO ONE INCREMENT OF THE SCALE. IN EDMONTON, ALBERTA, THE NOISE THERMOMETER SERVED AS AN EXCELLENT FOCUS FOR PUBLICIZING THE INTRODUCTION OF MUNICIPAL ANTINOISE LEGISLATION AND WAS LOCATED ON MANY STREETS OVER A FIVE-MONTH PERIOD. /AUTHOR/
