Road traffic noise detecting system and method based on electrocardiographic index

Abstract

The invention discloses a road traffic noise detecting system and method based on an electrocardiographic index. The road traffic noise detecting method comprises the following steps of: establishing a road traffic noise evaluation characteristic information detecting system; establishing the road traffic noise detecting system based on the electrocardiographic index and a method model; and using the road traffic noise evaluation characteristic information detecting system and a calculation model, so as to determine an urban road traffic noise sound pressure level through data analysis. Compared with the conventional subjective qualitative evaluation method, the road traffic noise detecting method based on the electrocardiographic index disclosed by the invention can more objectively and qualitatively describe the influence of road traffic noise on human bodies because the method is built on the basis of tests of the influences of traffic noise on psychology and physiology of human bodies, so that the influence degree of the noise on the human health can be actually reflected.

Description

technical field [0001] The invention belongs to the technical field of road traffic noise detection, and in particular relates to a road traffic noise detection system and method based on electrocardiogram indicators. Background technique [0002] At present, urban environmental noise pollution has become an important environmental protection problem faced by large cities all over the world. With the rapid advancement of urban industrialization, traffic noise has gradually become the main component of urban noise. Noise pollution has seriously affected people's normal work, study and rest. The number of noise pollution complaints has always ranked first in various environmental pollution lawsuits, directly affecting social stability and normal social order. [0003] When the human body is disturbed by noise, it will produce psychological and physiological discomfort. These discomforts can be divided into two types: those that can be recovered in a short time and those that ...
