Abstract

The invention discloses a high-accuracy individual noise measurement method which is characterized in that an individual noise measurement device can be fixed on a safety cap and is provided with two microphones as high as ears, and the microphones are arranged on the left side and the right side. Compared with the prior art, the high-accuracy individual noise measurement method has the advantages that the measurement result can respectively display and record noise strength of the left ear, noise strength of the right ear and mean noise strength of the left ear and the right ear, and equivalent continuous A-weighted sound pressure levels can be computed respectively and simultaneously; the individual noise measurement device can be carried by a person under detection conveniently, and the microphones are always as high as the ears when workers work; accuracy of individual noise measurement results is ensured.

Description

The individual noise measuring method of a kind of high accuracy
Technical field
The present invention relates to individual noise measuring method in occupational health and field of environment protection.
Background technology
At present, there are following two kinds of drawbacks in individual noise measuring method domestic, external use: (1) microphone can only be measured the noise intensity of monaural contact, causes the one-sidedness of measurement result.(2) laborer's activity causes microphone position can not keep same high with laborer ear always, affects the accuracy of measurement result.Domestic, abroad use and the individual noise-measuring system sold new by looking into, there is no both at home and abroad at present and a kind ofly can measure left and right ear noise intensity and microphone position keeps with laborer ear with high individual noise measuring method simultaneously always.
Summary of the invention
The present invention, in order to solve the above-mentioned deficiency of prior art, provides a kind of high accuracy individual noise measuring method.
Above-mentioned purpose of the present invention realizes by following technical scheme: it is characterized in that: individual noise-measuring system can be fixed on safety helmet, and this device has two microphones, microphone and ear's co-altitude, and a microphone is each side installed.
The present invention's advantage is compared with prior art: measurement result can show respectively and record left ear, auris dextra, left and right ear average noise intensity and calculate respectively equivalent continuous A sound level simultaneously; Be convenient to detected person and carry, when microphone is worked with laborer all the time, the height of ear is consistent; Ensure the accuracy of individual noise measurement result.
Brief description of the drawings
Fig. 1 is hardware block diagram of the present invention;
Fig. 2 is scheme of installation of the present invention.
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in Figure 1, microphone 1,2 receives external voice signal, amplifier 3 carries out power amplification to sound pressure signal respectively and obtains sound signal, respectively sound signal is converted to corresponding pulse signal through converter 4, single-chip microcomputer 5 respectively pulse signals carries out computing, controls finally by display 7 display measurement results by operation keyboard 6.
As shown in Figure 2, microphone 1,2 is arranged on safety helmet 5 both sides, and main frame 4 is arranged on safety helmet 5 rear portions, and microphone 1,2 is connected by signal wire 3 with main frame 4.
This measuring method (1) equipment is convenient to install and detected person carries.(2) when during measurement, microphone is worked with laborer all the time, the height of ear is consistent.(3) measurement result can show respectively left ear, auris dextra, left and right ear average noise intensity.(4) ensure the accuracy of individual noise measurement result.
Above-mentioned embodiment is exemplary, is to be the restriction that this patent is comprised to scope in order better to make those skilled in the art can understand this patent, can not to be interpreted as; As long as any being equal to done according to spirit that this patent discloses changes or modify, all fall into the scope that this patent comprises.

Claims (1)

1. the individual noise measuring method of high accuracy, is characterized in that: individual noise-measuring system can be fixed on safety helmet, and this device has two microphones, microphone and ear's co-altitude, and a microphone is each side installed.
