Description
Technical field
The utility model relates to a kind of Portable, personal noise level indicator.
Background technology
Show according to relevant data, 30% of urban environment noise pollution derives from road traffic noise, and 30% derives from commercial production and building operation, and 40% derives from social life.
In the development in city was built, road was constantly widened, and the track constantly increases, and the speed of a motor vehicle is constantly accelerated, and the city is constantly to external expansion, and the roadside skyscraper is on the increase, and the road traffic noise interference range is large, becomes the social concern that becomes increasingly conspicuous.
Along with the process of urban industry, produced increasing factory, just produced man-made noise thereupon.Construction noise pollution Monitoring Data in recent years shows, most of building operation circle noises all exceed standard.Building unit does not have corresponding Measures on Noise Control, and noise is discharged arbitrarily.The regulation of environmental protection department about forbidding carrying on construction work at night violated by some units in charge of construction, carries out continuously construction in 24 hours round the clock, resident on every side affected greatly, particularly the old,weak,sick and disabled crowd.
In recent years, China's economic development is rapid, and Urbanization Construction is advanced by leaps and bounds, and this is the day by day serious main cause of city noise pollution.
Noise pollution is disturbed and is had a rest and sleep.Having a rest and sleeping is that people eliminate fatigue, regain one's strength and keep healthy necessary condition.But noise is much troubled the people, is difficult to have a rest and sleep.The influence of noise pollution work efficiency.The research discovery, when noise was higher than 90 decibels, talk and thinking almost can not be carried out, and have a strong impact on people's working and learning, thereby can cause work efficiency to reduce.Noise pollution can act on the human central nervous system, and cardiovascular system etc. cause bad consequence.Noise also can produce certain infringement to eyesight.In addition, noise also all can produce harmful effect to women's endocrine dysfunction, if even fetus to accept noise in parent too many, also may occur neurobehavioral unusual after the birth.
The similar projects that is similar to individual noise monitor is also few, can erect the large instrument about the monitoring noise figure near some square.Also having some is noise monitors of building site special use.But these equipment all are hard-wired, can't constantly play the monitoring effect to the acoustic environment of people's daily life.
The utility model content
Technical problem to be solved in the utility model is to overcome deficiency of the prior art and Portable, personal noise level indicator that a kind of simple in structure, easy to carry, continuous monitoring is provided.
The technical scheme in the invention for solving the above technical problem is: this Portable, personal noise level indicator, comprise housing, be provided with display screen and switch on the housing, be provided with controller and battery in the housing, it is characterized in that: also be provided with model selection button and warning lamp on the housing, one side of housing is provided with audio signal reception device, described switch is connected with battery circuit, battery is connected with controller circuitry, and controller is connected with model selection button, display screen, audio signal reception device and warning light circuit respectively.
Battery described in the utility model is rechargeable battery.
Model selection button described in the utility model has three, is respectively sleep pattern button, daily life mode button and outdoor mode button, the datum that each model selection button is corresponding different.
Audio signal reception device described in the utility model is electret microphone.
Circuit described in the utility model connects and comprises neighbourhood noise collecting circuit, signal pre-processing circuit, peak-detector circuit and comparison output alarm circuit, the neighbourhood noise collecting circuit drives audio signal reception device and gathers environmental noise, and amplifies with impedance transformation with coupling next stage signal pre-processing circuit; Signal pre-processing circuit passes through capacitor filtering with the signal of neighbourhood noise collecting circuit output, filters out noise signal, then the following by inputting voltages device; Peak-detector circuit extracts voltage maximum in the sound signal as the employing voltage of sound signal; Relatively output alarm circuit compares the employing voltage of sound signal with the datum that sets, and output alarm signal when the employing voltage of sound signal is higher than datum drives warning lamp luminous.
The utility model compared with prior art has the following advantages: the function of (1) continuous monitoring: this noise monitor can carry out the detection of noise figure always after bringing into operation, constantly with three kinds of patterns under the noise figure set compare.The setting of (2) three kinds of scene modes: the sleep pattern noise figure is set as 35dB, and the daily life pattern is set as 60dB, and outdoor pattern is set as 85dB.Set according to the pattern that the user is different, this noise monitor will carry out with different standards the contrast of noise.When the ambient noise value is lower than noise setting value under the selected pattern, the amount that it can the display noise value.When the ambient noise value meets or exceeds noise setting value under the selected pattern, it will start the warning lamp prompting function.(3) setting of warning lamp: whether the more intuitive reminding user ambient noise of this function surpasses the pattern setting value, supervises the user to leave noise source or takes to fall low noise behave, protects the hearing of oneself.Working at night especially, the situations such as sleep are more obvious to user's help meeting.Very hommization of the design of above three kinds of functions.Continuous noise figure is measured than timing detection noise value and is more produced effect, and plays the effect of constantly reminding.The setting of three kinds of patterns meets popular life characteristic, and the user of its three kinds different noise figure place of being set as varying environments provides better supervisory role.The design of warning lamp not only further intuitively reminding user neighbourhood noise of living in reach or be higher than setting value, also because it is visual signal but not other signals, avoided bothering the situation of surrounding population.
