Description
Technical field
The utility model relates to hardware & tools and manufactures field, particularly relates to a kind of portable multi-function noise measuring instrument.
Background technology
Noise refers to the sound that sounding body sends when doing random vibration.Sound is produced by the vibration of object, propagates in certain medium with the form of ripple.Usually said noise pollution refers to that people is what cause.From physiological point, every interference people rest, study and work and the sound to the sound generation interference that you will listen, namely unwanted sound, is referred to as noise.When noise on human and surrounding environment cause harmful effect, just form noise pollution.Since Industrial Revolution, the creation of various plant equipment and use, bring prosperity and progress to the mankind, but also create more and more and more and more stronger noise simultaneously.Noise not only can cause damage to hearing, can also bring out multiple carcinogenic fatal disease, also disturb to some extent the life and work of people.Greatly, even if people is in sleep, the sense of hearing also will bear the stimulation of noise in the sleep impact of noise on human.Noise can cause dreaminess, easily wakes up with a start, degradation under sleep quality, and the impact of unexpected noise on sleep is more outstanding.Noise can disturb talk, the working and learning of people.Experiment shows, the noise arrived in a sudden as people once disturbs, and the thought will losing for 4 seconds is concentrated.According to statistics, noise can make labour productivity reduce by 10 ~ 50%, and along with the increase of noise, error rate rises.As can be seen here, noise can disperse the notice of people, causes slow in reacting, easily tired, and work efficiency drop, error rate rises.Noise also can shelter safety signal, and as alerting signal and vehicle running signal etc., so that cause the accident, we measure noise for this reason, thus draw the solution to noise.
Summary of the invention
In order to solve the problem, it is simple that the utility model provides a kind of structure, and feature richness, is easy to carry, and can measure the size of noise when noise sends and can export the technical scheme of related data:
A kind of portable multi-function noise measuring instrument, comprise shell, LCDs, control panel, capacitance microphone, AC signal output interface, accumulator, the top of shell is provided with capacitance microphone, the front of shell is fixedly installed LCDs, the below of LCDs is provided with control panel, the side of shell is provided with AC signal output interface, be provided with accumulator at the back side of shell, LCDs, control panel, capacitance microphone and AC signal output interface are electrically connected by wire.
