A kind of novel sound insulation cover soundproof effect detection device
Technical field
The present invention relates to blimp auxiliary device technical field, specially a kind of novel sound insulation cover soundproof effect detection dress
It sets.
Background technique
Today's society, various mechanical equipments are full of in every field and environment, and will generate machine when the operation of these equipment
Sound specific to tool, wherein sound when some equipment are run is larger, and at this moment mechanical equipment inherently becomes noise source,
Even the little equipment of some operation sound, equally possible for different people to become noise, people can be thus given
Normal life and work bring environmental pollution, be environment environmental protection peace and quiet for the sake of, people are often completely cut off using blimp
Noise, blimp can build the good cell of sound insulation value in local environment, to keep the sound inside and outside blimp strong
Degree is different, to reach sound insulation purpose to facilitate normal production and living.
Although there are many occasion workable for blimp, answered in some high-end equipment manufacturings and intelligence manufacture
With, but people can not do a specific judgement to the soundproof effect of blimp, often by human ear to sound insulation before and after
Intensity of sound compares, but if when testing blimp soundproof effect, it, must can not for the relative precision of test result
The intensity of sound work before and after sound insulation is judged with human ear by more people less, then be drawn a conclusion, but because different people is listened
Feel is different, therefore its test result is often with subjectivity and inaccuracy.Also there is the inspection of some blimps in the market
Device is surveyed, but this kind of device may result in sound leakage excessively at source of sound, so as to cause detection inaccuracy.
