Abstract

The invention discloses an environmental noise detection device, which relates to the technical field of noise detection equipment. The environmental noise detection device comprises a noise detection device main body, the top of the noise detection device main body is provided with a detection probe, and the outer surface of the noise detection device main body is wrapped with an anti-interference noise reduction mechanism. The inner surface of the anti-interference noise reduction mechanism is tightly attached to the outer surface of the noise detection device main body. Energy in noise is absorbed through the sound absorption interlayer and the damping columns, meanwhile, the high density characteristic of the damping columns is utilized, the reflection curvature of the noise is reduced, then secondary weakening is conducted on the energy carried in the noise through the hollow attenuation columns and the energy absorption hole cavities, the attenuated noise energy is absorbed through the energy attenuation cavities and the sound absorption table grains, noise reflection is prevented from interfering with the detection effect, the problem that the noise detection precision of the device is affected due to the fact that a shell and other accessories of the device reflect noise is avoided, the utilization efficiency of the device is improved, and the noise detection precision of the device is guaranteed.

Description

technical field [0001] The invention relates to a detection device, relates to the technical field of noise detection equipment, and in particular to an environmental noise detection device. Background technique [0002] From the point of view of physics: Noise is the sound made by the sounding body when it vibrates irregularly. It should not exist in a certain environment. It generally refers to noisy and harsh sounds. The sound of people's normal rest, study and work, as well as the sound that interferes with the sound that people want to listen to, are all noise, so the use of equipment for noise inspection is becoming more and more frequent. [0003] There are following problems at prior art: [0004] 1. When the existing noise detection device detects the noise, the shell and other accessories of the device will reflect the noise, which will affect the noise detection accuracy of the device, resulting in a decrease in the utilization efficiency of the device and a decr...
