Description

Technical Field

[0001] The utility model relates to the technical field of noise detection, and particularly relates to a portable environmental noise detection device. Background Art

[0002] With the development of society and the improvement of living standards, people's requirements for environmental quality are also getting higher and higher. Noise is a kind of sound that everyone hates. It not only affects people's physical and mental health but also has a negative impact on the quality of life.

[0003] In the existing noise detection technology, most use detection equipment fixed by the roadside for detection. However, this method is not convenient to carry during use, which limits its use in different scenarios. For example, a Chinese patent discloses "a portable environmental noise detection device" with the application number "CN202220062157.7". It uses a pulling belt to enable the user to lift the device or hang the detection device on the hand, facilitating the operator to carry the detection device. However, during use, since the microphone is located outside and is very easy to break, it may cause damage to the device. At the same time, the microphone is in the environment and is easily covered with dust, resulting in dust falling into the microphone, causing blockage of the microphone.
