Technical Field

The application relates to the technical field of noise protection, especially, relate to a separate noise structure and protective clothing.

Background

The harm of noise to the human body is systemic, and can cause changes in the auditory system and also affect the non-auditory system.

The early stages of these effects are mainly physiological changes, which can be caused by prolonged exposure to relatively intense noise. For example, excessive noise has obvious negative effects on the emotion and emotional state of people, and certain behavioral functions and neurological functions can be changed in a high-noise environment. Further studies have shown that prolonged noise exposure can cause immune system dysfunction, predispose individuals to infection by pathogenic microorganisms, cause skin or other ailments, and can also induce a variety of carcinogenic and fatal ailments. When the noise frequency is close to the natural frequency of the human abdomen, the abdominal organ and the endocrine system of the human body are damaged.

However, people working in noisy environments are usually protected from the auditory system only simply, for example by wearing sound-insulating ear bags or earplugs, which are local and do not provide an effective protection against the abdominal organs of the human body.
