What harm does noise pollution do to humans? Industrial seismic isolators can effectively eliminate machine noise.

Noise pollution has many harms to humans:

1. Impact on physical health

Hearing loss

Long-term exposure to high-intensity noise environment can cause serious damage to human hearing. At first, it may manifest as hearing loss and tinnitus. If protective measures are not taken in time, it may develop into permanent hearing loss or even deafness. .

Impact on the cardiovascular system

Noise can cause high blood pressure and heart rate, increasing the risk of heart attack and stroke. Strong noise stimulation can make people's sympathetic nerves tense, leading to increased secretion of hormones such as adrenaline in the body, thereby causing vasoconstriction and increased blood pressure. Being in this state for a long time will cause chronic damage to the cardiovascular system.

Digestive system interference

Noise can cause gastrointestinal dysfunction, loss of appetite, indigestion, nausea and vomiting. Because noise affects the human nervous system, it interferes with the normal peristalsis of the gastrointestinal tract and the secretion of digestive juices.

2. Impact on mental health

Sleep disorders

Noise can interfere with people's sleep, leading to problems such as difficulty falling asleep, interrupted sleep, and dreaming.

Increased psychological pressure

Continuous noise can cause psychological pressure on people, making them feel nervous, anxious, and irritable. People who are in a noisy environment for a long time have a heavy psychological burden and are prone to emotional fluctuations and psychological problems.

Noise can affect people's attention, memory, and thinking ability.

 Industrial shock absorbers can effectively eliminate machine noise to a certain extent. The main reasons are as follows:

1. Reduce vibration transmission

The machine will generate vibrations during operation, and these vibrations will be transmitted through connecting parts, ground and other media, thereby generating noise. Industrial shock absorbers can absorb and buffer the vibration energy of the machine and reduce the transmission of vibration to the surrounding environment. For example, spring shock absorbers absorb vibration energy through the elastic deformation of the spring, and rubber shock absorbers use the high elasticity and damping characteristics of rubber to reduce the vibration amplitude. When the vibration of the machine is effectively controlled, the noise caused by vibration will also be greatly reduced.

2. Reduce structural noise

The vibration of the machine will cause resonance of the surrounding structure, thereby generating structural noise. Industrial shock absorbers can change the connection characteristics between the machine and the supporting structure, avoid the occurrence of resonance, and reduce the generation of structural noise. For example, when installing a machine, choosing a suitable shock absorber can adjust the natural frequency of the machine to keep it away from the frequency range that may cause resonance. This can effectively reduce the propagation of structural noise and reduce the noise level.

3. Improve machine stability

Industrial shock absorbers can also improve the stability of the machine and reduce the shaking and displacement of the machine during operation. When the machine runs more smoothly, the noise generated will also be reduced accordingly. For example, on some high-speed mechanical equipment, installing shock absorbers can reduce the vibration and shaking of the machine, improve the accuracy and reliability of the equipment, and also reduce the generation of noise.

However, it should be noted that industrial shock absorbers cannot completely eliminate machine noise. In practical applications, other noise reduction measures such as soundproof covers and mufflers need to be combined to achieve better noise reduction effects. In addition, it is also very important to choose the appropriate type and parameters of shock absorbers, which need to be comprehensively considered according to the characteristics of the machine, the working environment and the noise reduction requirements.
