3. Basic concepts and impacts of noise pollution
3.1 Definition of noise pollution
Noise pollution refers to sounds that exist in the environment that have adverse effects on human life and work. Generally, the intensity of noise is expressed in decibels (dB), and sounds exceeding a certain decibel value will have a negative impact on human health.
3.2 Effects of Noise Pollution
The impact of noise pollution on humans is mainly reflected in the following aspects:
- Hearing Injury: Long-term exposure to high decibel noise environments may lead to hearing loss or even deafness.
- Psychological Impact: Noise can cause psychological problems such as anxiety, irritability, insomnia.
- Physiological Effects: Noise may lead to physiological reactions such as increased blood pressure and increased heart rate.
- Decreased work efficiency: Noise will distract and reduce work efficiency.
