The Hazards of Noise Pollution
Noise can have adverse physiological and psychological effects on the human body, with the degree of harm varying depending on volume, frequency, duration, and individual tolerance. The World Health Organization (WHO) provides an ideal daytime noise intensity range of 35-40 dB. Noise levels exceeding 50-60 dB can significantly disrupt daily life. In particular, sudden noise, while high in frequency and volume, can cause high-frequency hearing damage and even permanent deafness when the intensity reaches 120 dB or above, even though it lasts only a short time.
◉ Physiological and Psychological Effects of Noise
Noise, a sound that can cause physical and psychological discomfort, has a degree of harm depending on volume, frequency, duration, and individual tolerance. The World Health Organization (WHO) provides an ideal daytime noise intensity range of 35-40 dB. Noise levels exceeding 50-60 dB can significantly disrupt daily life.
◉ The Dangers of Sudden and High-Volume Noise
Sudden noise, in particular, is characterized by its high frequency and volume, though short-lived. However, when the intensity reaches 120dB or above, it can cause high-frequency hearing damage and even permanent deafness. Long-term exposure to noise levels above 90dB can not only cause tinnitus, increased blood pressure, vasoconstriction, and muscle tension, but can also lead to symptoms such as anxiety, irritability, headaches, and insomnia.
