How Many Decibels Does a Car Horn Produce?

[DiBrody]

A car horn can cause instantaneous noise levels to exceed 70 decibels and approach 80 decibels, while the horns of larger vehicles can surpass 80 decibels. Noise poses significant harm to humans, especially sudden bursts of noise. Many local governments have regulations on car horn volumes. For example, in Chongqing, motor vehicles are strictly prohibited from using horns with volumes exceeding 95 decibels. The hazards of noise include: 1. It can cause ear discomfort such as tinnitus, ear pain, and hearing damage. Studies show that noise exceeding 115 decibels can lead to deafness. Clinical medical statistics indicate that living in an environment with noise levels above 80 decibels can result in deafness in up to 50% of cases. Medical experts suggest that household noise is one of the causes of deafness in children. 2. It reduces work efficiency: Research has found that noise levels above 85 decibels can cause irritability and distraction, making it difficult to focus on work and thereby reducing efficiency. 3. It damages cardiovascular health: Noise is a risk factor for cardiovascular diseases, accelerating heart aging and increasing the incidence of myocardial infarction.
