Beautiful music can cultivate sentiment, cure diseases and prolong life, but music with strong sound, fast pace and high excitement is harmful to health. American experts found that crazy sound and rhythm can destroy the normal movement rhythm of human heart and blood vessels, and damage the heart. Chinese otologists pointed out that playing strong sound, fast-paced and highly exciting concerts all day can cause intersensory deafness. According to the measurement, the volume of rock music is 9 ~ 11 decibels, disco music is 14 ~ 114 decibels, and symphony is generally around 8 decibels. The international standard for noise-induced deafness is 9 decibels. Therefore, experts suggest that it is best to listen to less or no music with more percussion instruments, and the volume of home appliances should not be too loud, especially for pregnant women.
