With the advance of human society, along with the development of modern science and technology, people are faced with an increasing number of pollutions. One of the severe pollutions is noise pollution. Many parents express their complaints over noise pollution, especially car alarms.
Anchor
Almost anyone who has lived in a big city can tell you how irritating it is to be awakened in the middle of the night by the wail of a car alarm. The loss of sleep can drive you crazy, but this is just one in a long list of problems that such high decibel noises can cause.
Jonathan
People in this noisy neighborhood in upper Manhattan are fed up with car alarms. They're angry enough at being jolted awake several times a week, but more than that they worry about what effect these alarms will have on their children. Already studies have shown that continuous exposure to high-decibel noise can cause an increase in heart rate and blood pressure.
Andrea
By the time my child can read, he will already have been exposed to the constant roar of the traffic, but the intense siren of a car alarm is way above the level of safety.
Michael
I have a valid concern. According to the National Institute of Occupational Safety and Health (NIOSH), exposure to noise above 85 decibels for 8 hours or more is a danger to your health. City traffic and trucks are about 90 decibels. The siren of a car alarm is about 120 decibels, about the same as a plane taking off.
The parents here are sick and tired of listening to the shrill siren of car alarms. However, it's for their children that they are most concerned. They've started a group called Parents to Silence Car Alarms. They don't think that making the owner of a car pay a fine is enough. These parents have started a campaign to have car alarms banned.
