1. Many drivers like to turn up the volume while driving, and their bodies will sway involuntarily to the strong rhythm. Moderately loud music can cheer up drivers and get rid of fatigue, but excessive music can easily lead to car accidents. Medical experiments have proven that if the volume is too loud while driving, it will increase the burden on the hearing, distract the attention, and reduce the accuracy of judging the situation. The sound of normal speech is 40 to 50 decibels. Experiments show that when the volume is 75 decibels (equivalent to the feeling in a downtown area), the driver's error rate in judgment is 24; when the volume is 95 decibels, the error rate in judgment exceeds 40.

2. Enya, Secret Garden, Kenny. Many people like these types of songs. Ethereal music can easily put people into a meditative state. But if it is a sunny afternoon, or on a monotonous highway, and the driving time is more than an hour, listening to such music for a long time will inevitably produce a "hypnotic" effect.

3. After listening to one disc and want to change to another, or want to fast forward or rewind to the song they want to listen to, many drivers do it themselves while driving. This is unsafe, especially on the highway, and drivers must not be distracted. In fact, when driving in urban areas, you can change the disc while waiting for a red light. When driving at high speed, you can ask the person in the passenger seat to help, or you can change it when you rest at a service station.
