Many friends like to play music when driving and turn the sound very high. Is it good if the music is too high when driving? If the music is too loud, will it affect the driver's attention? What are the hazards of driving too loud music?
Research data show that if the noise exceeds 90 decibels, it is equivalent to being in a music bar or subway station, your eyes will protest. 90 dB noise will reduce the sensitivity of eyes to distinguish light; 115 DB noise can reduce the sensitivity of the eye to brightness by 20%. The greater the noise, the worse the clarity of things. If you play loud and fast-paced music in such a closed space as the carriage, the sound and the vibration of the car will work together, and the sound can easily reach 95 dB.
Although there are no relevant research data in China, the chief ophthalmologist of Beijing Hospital of the Ministry of health analyzed that when the eye looks at an object, it can see clearly when it is stationary than when it is moving. This is because when moving, the focusing function of the eyes will be affected and the visual contrast sensitivity will decrease. " If the driving speed is too fast, the adjustment ability of vision will be relatively reduced, and the focus of retina can not keep up, which will affect the accurate discrimination and judgment of vision on the size, shape, position, chroma and luminosity of image information. "
In addition, when driving a car, people must observe the surrounding conditions at any time and capture and identify the road condition information in time in order to drive safely. If the sound in the car is too loud or the rhythm is too fast, it is easy to make people's brain distracted and distracted, and can't fully observe the surrounding road information, thus burying potential safety hazards.
Therefore, it is suggested that the sound effect in the car must be controlled when driving. Do not choose rock music that is easy to make people restless or music that is easy to make people happy and sad, and music that is easy to make people emotionally unstable. It is best to play some songs that are conducive to mood relief, such as light music or piano music, so as to maintain a relaxed and pleasant mood and concentrate on driving.
