You have said so much before, so how long is the listening time for safe car Bluetooth speakers, radios, mobile phones and other digital devices? In fact, regarding this point, there is a clear time regulation in the World Health Organization. Among them, the safe listening time at 85 decibels is 8 hours, which is noisier.

At 90 decibels, the safe listening time is 2 hours and 30 minutes. This decibel is a decibel that you feel very noisy and will damage nerve cells. For example, this decibel is the sound of a lawn mower. It is better to listen less. At 95 decibels, that is, the complex sounds heard when driving a motorcycle, the time should be controlled at 47 minutes in this environment. 100 decibels, safe listening time is 15 minutes, this decibel is the noise of a pneumatic drill or a car horn. Many of my friends like to participate in rock concerts, but the decibels of such absolutely noisy concerts are basically 105 decibels. In this environment, the safe listening time is only 28 seconds. I like to go to such concerts. Friends of please control the time effectively!
The safe listening time of 120 decibels is only 9 seconds. This decibel is the sound made by the propeller of an airplane taking off, or the time made by the vuvuzela. Seeing this time, I really feel that those World Cup spectators are actually quite hard. Yes, let's summarize this time, friends should keep it in mind.

90 decibels-2 hours and 30 minutes
