Ear protection when listening to music

Scientists have successfully developed a device that will not damage your hearing: the red light will blink as you stand next to the deafening noise.

For example, if you are standing near a tractor and are afraid that the noise it emits can harm the ear. Just tap on the audio port of this handset and check the red light. Similarly, you can also check whether the music volume of your iPod is too loud or not.

According to the latest statistics, in the United States alone, about 33 million people have hearing impairments at levels, of which up to 22 million people are permanently damaged by an over-sized sound. "Maybe when you're young, your hearing is good, your ears will recover somewhat, but on many occasions, your hearing will definitely be lost," Webster warned.

"Sound from 85 decibels or more is in danger of being heard, but it's easy for the player to pass the threshold," he said. "We are seeing a growing number of young people with hearing impairment."

With the Ear3, the low beam flashes at an intensity of 85-90 decibels, rising gradually above 90 and blinking continuously at a fire intensity of over 100.
