Abstract
Recently, as wireless earphones are worn when using a smartphone, the risk of wireless earphones following the Earmbie(Earphone + Zombie) phenomenon has become a more serious social problem. In particular, When used the risk of using earphones with noise cancelling technology is even greater. This is because noise cancelling earphones are made to focus only on the sound heard through earphones because external noise is almost blocked. In this paper, we investigated the principle of noise cancelling earphones, and studied the dangers and prevention methods of wearing the noise cancelling earphones. Hearing test was performed as an experiment on risk. Hearing test was conducted by setting and wearing noise cancelling earphones when wearing both ears and when wearing one ear, listening to music with a normal beat, and listening to the horn and the surrounding distance noise. It is believed that this experiment will help to prevent dangerous situations when using noise cancelling earphones. As a result of the hearing test, the ambient sound could be detected when wearing one ear of the noise cancelling earphone, but almost could not detect the ambient sound when wearing both ears. The horn sound was a sudden and strong warning sound, so even when both ears were using noise cancelling earphones, it could be detected to some extent, but when listening to high-volume music with strong beats, even the loudest horn could not be recognized. . As a result of the experiment, in order to prevent the danger of noise cancelling earphones, noise cancelling earphones should be worn on both ears only in a safe state where you can comfortably concentrate on sound indoors. In addition, when going out on the street, it was found that only one ear should be worn, and the volume of the music or sound being heard should be set to a low level. The enjoyment of video and sound should be done within the range that can cope with the danger.
