Description

Device for reducing noise The present disclosure relates to a device, specifically to a device for reducing noise generated during dental treatment. With the advancement of technology, audio devices such as earphones and headphones recently include noise-canceling features. Noise can refer to a signal or a wave corresponding to a signal that the user does not want. Noise canceling technology includes methods to eliminate noise by physically blocking noise transmitted to the user's ears or by canceling out wavelengths generated from the noise signal source. This noise-canceling technology is not only applied to devices like earphones, but is also recently being used to block noise generated during dental treatments. However, since noise generated during dental treatment includes not only waves transmitted through the air like general noise but also waves generated within the human body, it is necessary to develop blocking technology for noise generated within the human body in order to effectively block noise from dental treatment.
