A noise reduction earplug not causing tinnitus comprises an earplug body (1). The earplug body (1) is formed by a soft plastic material. At least one pipe (2) with a slender and small caliber is disposed in the earplug body (1). Any one of the pipe (2) is hollow and openings at two ends are open, and any one of the pipe (2) is extended in the earplug body (1) in a shape of a spiral, a curve or a straight line. Any one of the pipe (2) keeps a slender and small air channel in the earplug body (1). The lender and small air channel can let air pass through and can also make air pressures inside and outside an auditory canal balanced, which helps to eliminate uncomfortable body feeling and the tinnitus that occur on a user. In addition, only a small amount of external sound is allowed to enter the auditory canal through the slender and small air channel, and therefore, most of the environmental sound can be blocked but not all of the external sound is blocked, and the user does not need to be worried about loss communication with the outside. The earplug is especially suitable for a person who is difficult to fall asleep due to snore.Linvention concerne un bouchon doreille pour la réduction du bruit qui ne provoque pas dacouphènes et comprend un corps (1).
