This is a traditional kung fu. Although it may be very powerful, it is unlikely to directly deaf people. Double wind penetration is a kind of move in which two palms attack at the same time, two palms scratch slightly and slam each other's ears. Although this kind of action can have a certain impact, it is usually not enough to directly cause deafness.

In competition or practice, we should pay attention to maintaining proper strength and skills to avoid causing serious harm to others. However, if it is used repeatedly or excessively, this attack may have a certain impact on hearing, such as tinnitus and deafness during long-term practice or competition. In addition, if the attack is strong enough, it may also cause damage to the eardrum, but it usually takes a lot of strength to achieve it.

Generally speaking, it is unlikely that a person will be deaf directly because of the double wind, but it should be used with caution to avoid excessive use.
