Binaural hearing aid and method of reducing noise generated by touching hearing aid

A method of reducing noise generated by touching hearing aid, applied to a binaural hearing aid, for reducing a noise caused by an external object which is directly touching the left ear hearing aid or the right ear hearing aid, wherein the binaural hearing aid comprises a left ear hearing aid and a right ear hearing aid, the method of reducing noise generated by touching hearing aid comprising:

• obtaining a left ear sound received by the left ear hearing aid, and obtaining a right ear sound received by the right ear hearing aid;
• determining if a sound energy intensity difference between the left ear sound and the right ear sound is greater than an energy threshold;
• if the sound energy intensity difference is greater than the energy threshold, determining a larger energy intensity between the left ear sound and the right ear sound;
• if the left ear sound has the larger energy intensity than the right ear sound because the external object is directly touching the left ear hearing aid to cause the noise, replacing the left ear sound with the right ear sound such that the left ear hearing aid and the right ear hearing aid both output the right ear sound;
• and
• if the right ear sound has the larger energy intensity than the left ear sound because the external object is directly touching the right ear hearing aid to cause the noise, replacing the right ear sound with the left ear sound such that the left ear hearing aid and the right ear hearing aid both output the left ear sound.
