Compared with the classic sound conduction method of generating sound waves through the diaphragm, bone conduction eliminates many steps of sound wave transmission and can achieve clear sound restoration in a noisy environment. Moreover, the sound waves will not affect others because of diffusing in the air. Headphones made using bone conduction technology are called bone conduction headphones, also known as bone conduction headphones, bone-sensing headphones, bone conduction headphones and bone sensor headphones.
