Bone Conduction Communication System ?Bone Conduction (BC) could be used for two-way communication systems in extremely noisy environments which require hearing protection devices in the ear-canals. A report on ScienceDaily says new technology to hear vibrations through the skull bone has been developed at Chalmers University of Technology. Besides investigating the function of a new implantable bone conduction hearing aid, Sabine Reinfeldt has studied the sensitivity for bone conducted sound and also examined the possibilities for a two-way communication system that is utilizing bone conduction in noisy environments. In two-way communication systems, Bone Conduction (BC) is believed to improve the sound quality when used in extremely noisy environments which require hearing protection devices in the ear-canals. Several studies were performed to investigate the possibilities for a BC communication system and to increase the general knowledge of BC sound perception. The low-frequency increase in perceived BC sound when wearing ear-plugs and/or ear-muffs is called the occlusion effect. This effect was studied by different methods and it was found that it is lower for deeper insertion of ear-plugs and for larger ear-muffs, and that it varies for different stimulations.
