| | This can be seen to be a result of their valence electrons being essentially free. | | | In the band theory, this is depicted as an overlap of the valence band and the conduction band so that at least a fraction of the valence electrons can move through the material. | | | In insulators the electrons in the valence band are separated by a large gap from the conduction band, in conductors like metals the valence band overlaps the conduction band, and in semiconductors there is a small enough gap between the valence and conduction bands that thermal or other excitations can bridge the gap. |

When the bone is vibrated in any location, the sound travels to both inner ears at almost the same time. | | | Instead of sending the sound out through the earmold, the signal travels through a wire leading to an oscillator, which vibrates. |
