(PhysOrg.com) -- Scientists from Lawrence Berkeley National Laboratory have succeeded in using 3D optical scanning technology to effectively lift the voices from 125 year old recordings created by researchers working in Alexander Graham Bells Volta laboratory. The recordings were made on various media as researchers tried to improve the sound quality of Thomas Edisons recently invented phonograph.
