It is Alexander Graham Bell who is well known for inventing the telephone. Though this eminent scientist died in 1922, you can still hear his voice. Thanks to a new technology that has brought a 128-year-old recording made by Graham Bell back to life.
The National Museum of American History has some of the earliest sound recordings in the world. The museum has been working to unleash the words. When the museum realized that it had Bell’s recording too within its collection, the museum enlisted a group of scientists to extract the sound.
Eventually Smithsonian magazine has reported that Smithsonian researchers have recovered the world’s first voice-mail; an audio recording of Alexander Graham Bell made on April 15, 1885 using a mixture of wax-and-cardboard disc.
According to Smithsonian, Bell worked on several different ways to record sound, including using foil, wax, glass, paper, plaster, metal, and cardboard. However, to capture Bell’s voice, the scientists used new 3D imaging technology to scan the disc and then transferred the information to a computer. Now the Smithsonian has released the audio of Graham Bell in which he is saying: “Hear my voice — Alexander Graham Bell.”
