The Sebir that created the Telephone


Around 1875, an eminent scientist, inventor, engineer and innovator Alexander Graham Bell was conducting research on sound and how to transmit it. As part of this work, he studied the workings of the human ear, noting that the eardrum vibrated in response to sound


Improve long distance communication between people


At its normal volume, the sound of speech does not carry very far


Distance communication between people was achieved through developing a telephone receiver that contained a vibrating metal diaphragm

People were now able to communicate over a distance because the sound volume of their speech was amplified by a receiver that acted like a human ear

Association Comment

Alexander Graham Bell 'associated' the ability of human ear to hear sound by vibrating and adapted it to create a vibrating metal diaphragm that could hear human speech

Historic Impact

As a result of the endeavours of Alexander Graham Bell, the telephone was invented
