Communication, in one form or another, has long been a staple of existence. Each species has its own way to communicate. Sound, visual cues and touch are the most common forms of communication among humans. Other species use taste, smell and even the ability to observe wavelengths via thermal sensing. The Museum of Communications has documented the advances made in the way that humans communicate with each other. What started out as sound heard amongst individuals in a common area progressed to the ability to speak with someone halfway across the world.
Hundreds of years ago, people would have to wait many weeks for a message to be relayed to another person. Soon, it was discovered that an electrical telegraph could be used to transfer information from one person to another. Shortly after that, came the invention of the telephone followed by the photophone and then the radio. The Museum of Communications has artifacts showing the progression over the years. They also delve into the specifics behind the technology of the equipment used. Exhibits showing building terminals, splices, transmitters and wire recorders are all on display for public viewing.
Some forms of communication have developed simply due to a need. Long before medical doctors could treat problems such as hearing loss, people had to find a way for me to be meant through other forms of communicating. The same is true for animals. Although now many people have pet insurance to help with the cost when an animal has an eye injury, years ago the same animal would have had to find alternate ways to get their message across even with a loss of eyesight. Communication remains a way to share feelings, relay important information and address specific needs.
