Telephones Info

The Telephone come from the Greek words tele = far and phone = voice. It is a telecommunications device that is used to transmit and receive sound. The Telephone is now one of the most common household appliances in the world today. Nearly all telephones operate through transmission of electric signals through a complex network which allows any phone number to communicate with another anywhere in the world. The Telephone runs two types of information; Signal and Voice, at different times all on the same two wires. The telephones signal equipment consists of a bell to alert the user of incoming calls and a keypad to enter the number for outgoing calls. At the telephone exchange they detect the electrical current and connects the line to the desired line and alerts that line. The Voice part of a telephone is in the handset and consists of a microphone and a receiver. The microphone is powered from the line and puts out a varied electrical current in response to the acoustic pressure produced by your voice. The variations in electric current are sent along the line to the other telephone where they are fed into a miniature loudspeaker. The varying electric current in the coil causes it to move back and forth, reproducing the acoustic pressure waves of the transmitter. When you ‘hang up’ the current ceases to flow in that line, signaling to the exchange to disconnect the call. As with many other inventions over the years such as radio, the light bulb and the computer there were several people who claim credit for the invention of the telephone; many did do pioneering work on voice transmission and improved on each other’s ideas. Antonio Meucci, Johann Philipp Reis, Elisha Gray, Alexander Graham Bell, and Thomas Edison, among others, have all been credited with pioneer work on the telephone.

Headset Info

A headset is a headphone combined with a microphone. Headsets are widely used in call centres by people in telephone intensive jobs. The reason headset are used is because they supply the equivalent functionality as a telephone but with hands free operation. Most people use headsets at the computer so they can converse and type comfortably. Headset are not the same as headphones, headphones are usually used for audio listening, whereas Headsets are designed purely for Communication. Headsets come in two distinct styles; single ear piece (monaural) and double ear piece (binaural). Binaural headsets do not play sound in stereo; the same audio comes out through both speakers. Many people choose to wear monaural headset so they can be more conscious of their surroundings. As telephones only offer a single channel input and output, all double ear piece headsets are binaural. There is also two major different microphone designs types; Omni-directional and noise-canceling. Noise cancelling microphone headsets use bi-directional microphones. A bi-directional microphone’s receptive field is two angles only. Its receptive field is limited to only the front and the direct opposite back of the microphone. This is the best method for only picking up sound from a close proximity, and not picking up background noise. Omni-directional microphone picks up sound from a complete 360-degree field. Sometimes when you require a higher sensitivity from the microphone or when the sound source is further away an Omni-directional microphone is better. Most voice tube headset designs employ an Omni-directional microphone, since the sound source needs to travel through the voice tube before it reaches the microphone. Headset can also be worn in different styles; over-the-head headsets with a headband over the head and over-the-ear or ear loop headset; these headsets do not have a headband and are worn over the ear with a soft ear hook.
