The first commercial digital hearing aid was created in 1987 by the Nicolet Corporation. The hearing aid contained a body-worn processor that had a hardwire connection with an ear mounted transducer. While the Nicolet Corporation’s hearing aid was not publicly successful and the company shortly folded, it was able to start a competition between companies to create more effective hearing aids. Two years later, in 1989, the behind-the-ear (BTE) digital hearing aid was launched. In addition to the Nicolet Corporation, Bell Laboratories expanded upon the hearing aid business by developing a hybrid digital-analog hearing aid. When the hearing aid was put on in the market, it was instantaneously successful. This development helped bring major changes to the world of the hearing aid. The next major milestone was creating an all-digital hearing aid. The Oticon Company developed the first digital hearing aid in 1995, but it was only distributed to audiological research centers for research on digital technology in the realm of acoustic amplification. The Senso was the first commercially successful, all-digital hearing aid, and was created by Widex in 1996. After the success of the Senso, Oticon began marketing their own hearing aid, the DigiFocus. Presently, the digital hearing aid is now become programmable. By making the hearing aid programmable, it has allowed hearing aids to be capable of regulating sound on their own, without using a separate control. The hearing aid can now adjust itself depending on what environment it is in and often does not even need a physical volume control button. Silver metal case with side clips and hearing aid attached. Has battery compartment for AA batteries. Volume control is the top left hand corner. Comes with its black case "C OF A/CALAID/101862" on back of case. "ANGUS & COOTE/Acoustics/HEARING AIDS" on inside cover of case

The box is cleverly designed to give quick access to the parts inside, having a lift-up lid and a pull-down front. The components within appear to be a portable radio, power supply or power converter with batteries and a charger. The attached leather strap makes the equipment easily portable. The portable power supply is significant for representing part of the evolutionary change in communications. The unit connects the use of power and radio for communication with the ability to save the power in power packs or batteries, or to convert the power from one form to another.Power supply, portable, electric; circuits can be Parallel or Series. Batteries (6) fitted into a square wooden box. Box has two catches to secure the lid and two catches to secure the drop-down front. Holes have been drilled around the edges of the lid and the top of the base. Inside the front panel are two copper coils, switches and connectors. Leather carry strap attached. Stamped into the vertical panel are "parallel", "P", "H", "SERIES", CAVERTY", "LIGHT" :WEAK", "CHARGING" Stamped into the vertical panel are "parallel", "P", "H", "SERIES", CAVERTY", "LIGHT" :WEAK", "CHARGING" flagstaff hill, flagstaff hill maritime museum and village, warrnambool, maritime museum, maritime village, great ocean road, portable power supply, power supply, battery box, battery, communication, radio, portable radio, battery powered radio, electronic instrument

Until 1960 there were no telephones in Falls Creek. The only access to a phone was at Rocky Valley Camp where the State Electricity Commission (SEC) had an extensive network to Mount Beauty, Bogong and the other camps such as Clover power station and Howman's Gap. There were test points with a phone beside the road where contact could be made to the office in Mount Beauty. The SEC was unconcerned about Falls Creek, so no power was connected until 1960 when Tom Mitchell aired the matter in parliament. Tom was a keen skier. He applied to the Post Master General who was then responsible for telephones as well as mail. The PMG staff came up from Bright and installed an exchange in Diana Lodge. There were only about 15 lines to a post across the road uphill about 20 metres. It was from here that you could put a line from the building into a box where connections were possible. You had to buy a cable from the disposal store. It needed to have an alloy of copper and steel in the wire similar to what the army had used during the war. If the phone failed the owner would have to find the break in the wire, not an easy task in the heavy snow. Then came the telephone itself. Falls Creek was given old-fashioned sets with a hand wound magneto to ring the bell at the exchange. When the operator answered she could then plug a line into another phone line or the exchange in Bright. In the phone were two dry cell batteries that carried the spoken word to the other phone connected. Trunk lines were expensive then, so each trunk call was timed by the minute. The operator would disconnect you after a minute if you did not reply to her question "are you extending?". These telephones were donated by Julian Newton Brown. Julian's Lodge Arundel was known as Falls Creek 11.These telephones are significant because they illustrate the earliest form of technology available to connect Falls Creek Village to other areas.Telephones constructed of polished wood, brass bell, handles and cabling. Designed to operate through a telephone exchange. They operated on two dry cell batteries.Attached to front of telephone: Instructions on how to make or receive a call.falls creek village, falls creek communicaton

Erection of new butts by the members of the St Kilda Volunteer Army Corps in 1874, after the government took possession of the land that the Volunteer Army Corps had been using. The butts were banks constructed of sand and earth, kept together with saplings, to create areas for shooting practice. They were constructed on the beach at Hobson's Bay, half a mile from the St Kilda jetty. An article about this appeared in the Illustrated Australian News for Home Readers on 25 February 1874, available on the National Library of Australia Trove site https://trove.nla.gov.au/newspaper/article/63105925.
