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. "C OF A/CALAID/36778" on back of case deaf children australia, hearing aid, calaid

The Commonwealth Ericsson Wall Telephone was adopted in 1901 by the Post Master General as the standard magneto telephone throughout Australia. It was designated by the Australian Post Office as: "Telephone No.1 - Magneto Wall, Commonwealth Type" The No1 was widely used in country areas and new installations of this type continued throughout the 1920s. Although classified as obsolete in 1951, several were still in service in country areas into the mid-1960s before the phone systems were fully automated. The phone was originally connected to a 'party' line (several connections to a common wire), and the winder was turned in various combinations of long and short turns (being the codes unique to each individual connection) to alert the other party of an incoming call. Anyone could listen in on a party line, although courtesy prevented it occurring most of the time. Central telephone exchanges rendered the party line obsolete. Vintage wall telephone The case originally housed two No6 dry-cell batteries to power the speaker (early models used a pair of Leclanche-like wet-cell batteries - the drawing from 1911 indicates that wet-cell batteries were still in use at that time). Batteries became obsolete when the phone was connected to a central exchange. A plastic speaker horn was fitted in 2025 - the original was missing on front - L M ERICSSON & Co STOCKHOLM inside - serial number: 496018 H 5 (this serial number identifies the phone as being manufactured in 1904) inside - slip of paper identifies date of manufacture as 1904 inside aftermarket writing - F.W.31forests commission victoria (fcv), communications

Denis Gibbons (1937 – 2011) Trained with the Australian Army, before travelling to Vietnam in January 1966, Denis stayed with the 1st Australian Task Force in Nui Dat working as a photographer. For almost five years Gibbons toured with nine Australian infantry battalions, posting compelling war images from within many combat zones before being flown out in late November 1970 after sustaining injuries.
