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. These were the first behind the ear hearing aids manufactured by the National Acoustic Laboraties (NAL) in Australia Body worn hearing aid consisting of separate pieces, one for each ear with attached ear mould, for one ear, in original box. Provided and manufactured by the NAL (National Acoustic Laboratories), part of the Commonwealth Department of Health. "NAL" in centre of stylised map of Australia. "COMMONWEALTH/DEPARTMENT OF HEALTH" on inside of box. "IV" and "F.McD/RIGHT" manually etched on hearing aid. "II" manually etched on other hearing aid. "CAL AID H" inscribed on inside edge of hearing aid.

This work forms part of the collection assembled by the historian Dorothy Rogers, that was donated to the Kew Historical Society by her son John Rogers in 2015. The manuscripts, photographs, maps, and documents were sourced by her from both family and local collections or produced as references for her print publications. Many were directly used by Rogers in writing ‘Lovely Old Homes of Kew’ (1961) and 'A History of Kew' (1973), or the numerous articles on local history that she produced for suburban newspapers. Most of the photographs in the collection include detailed annotations in her hand. The Rogers Collection provides a comprehensive insight into the working habits of a historian in the 1960s and 1970s. Together it forms the largest privately-donated collection within the archives of the Kew Historical Society.Document, issued by the Council for Scientific and Industrial Research [CSIRO], East Melbourne in 1944, terminating the employment of Mr. G.
