Diagnostic audiology: historical perspectives.

In summary, the modern era of diagnostic audiometry began with the era of loudness recruitment in the 1950s, followed closely by the era of acoustic impedance in the 1960s and 1970s and, most recently, the era of evoked potentials in the 1970s and early 1980s. Throughout this period, the era of speech audiometry has grown slowly but steadily. Jay Sanders has made important contributions in each of these areas, but his most important legacy will be the continuing contributions of his many dedicated and loyal students in the years to come.
