Abstract
Current interest in the clinical evaluation of hearing at high frequencies (greater than 8000 Hz), and scarcity of low cost commercial units prompted us to investigate the feasibility of assembling an extended range audiometer. A search of the electronic components and earphones available in the market indicated that an extended range audiometer could be assembled with considerable savings on the cost. The audiometer under consideration is designed for measuring pure tone thresholds at standard 13 octave intervals in the frequency range of 100 through 25 000 Hz. Preliminary results on the audiometer performance will be presented.
