AN2060: Audiometer Extreme

An Audiometer is a machine, which is used to determine the hearing loss in an individual. The audiometer must be capable of making all measurements quickly, precisely, with no discomfort to the patient. Pure Tone Audiometer works on the principle of presenting specific pure tone signals to the subject and determining the intensity at which they can barely hear these signals. Coming from India, where more than seventy percent of the population is rural, and the doctors attending to these masses have to often travel large distances on their two wheelers, warrants that the Audiometer be extremely portable and rugged. The Cyprus PSoC micro controller with its integrated analog and digital blocks is the right candidate for this kind of design. Using this micro controller it is possible to cut down on some of the support chips, thus automatically reducing the space and cost.
