Hearing testing is done with an instrument called an audiometer. Hearing testing with the Madsen Micromate 304 is easier and less expensive. The Madsen Micromate 304 is a low-cost portable screening audiometer capable of performing complete manual audiological screening tests, operating on battery or mains power. It is ideal for rapid threshold determination in schools, industry, the armed forces, etc., and weighs only one kilogram. Although alkaline batteries have a long life in the MICROMATE 304, the audiometer automatically switches itself off approximately 10 minutes after hearing testing use to conserve battery power.
