The Eckstein Tetra-Tone Audiometer, model 46, is a screening audiometer designed for use in medical offices for routine hearing tests as well as for public health, school and FAA hearing test programs. The unit provides the four most significant tones (500, 1000, 2000, and 4000 Hz) at intensity levels which correspond to normal hearing, mild, serious, and severe hearing losses. This instrument is also capable of making FAA hearing tests (Class I, II, and III).
