Experimental models of acoustic stethoscopes were designed, constructed, and compared with conventional models in an attempt to combat background noise interference. Selected prototypes were evaluated by flight surgeons on aircraft carriers and in helicopters. None of the instruments were useful for auscultation in helicopter noise. In carrier noise, several of the new patterns appeared more effective than the standard stethoscopes procured by the Federal services. Promising lines of further development are being pursued.
