Abstract
1, 030, 957. Phonendoscopes. CESKOSLOVENSKA AKADEMIE VED. April 6, 1964, No. 14031/64. Heading A5R. A phonendoscope comprises a sensing head 1 in which is a cavity 2 closed by a diaphragm 3, and connecting tubing 5, 6 communicating with the cavity, the tubing having a slot 7 opening to the outside air, the size of the slot being adjustable to provide for frequency selection. Adjustment of the slot is effected by rotating a shaped screen 8 which is integral with an outer part 9, air communicating with the slot through a gap 12 between the part 9 and the sensing head 1.
