The value of visual methods has been demonstrated in many technical fields. Percussion, palpation and auscultation, being tactile and aural methods, are handicapped both in the classroom and the clinic because of the lack of convenient and reliable methods for demonstrating the vibrations. Our teaching of physical diagnosis contains too many words which fail in the attempt to describe sounds heard in the chest. These words are apt to lack descriptive value in themselves and our further attempts at describing the sounds we hear too often demonstrate how...Bibliography1.
