How do stethoscopes transmit sound?
The acoustic stethoscope operates on the transmission of sound from the chest piece, via air-filled hollow tubes, to the listener's ears. When the diaphragm is placed against the patient's skin, body sounds vibrate the diaphragm, creating acoustic pressure waves which then travel to the listener's ears.
How do stethoscopes amplify sound?
But how does the stethoscope work? The disc and the tube of the stethoscope amplify small sounds such as the sound of a patient's lungs, heart and other sounds inside the body, making them sound louder. The amplified sounds travel up the stethoscope's tube to the earpieces that the doctor listens through.
Why do stethoscopes have two sides?
The stethoscope has two different heads to receive sound, the bell and the diaphragm. The bell is used to detect low-frequency sounds and the diaphragm to detect high-frequency sounds.
How is a stethoscope made?
