To make a homemade Stethoscope.
Apparatus Required
A tubing piece
Scissors
A balloon
A timer
Rubber band
Procedure
Take a tubing and fit a funnel at both the ends.
Enlarge the balloon by blowing and then let the air out.
Cut top third of the balloon.
Stretch the top of the balloon tightly above the open end of any one of the funnels. You can use a band to hold it in the correct place.
Sit in a quiet place and keep the end of the funnel with a balloon on your chest, towards the left centre on the skin.
Keep the other funnel over the ear. You can hear a little beating sound.
Make use of the timer to count the number of beats you hear in 20 seconds. Multiply this value by three to calculate how much your heart beats in a minute.
Try doing more tests like running for 5 minutes and check how fast your heart beats.
The doctors listen to your heart beats for two seconds with a stethoscope. The first sound is a low pitched and longer sound while the second beat is higher and shorter sound.
Answer:
A stethoscope can be used to listen to the sounds made by the heart, lungs or intestines, as well as blood flow in arteries and veins. In combination with a manual sphygmomanometer, it is commonly used when measuring blood pressure.
