Noises In Your Chest

The doctor hears some curious noises when he places the stethoscope against your chest. When the lungs are in a healthy condition, the medical gentleman hears a pleasant, breezy sound, soft in tone, as you draw in the breath and expel it. Should the instrument convey to his ear a gurgling or bubbling sound he takes a mental note of the fact that you are in what is known as the moist stage of bronchitis. In the dry stage of the same complaint, the sound is a whistling, wheezy one.

One of the signs of pneumonia is the crackling note that comes through the stethoscope. It is not unlike the sound that can be heard when your finger and thumb have touched a sticky substance and you first place them together and then part them, holding them close to your ear.

Doctors occasionally hear a dripping sound, and that indicates that air and water have got into some part of the chest where they have no right to be. Blow across a bottle, and you will produce a sound which is actually to be heard in your chest. it is caused in same way -  that is, by air passing over a cavity.
