A 44-year-old member asked:
Why do we usually not hear the sound of our heart beating if it's constant?

Noise: The sound of our heart beat is muffled by many structures below the chest wall including chest muscles, fat, bone and connective tissue. Some people can hear the heart beat faintly when in a very quiet setting however usually you need an aid, like a stethoscope. Ambient noise around us also makes it difficult to hear our heart beats.
