Auscultation is usually done using a tool called a stethoscope. Health care providers routinely listen to a patient's lungs, heart, and intestines to evaluate the frequency, intensity, duration, number, and quality of sounds.
Health care providers also use auscultation to listen to the heart sounds of unborn infants. This can be performed with a stethoscope or with sound waves (called Doppler ultrasound). It can also be used to hear pulses in the arms and legs.
