What means listening for sounds within the body and it is usually performed through a stethoscope?
Main Body Show
The assessment technique of auscultation involves listening to the body. Although this is typically performed with a stethoscope, you can sometimes hear sounds from the body using just your ear. For example, you have probably heard your own or another person’s stomach growling; another example is heavy breathing after exercise. You can perform auscultation on the body to hear several sounds including:
To perform auscultation, you need a high-quality stethoscope. See Figure 1.10 for an acoustic stethoscope with a separate diaphragm on one side and a bell on the other side. The diaphragm is used for auscultating high-pitched sounds, while the bell is used for auscultating low-pitched sounds. Another option is an acoustic stethoscope in which the diaphragm and bell are manufactured as one piece: using this type of stethoscope, you can alternate pressure to auscultate for high- or low-pitched sounds, using light pressure to accentuate low-pitched sounds and firmer pressure to accentuate high-pitched sounds. There are also electronic stethoscopes to help amplify sounds for people with hearing loss. Some advanced stethoscopes facilitate better ambient noise reduction, sound amplification, and capability to record sounds (Leng et al., 2015). Unlike electronic stethoscopes, an acoustic stethoscope does not amplify the body’s sounds; it simply reduces interference from extraneous noises around you.

For example, findings may include “clear air entry bilaterally in all lobes” or “high-pitched gurgling bowel sounds present in all four quadrants.” How best to listen The best practice, supported by evidence, is to conduct assessments on bare skin. Always place the end piece of the stethoscope on bare skin, and never listen over the client’s gown or clothing as this can modify the sounds that you are hearing. In the clinical setting, you will witness many healthcare providers listening over clothing, but this is not the correct way to auscultate sounds. Substantial amounts of hair (e.g., on the chest, back or abdomen) can also create extraneous noise, making it difficult to hear the expected sounds. For infants, the best time to auscultate is while the infant is sleeping or quiet; if they start crying, encourage the care partner to console the infant by repositioning, breastfeeding/bottle, or soother (if permitted). If you are trying to auscultate the lungs of a young child, you could ask the child to take a big breath and pretend they are blowing bubbles or blowing out candles on a birthday cake. It is important to know the expected normal sounds and the abnormal sounds. You should trust what you are hearing. If you are struggling to identify the sounds you are hearing, try closing your eyes and focusing. If a sound is not normal, act on this and/or ask for a second opinion from your clinical instructor or preceptor. It is always good practice to listen to body sounds in partnership with an expert nurse. Activity: Check Your UnderstandingWhat term describes listening to the sounds body organs make when tapped?Introduction. Auscultation is the term for listening to the internal sounds of the body, usually using a stethoscope. Auscultation is performed for the purposes of examining the circulatory system and respiratory system (heart sounds and breath sounds), as well as the gastrointestinal system (bowel sounds).
