[1] These sounds, such as one's own breathing, voice, and heartbeat, vibrate directly onto the ear drum and can create a "bucket on the head" effect, making it difficult for the patient to attend to environmental sounds.
Upon auscultation, this sign is an extra heart sound of to-and-fro character, typically with three components, two systolic and one diastolic.

Heart sounds are the noises generated by the beating heart and the resultant flow of blood through it. Specifically, the sounds reflect the turbulence created when the heart valves snap shut. In cardiac auscultation , an examiner may use a stethoscope to listen for these unique and distinct sounds that provide important auditory data regarding ...

The 'bottom-up' theory explains that unwanted external (from the environment) and internal (e.g., heartbeat) noise results in the subject only responding to the sound if the signal-to-noise ...

When listening to lungs, breath sounds such as wheezes, crepitations and crackles are identified. The gastrointestinal system is auscultated to note the presence of bowel ...
