A previous hum in Sausalito, California, also on the West Coast of the United States, was determined to be the mating call of the male midshipman. [37] However, in that case the hum was resonating through houseboat hulls and affecting the people living on those boats. In the West Seattle case, the University of Washington researcher determined ...
Venous hum is a benign auscultatory phenomenon caused by the normal flow of blood through the jugular veins. [1] At rest, 20% of cardiac output flows to the brain via the internal carotid and vertebral arteries; this drains via the internal jugular veins.
A hum is a sound made by producing a wordless tone with the mouth closed, forcing the sound to emerge from the nose. To hum is to produce such a sound, often with a melody. It is also associated with thoughtful absorption, 'hmm'. A hum has a particular timbre (or sound quality), usually a monotone or with slightly varying tones.
The earliest reliable reports of the Hum date from the Seventies, when numerous Bristol residents wrote letters to the Bristol Evening Post to complain about hearing the noise, which has since ...
Respiratory sounds, also known as lung sounds or breath sounds, are the specific sounds generated by the movement of air through the respiratory system. [1] These may be easily audible or identified through auscultation of the respiratory system through the lung fields with a stethoscope as well as from the spectral characteristics of lung sounds.

The torsional deflection of a simple cylinder cannot radiate efficiently acoustic noise, but with particular boundary conditions the stator can radiate acoustic noise under torque ripple excitation. [8] Structure-borne noise can also be generated by torque ripple when rotor shaft line vibrations propagate to the frame [9] and shaft line.
If certain problems are found, medical imaging, such as magnetic resonance imaging (MRI), may be performed. Other tests are suitable when tinnitus occurs with the same rhythm as the heartbeat. [3] Rarely, the sound may be heard by someone other than the patient by using a stethoscope, in which case it is known as "objective tinnitus". [3]
