Autophony is the unusually loud hearing of a person's own voice.. Possible causes are: The "occlusion effect", caused by an object, such as an unvented hearing aid or a plug of ear wax, blocking the ear canal and reflecting sound vibration back towards the eardrum.
Patulous Eustachian tube is a physical disorder. The exact causes may vary depending on the person and are often unknown. [5] Weight loss is a commonly cited cause of the disorder due to the nature of the Eustachian tube itself and is associated with approximately one-third of reported cases. [6]
In his experiments, the subjects were discovered to be able to hear appropriately pulsed microwave radiation, from a distance of a few inches to hundreds of feet from the transmitter. In Frey's tests, a repetition rate of 50 Hz was used, with pulse width between 10–70 microseconds.
Video showing how sounds make their way from the source to the brain. Hearing, or auditory perception, is the ability to perceive sounds through an organ, such as an ear, by detecting vibrations as periodic changes in the pressure of a surrounding medium. [1] The academic field concerned with hearing is auditory science
Electronic fluency devices can be divided into two basic categories: Computerized feedback devices provide feedback on the physiological control of respiration and phonation, including loudness, vocal intensity and breathing patterns. [1] Altered auditory feedback (AAF) devices alter the speech signal so that speakers hear their voices differently.
The computer determines when the heart needs a jolt to get back on rhythm and delivers the electrical impulses back through the wires to the electrode, stimulating the heart muscle to contract.
Bone conduction is the conduction of sound to the inner ear primarily through the bones of the skull, allowing the hearer to perceive audio content even if the ear canal is blocked. Bone conduction transmission occurs constantly as sound waves vibrate bone, specifically the bones in the skull, although it is hard for the average individual to ...
Frances Densmore and Blackfoot chief Mountain Chief working on a recording project of the Bureau of American Ethnology (1916).. Sound recording and reproduction is the electrical, mechanical, electronic, or digital inscription and re-creation of sound waves, such as spoken voice, singing, instrumental music, or sound effects.
