The occlusion effect occurs when an object fills the outer portion of a person's ear canal, causing that person to perceive echo-like "hollow" or "booming" sounds generated from their own voice. The bone-conducted sound travels to the cochlea through different pathways.
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.
This echoic sound resonates in the mind and is replayed for this brief amount of time shortly after being heard. [4] Echoic memory encodes only moderately primitive aspects of the stimuli, for example pitch, which specifies localization to the non-association brain regions.
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]
Echolalia is the unsolicited repetition of vocalizations made by another person; when repeated by the same person, it is called palilalia.In its profound form it is automatic and effortless.
The precedence effect or law of the first wavefront is a binaural psychoacoustical effect concerning sound reflection and the perception of echoes.When two versions of the same sound presented are separated by a sufficiently short time delay (below the listener's echo threshold), listeners perceive a single auditory event; its perceived spatial location is dominated by the location of the ...
Negative indicate the echo is stronger than the original signal, which if left unchecked would cause audio feedback. The performance of an echo canceller is measured in echo return loss enhancement (ERLE), [3] [9] which is the amount of additional signal loss applied by the echo canceller. Most echo cancellers are able to apply 18 to 35 dB ERLE.
Echophenomenon (also known as echo phenomenon; from Ancient Greek ἠχώ (ēkhṓ) "echo, reflected sound") is "automatic imitative actions without explicit awareness" [1] or pathological repetitions of external stimuli or activities, actions, sounds, or phrases, indicative of an underlying disorder.
