  • organ
  • Sensorineural hearing loss (SNHL) is a type of hearing loss, or deafness, in which the root cause lies in the inner ear or sensory organ (cochlea and associated structures) or the vestibulocochlear nerve (cranial nerve VIII) or neural part. (wikipedia.org)
  • Limits
  • For the creation of the series, the approximate threshold judged by a simpler method (i.e.: by the method of limits). (wikipedia.org)
  • In the vicinity of 20 and 20,000 cps (which are conveniently but arbitrarily called the "limits" of hearing), the threshold energy may rise to roughly 10 8 times the minimal value. (encyclopedia.com)
  • increases
  • As the measurements come closer to the absolute threshold, the variability of the noise increases causing the threshold to be obscured. (wikipedia.org)
  • These channels are shut when the membrane potential is near the (negative) resting potential of the cell, but they rapidly begin to open if the membrane increases to a precisely defined threshold voltage, depolarising the transmembrane potential. (wikipedia.org)
  • Under ideal laboratory conditions, humans can hear sound as low as 12 Hz and as high as 28 kHz, though the threshold increases sharply at 15 kHz in adults, corresponding to the last auditory channel of the cochlea. (wikipedia.org)
  • difference
  • The JND is a statistical, rather than an exact quantity: from trial to trial, the difference that a given person notices will vary somewhat, and it is therefore necessary to conduct many trials in order to determine the threshold. (wikipedia.org)
  • intensity
  • It is true, at least to a good approximation, of many but not all sensory dimensions, for example the brightness of lights, and the intensity and the pitch of sounds. (wikipedia.org)
  • Recognition
  • We tested early blind (n = 15), late blind (n = 15), and sighted (n = 30) participants with analogous olfactory and auditory tests in absolute threshold, discrimination, identification, episodic recognition, and metacognitive ability. (su.se)
  • nerves
  • The first has mixed sensory and motor nerves innervating swimmerets while the second has sensory and motor neurons that innervate the extensor muscles, while the third root contains only motor neuron projections that extend into the flexor muscles. (wikipedia.org)
  • detect
  • The threshold of hearing is set at around 0 phon on the equal-loudness contours (i.e. 20 micropascals, approximately the quietest sound a young healthy human can detect), but is standardised in an ANSI standard to 1 kHz. (wikipedia.org)
  • various
  • Because it fluctuates, the threshold is difficult to measure, and the various methods that have been tried do not always yield the same value. (encyclopedia.com)
  • effect
  • The demonstration that traces of sensory effect too slight to make any registry in consciousness could none the less influence judgment, may itself have been a persistent motive that induced me years later to undertake a book on The Subconscious. (wikipedia.org)
  • sense
  • It can be difficult to live with a child with sensory defensiveness (e. difficulty in interpreting a sense. (scribd.com)
  • example
  • A common cause or exacerbating factor in sensory hearing loss is prolonged exposure to environmental noise, for example, being in a loud workplace without wearing protection, or having headphones set to high volumes for a long period. (wikipedia.org)
  • energy
  • Of the energy that strikes the sensory surfaces of man and the animals, only a restricted fraction is capable of eliciting a reaction. (encyclopedia.com)
  • research
  • His research concluded that sensory nerves enter at the posterior (dorsal) roots of the spinal cord and motor nerves emerge from the anterior (ventral) roots of the spinal cord. (wikipedia.org)
  • Modern approaches to sensory perception, such as research on vision, hearing, or touch, measure what the perceiver's judgment extracts from the stimulus, often putting aside the question what sensations are being experienced. (wikipedia.org)
