Ultrasound can be perceived through bone conduction by the profoundly deaf as well as by normal-hearing subjects. Moreover, speech signals modulated onto ultrasound can be detected through bone conduction. This study explored how well listeners can understand ultrasonic speech and the confusion patterns to evaluate and improve bone-conducted ultrasonic hearing. The intelligibility of Japanese words classified by familiarity and Japanese monosyllables with bone-conducted ultrasound was investigated. Results showed that the intelligibility of familiar words was higher than that of unfamiliar words. Further, the results of a monosyllable intelligibility test with bone-conducted ultrasound and those of a test with air-conducted sound showed a similar pattern of speech recognition with regard to the errors made. The relationship between speech intelligibility and sound level showed that the increase in the intelligibility of bone-conducted ultrasonic speech did not exceed the increase in the intelligibility of air-conducted speech as the sound level rose.

If a hearing threshold were at 50 dB HL by air conduction and 5 dB HL by bone conduction what type of hearing loss exists?
Conductive, assuming the scores represent the same ear. The bone conduction is within normal limits while the air conduction score represents a mild to moderate loss.
What is the correct order of materials in the human body in increasing radiodensity air liver fat blood bone muscle?
air, fat, liver, blood, muscle, bone
Is the result of the transduction of air pressure waves into neural messages that are interpreted by the brain?
Hearing
How does chicken bone marrow differ from human bone marrow?
All birds have "hollow bones", they have air pockets in them to reduce weight.
An air space within a bone is called?
Foramen-An opening or orifice, as in a bone or in the covering of the ovule of a plant *American Heritage Dictionary
What is the difference conductive deafness and sensorineural deafness?
Conductive Loss - Normal hearing for bone conduction scores ([ & ]), and showing a hearing loss for Air Conduction scores (X &O) Sensorineural Loss- Hearing loss (equally) for both air and bone conduction
If a hearing threshold were at 50 dB HL by air conduction and 5 dB HL by bone conduction what type of hearing loss exists?
Conductive, assuming the scores represent the same ear. The bone conduction is within normal limits while the air conduction score represents a mild to moderate loss.
What is Rinne test?
a hearing test comparing perception of air and bone conduction in one ear with a tuning fork, normally air conduction is more acute
How can hearing be tested?
Hearing can be tested by a tests called audiometric tests, in which the patient is subjected to sounds of varying frequency and intensity and the amount of intensity that has to be raised above the normal level for that particular frequency is plotted on a chart.By this test, the threshold of hearing by air and bone conduction can be known and also type and degree of hearing loss can be assessed. There are various other clinical tests for hearing like finger friction test, watch test, voice test (these are obsolete now) and tuning fork tests- Weber's and Rinne's test.
What are the Hindu five senses?
Same as normal senses: sight, touch, taste, hearing, and smell. And the 5 basic elements are light, fire, water, air and earth
Use the expression to the bone in a sentence?
The air chilled to the bone.
How did the us use air power in Vietnam?
Strategic bombing was conducted over North Vietnam; tactical bombing was conducted in South Vietnam; Secret bombings were conducted in Laos and Cambodia.
What happens with someones hearing when the air pressure rises?
hearing becomes blarry and as if one is in high altitude
What is the meaning of sound?
Sound is a pressure wave in air or water at a frequency that can be captured and converted by the ear into a signal that can be perceived. Sound is anything that you can hear (if you have "normal" hearing). I may be seen as the same as noise.
Which country conducted air raids on Australia from 1942 until 1943?
japan
What is a air cavity in the bone?
Nasal or sinus
What is an air-filled bony cavity?
A sinus is an air cavity in bone.
