Why bone conduction is better than air conduction in pure tone audiometry?
Wiki User
∙ 11y ago
Because bone is a denser medium, sound travels faster and stronger through it than through air. Bone conduction never gives the body time to process sound properly because the sound never hits the middle ear process where it can be filtered and buffered. Instead, the signal goes into the bone, often around the mastoid bone or the skull area, and then travels directly to the nervous system and the brain without ever being filtered or buffered.

What is intrinsic conductivity?
Intrinsic conduction is conduction in a pure semiconductor due to electrons moving from negative to positive and an equal number of holes moving in the opposite direction. referenced from Dan O'Regan "Real world leaving cert physics"
Is distilled water a good conductor or a poor conductor?
Distilled water is a poor conductor. For conduction in any liqiud it must have +ve and -ve charged ions. Water in pure state doesn't dissociate appreciably to give enough ions for electrical conduction. But when soluble ionic compounds are added to it, their ions help water molecules to dissociate and give more ions for good conduction.
Why does the electrical conductivity of pure metal decrease with temperature while that of semiconductors increases?
The conductivity depends on the passage of charged particles especially electrons. In metals electrons are easily available in conduction band and so its conductivity is high. As we increase the temperature then core of atoms vibrate largely. So with positive charge it could easily minimize the electrons in the conduction band and hence fall in conductivity In case of semiconductor there will be usually forbidden gap between valence band and conduction band. So conduction is poor at ordinary temperature. But as we increase temperature that would allow electrons to reach conduction band as covalent bonds get broken. Hence higher conductivity
Why is water a better insulator than conductor?
it depends on the degree of impurities it contains in it s pure state it is less conductive
What is the least count of an audiometer?
The LEAST count would be Zero (0). This is not trivial. There is an established standard for what Zero actually is, as a reference point in Air.BS EN ISO 389 (1997) "Acoustics. Standard reference zero for the calibration of pure tone air conduction audiometers"
What is the cpt code for pure tone audimentry conduction bone only?
There is no specific CPT code for "Pure tone audiometry (threshold); bone only". You can use the code 92553 (Pure tone audiometry (threshold); air and bone) with modifier 52.
Why 8kilohertz bone conduction is not checked in pure tone audiometry?
8Khz may need an intensity higher for people to perceive it during air conduction especially in adults, during bone conduction, an increase in intensity may provoke a tactile response and not the response from audibility.
What is the cpt code for pure-tone audiometry air and bone?
92553
What is the importance of carrying out otoscopy before carrying out pure tone audiometry?
otoscopy should be done before carrying out pure tone audiometry to see if the patient has impacted cerumen which can also cause hearing problem.
How is acoustic neuroma diagnosed?
Pure tone and speech audiometry are two screening tests that are often used to evaluate hearing. Pure tone audiometry tests to see how well someone can hear tones of different volume and pitch
What cpt code do you use for Hearing test using pure tone audiometry air only?
I think its 92552
What does Tone Mean and High Tone Mean mean in pure tone audiometry?
Tone means something that the author uses in a book.
Are ears made of pure bone?
they are made of cartilage.
Does conduction happen in fluids?
Guessing you mean electrical conduction. Yes, liquids can conduct electricity. Pure water is a poor conductor, water with impurities like salt water is an EXCELLENT conductor.
What is intrinsic conduction?
Intrinsic conduction is conduction in a pure semiconductor due to electrons moving from negative to positive and an equal number of holes moving in the opposite direction. referenced from Dan O'Regan "Real world leaving cert physics"
Is Ch3SH an electrolyte?
The pure gas is not an electrolyte. In water, it is an extremely weak acid so there would be a tiny bit of conduction.
What is the name bone of the tongue of the tongue?
There is no bonw in the tongue. The tongue is pure muscle
