This attribute of a medium is increased at the distance between the molecules is decreased.
What is elasticity?
100
The pitch of a sound is described physically using hertz while the loudness of a sound is described physically using this.
What is the decibel?
100
Used to perform the first step in a diagnostic hearing evaluation and helps 'light the way'.
What is an otoscope?
100
The intensity recorded on the audiogram which is found using the 'down 10, up 5' technique.
What is threshold?
100
This test requires familiarity with the word list used whenever possible.
What is speech recognition threshold?
200
This is the result when air molecules move along the same axis as the wave itself when a force is applied.
What is a longitudinal wave?
200
Pure tones seldom occur in nature. Therefore, when we hear sounds we are typically listening to these.
What are complex sounds?
200
An important internal component in an audiometer which electronically increases and decreases the intensity of the stimulus.
What is an amplifier?
200
While air conduction thresholds are typically measured at six primary frequencies, bone conduction is measured at the same frequencies with the exception of this primary frequency.
What is 8000 Hz?
200
While no statically significant benefits of its use have been found, many audiologists use this when completing speech testing.
What is a carrier phrase?
300
The graphical way to help explain sound waves as they pass through the air.
What is a sine wave?
300
As an audiometer tests an individual's hearing sensitivity, it would stand to reason is would use this decibel reference.
What is hearing level?
300
Used to feed the test stimuli into the room rather than into the headphones.
What is sound field?
300
While the term used to describe one of these is physically impossible, it is often used erroneously.
What is a soundproof room?
300
The word list that contains all the phonetic elements of English discourse and each contain a consonant, followed by a dipthong, followed by another consonant are typically used for this evaluation.
What is speech recognition testing?
400
Cycles per second describe this aspect of sound which can be affected by mass and stiffness.
What is frequency?
400
The number of decibels of a sound above the threshold of a given individual.
What is sensation level?
400
The averaging voltmeter which is required for speech testing.
What is a volume units meter (VU meter)?
400
'Now', 'Yes' or 'I hear it' are acceptable forms of what?
What is a patient response?
400
The score of a patient who was able to repeat 18 out of 50 words on a speech recognition test correctly.
What is 36%?
500
To solve the formula for velocity (v=fw) you need to know 'v' represents velocity, 'f' represents frequency and 'w' represents this.
What is wavelength?
500
Made possible by the relative intensities of sounds and their times of arrival at the two ears.
What is localization?
500
Unlike insert and supra-aural headphones, this is a small plastic device where the output of the audiometer terminates.
What is a bone conduction oscillator?
500
Bone conduction is a complex process which involves these three phenomena.
What are inertial, distortional and osseotympanic conduction?
500
This test was designed to obtain an estimate of a patient's difficulty hearing in noise and is said to represent thier performance in the 'real world'.
