Audiology Praxis Test Questions with 100% Correct Answers

Audiology Praxis Test Questions with 100% Correct Answers For which of the following instruments do national standards or uniform performance standards for calibration exist? a. Pure tone audiometers b. OAEs c. ABR d. all have calibration standards - Correct Answer ️️ -Pure tone audiometers Only pure tone audiometers have established (ANSI) standards for calibration Which is most likely to be introduced deliberately by an examiner during an audiometric exam? a. distorted tone b. switching transients c. masking noise d. none of the above - Correct Answer ️️ -Masking noise distorted tones are an error switching transients are sounds from turning a stimulus on/off (shouldn't exist) Sound requires a hearing mechanism to receive it. The other three necessary components include the following except: a. vibration b. medium c. force d. velocity - Correct Answer ️️ -Velocity Velocity isn't required for sound transmission It is a characteristic rather of medium, or the particles through which sound are traveling The outer ear is classified as what kind of device? a. Mechanical b. Acoustic c. Hydraulic d. Biological - Correct Answer ️️ -Acoustic The outer ear collects and funnels acoustic energy It doesn't perform mechanical movement It doesn't contain fluid like the inner ear It doesn't analyze sound energy and transmit it as an electrical impulse The middle ear is classified as what kind of device? a. Acoustic b. Mechanical c. Both of these d. Neither of these - Correct Answer ️️ -Both of these Tympanic membrane collects acoustic energy; the acoustic energy is transferred into mechanical energy through the ossicular chain The inner ear is classified as what kind of device? a. Mechanical b. Hydraulic c. Biological e. All of the above - Correct Answer ️️ -All of the above The hair cells mechanically transmit energy The endolymph (fluid) moves from incoming sound causing the movement of the hair cells It analyzes sound based on frequency and intensity and transmits that sound to the brain Without the middle ear, if sound reached the inner ear it would be a. virtually nonexistent b. so loud it would cause nerve damage c. distorted in frequency d. impossible to interpret - Correct Answer ️️ -Virtually nonexistent without the middle ear approx. 99.9% of sound would be reflected back to the atmosphere because the impedance of the inner ear is so much greater than that of the atmosphere The middle ear amplifies sound by approximately 17 times Which of the following is most likely to cause conductive hearing loss? a. presbycusis b. otitis media c. noise exposure d. birth trauma - Correct Answer ️️ -Otitis media middle ear infection causes swelling and fluid buildup in the middle ear space preventing sound to reach the inner ear chronic infections cause cause damage to the ossicular chain as well Which is most likely to cause sensorineural hearing loss? a. a foreign object b. impacted cerumen c. Meniere's disese d. serous otitis media - Correct Answer ️️ -Meniere's disease Fluctuating fluid buildup in the cochlea causes damages to the hair cells typically resulting in a low frequency HL Which is not a true statement of conductive and sensorineural hearing losses? a. Conductive hearing losses are often reversible b. sensorineural hearing losses are usually permanent c. sensorineural hearing losses impair discrimination d. conductive loss does not affect threshold level - Correct Answer ️️ -Conductive loss does not affect threshold level both conductive and SNHL impact threshold acuity A person with a hearing loss who suffers from recruitment will have a. difference in thresholds between ears b. less distance between audibility and uncomfortable loudness levels c. more distance between audibility and uncomfortable loudness levels d. overcompensation of the better ear for the more affected ear - Correct Answer ️️ - Less distance in dB between the hearing threshold and uncomfortable loudness level Which condition is most commonly associated with normal hearing? hyperacusis diplacusis presbycusis none of the above - Correct Answer ️️ -Hyperacusis Often associated with normal hearing, and can result from paralysis of the facial (VII) nerve which causes paralysis of the stapedius muscle! diplacusis is hearing the same sounds at different frequencies between ears presbycusis is age related hearing loss *The relationship of Hertz to sound waves to cycles per second equals: a. 1:10:100 b. 1:2:3 c. 1:1:1 d. 1:100:10 - Correct Answer ️️ -1:1:1 One cycle generates one sound wave Frequency (Hz) is determined by number of cycles per second A frequency of one cycle per second equals 1 Hz 1 Hz equals 1 sound wave and 1 cycle per second 1:1:1 *The human voice has a frequency range of approx. a. 50-500 Hz b. 6000-11,000 Hz c. 30-30,000 Hz d. 80-6000 Hz - Correct Answer ️️ -80-6000 Hz Most of the sound energy of human voices lies between 125-6000 Hz The peak of sound energy of the human voice is from Hz *In general the frequency range of human hearing is roughly a. 20-20,000 Hz b. 10-30,000 Hz c. 1-10,000 Hz d. 200-5,000 Hz - Correct Answer ️️ -20-20,000 Hz The human ear can hear frequencies below and above the typical range of the human voice NOTE: I'm not sure about humans hearing up to 20kHz but this is what the answer key states When using manual pure tone audiometry as part of a hearing loss prevention program, the frequencies that should be tested are: a. 250, 500, 1000, 2000, 3000, 4000, 5000 b. 500, 1000, 2000, 3000, 4000, 6000, and 8000 c. 1000, 2000, 3000, 40000, 6000, 8000, and 10,000 d. 800, 1000, 1200, 1400, 1600, 1800, and 2000 - Correct Answer ️️ -500, 1000, 2000, 3000, 4000, 6000, and 8000 If an individual has a low frequency hearing loss which fre
