Speech B. Pain C. Time D. Loudness - ANS-- D. Loudness (decibels) Frequency = Pitch (Hertz) 'how often you threw the pitch' One correct color code for audiometer earphones is: A. Red for right. B. Blue for right. C. Red for left. D. Black for right. - ANS-- A. Red for right Blue for the Left Pure-tone screening audiometers should include the following frequencies: A. 250, 500, 1000, 2000, 4000, and 6000 Hz. B. 750, 1000, 2000, and 4000 Hz. C. 500, 1000, and 2000 Hz. D. 1000 and 2000 Hz. - ANS-- A. 250, 500, 1000, 2000, 4000, and 6000 Hz. The ear is divided into three parts: A. Outer ear, middle ear, inner ear. B. External auditory canal, middle ear cavity, neural mechanism. C. Auricle, tympanum, neural mechanism. D. Outer ear, middle ear, vestibular mechanism. - ANS-- A. Outer ear, middle ear, inner ear. The first frequency to be tested in the pure-tone sweep-check screen is: A. 500 Hz B. 1000 Hz C. 4000 Hz D. 6000 Hz - ANS-- B. 1000 Hz The following frequencies should be used for the pure-tone sweep-check screen: A. 250, 500, 1000, 2000, 4000, and 6000 Hz. B. 500, 1000, 2000, 4000, and 6000 Hz. C. 1000, 2000, and 4000 Hz. D. 1000, 2000, 4000, and 6000 Hz. - ANS-- C. 1000, 2000, and 4000 Hz. The most common cause of conductive hearing loss in young children is: A. German measles (Rubella). B. Otitis media (ear infection). C. Noise exposure. D. Ototoxic drugs. - ANS-- B. Otitis media (ear infection). The pure-tone sweep check screen should be done: A. Only on the right ear B. Only on the left ear C. On whichever ear the pure-tone sweep check screen results indicate there is a problem. D. Always on both ears. - ANS-- D. Always on both ears. The three types of hearing loss are: A. Conductive, sensorineural, mixed. B. Sensorineural, mixed, maximum. C. Mixed, conductive, substantial. D. Minimum, conductive, sensorineural. - ANS-- A. Conductive, sensorineural, mixed. The two physical attributes used to define a pure-tone are: A. Loud and soft. B. Pitch and quality. C. Intensity and hearing level. D. Frequency (Hz) and intensity (dB). - ANS-- D. Frequency (Hz) and intensity (dB). The type of sound used for hearing screening purposes is called a: A. Pure tone B. Hearing tone C. Alternating tone D. Level off tone - ANS-- A. Pure tone The unit of measure for intensity is: A. Hz (hertz) B. AP (alternating pressure) C. dB (decibel) D. HL (hearing level) - ANS-- C. dB (decibel) When noise in the screening environment does not permit screening at 25 dB intensity for the pure-tone sweep-check screen, you should: A. Instruct the child to listen for softer tones. B. Increase the screening level to one that can be easily heard. C. Use longer presentations of the tone so that the child can hear them better. D. Discontinue testing and relocate to a quieter area. - ANS-- D. Discontinue testing and relocate to a quieter area. Which of the following is not a symptom of hearing loss: A.
