Audiology Final Questions and Answers 100% correct 2023

Audiology Final Questions and Answers 100% correct 2023 The _____ of a sound wave is the number of cycles completed in one second of time. frequency In a sine wave, the point at which the molecules are very close together is called: compression Sound is transmitted through: D) outer ear tympanic membrane malleus incus stapes oval window hair cells. Which statement is incorrect: A) Intensity is related to loudness B) Frequency is related to pitch C) Pitch rises as the frequency of vibration increases D) Frequency is affected by length, mass, & tone D) Frequency is affected by length, mass, & tone True or False? The number of decibels of a sound above the threshold of a given individual is the sound's sensation level (SL) True True or False? Regarding the relationship of length with frequency, if the length decreases, the frequency increases (vibrations at a higher frequency). If the length increases, the frequency decreases True True or False? The distance the mass moves from the point of rest is called amplitude True True or False? Calibration of audiometers is performed every two years or sooner if a problem is identified False What is the difference between dB HL and dB SPL? HL= hearing level, we use term with regards to testing of hearing SPL= sound pressure level, how much sound pressure it takes to reach the hearing level at each frequency and often used to measure the sound in the environment with sound level meters Before conducting a hearing evaluation, an SLP or audiologist must check that the equipment: has been calibrated _________ earphones are best to use in noisy environments. Noise cancelation over insert earphones 3. Air conduction findings cannot: locate the specific site of damage. The results of air and bone conduction give information about the: type and severity of hearing loss. True or False? Audiometer transducers are color coded: red for right and blue for left. True True or False? Air conduction audiometry assesses the entire auditory pathway. True True or False? False negative responses tend to suggest that hearing is worse than it actually is. True True or False? The hearing thresholds obtained during testing represent the softest sound the patient is able to hear. True An example of a spondee is: heartburn Phonemically balanced lists are composed of: monosyllabic words. The __________ is often used during hearing aid fitting and adjustment. most comfortable listening level 4. The dynamic range refers to the difference between the __________ and the __________. speech recognition threshold; uncomfortable listening level Word discrimination testing is a measure of: clarity True or False? Audiologists use the same terms to describe speech audiometry testing. False True or False? Speech-language pathologists should understand the different terms used to describe speech audiometry tests because there is so much variability in the definition. True True or False? If a patient has moderate hearing loss by pure tone air conduction testing, speech recognition thresholds would be more severe. - pure tones and speech recognition thresholds should match False True or False? Before measuring the SRT, the clinician will familiarize the patient with the test words by word repetition or picture pointing. True True or False? Speech detection threshold requires a patient to recognize and repeat a speech stimuli, whereas speech recognition threshold measurements require that the patient acknowledges the presence of a speech signal with 50% accuracy. False True or False? The SDT is usually found at a more sensitive threshold level than the SRT. True True or False? To find the most comfortable listening level, the clinician adjusts the volume presented in the patient's headphones or the sound field while engaging in a conversation. - bracketing method True True or False? The term recruitment refers to a slight change in intensity resulting in a gradual increase in perceived loudness. False True or False? Uncomfortable listening level is an important part of hearing aid fitting and assessment. True True or False? A patient with an SRT of 30 dB and a UCL of 50 dB would be easier to fit for hearing aids than a patient who has an SRT of 15 dB and a UCL of 100 dB False - the first one is a very restrictive dynamic range very hard to fit but when greater dynamic range it is very easy to work with an individual True or False? WDT should be performed at 35-40 dB above the SRT. True Masking is needed to: prevent the better ear from compensating for the poorer ear. What masking noise is used for air and bone conduction? narrow band noise What type of masking noise is used speech testing? white noise True or False? Masking is needed to test each ear independently. True True or False? Interaural attenuation is the reduction in intensity, at one ear, of an acoustic stimulus presented to the other ear canal as the sound is transmitted through the head True True or False? Interaural attenuation levels differs for air and bone conduction True True or False? There are no issues with the amount of noise presented to the ear when masking False True or False? Under no circumstance is masking is not needed for speech False 1. The word immittance is used as an all-encompassing term to describe measurements of: A) tympanic membrane immittance B) compliance C) both A and B D) none of the above both A and B 2. Which tympanogram represents normal middle ear function? Type A 4. Electrophysiological measurements give audiologists information about the __________ cranial nerve and the brainstem. VIII
