Hearing Aid Dispenser's Written Exam with 100% Correct Solutions Why do we perform audiometric tests? - CORRECT ANSWER-to determine the different characteristics of a hearing loss if one presents A hearing loss is characterized by what three descriptors? - CORRECT ANSWER-1. Type of hearing loss (conductive, sensorineural, mixed) 2. Degree of hearing loss (mild, moderate, etc) 3. Configuration of hearing loss or what the hearing loss looks like (ex: flat, rising, sloping, etc) Conduc...

What are the axes labels on an audiogram? : Frequency in Hz (across top) Intensity in dB HL (along side) What are the numeric divisions of degrees of severity in adults? : Normal = 0 -25 dB HL (Slight = 16 -25 dB HL) Mild = 26 - 40 dB HL Moderate = 41 - 55 dB HL Moderately Severe = 56 - 70 dB HL Severe = 71 - 90 db HL Profound = 91+ db HL What is hearing sensitivity? : A person's ability to detect sounds/ how softly you can hear sounds (volume control) 2 | P a g e What is hearin...

"hearing levels" used by audiometers are also known as "sound pressure levels": - false 29 CFR 1910.95 is an example of a standard, not a regulation: - false a sound level meter is used to calculate sound wave frequency: - false acoustic neuromas can manifest as an asymmetric or unilateral hearing loss: - true administrative controls to limit noise exposure to include: - limiting the time a worker spends at a noise source after rolling down a foam plug, you should wait 30 seconds befor...

Psychoacoustics Ans: -the study of psychological response to acoustical stimulation -how you process sound and speech and respond to it Threshold Ans: -a certain intensity above which the organism always responds to the stimulus and below which it never does -LOWER THRESHOLDS ARE BETTER!!! -not a uniform agreement across alls studies -Threshold varies from moment to moment because of internal and external factors -Thresholds can go down to -10 dB Calibration Ans: - does the number on...

Type of hearing loss (conductive, sensorineural, mixed) 2. Degree of hearing loss (mild, moderate, etc) 3. Configuration of hearing loss or what the hearing loss looks like (ex: flat, rising, sloping, etc) Conductive hearing loss - Answer-a loss that occurs when sound is NOT transmitted efficientl...
