CAOHC FINAL EXAM UPDATED ACTUAL Questions and CORRECT Answers
Impacted wax results in which type of hearing loss? Conductive
The purpose of the auto otoscopic exam by the OHSC is
Visually examine the ear canal for obstruction
to?
Noise causes which type of hearing loss? Sensorineural
Hearing loss from noise exposure is usually due to? Cochlear hair cell damage
the term pitch relates to Frequency
The range of normal human hearing at birth is? 20 HZ -20,000HZ
What is the most common threshold pattern for people
sloping\notched
who work in a noise environment ?
A standard threshold shift defined by OSHA as a 10 db average change in hearing at 2000, 3000,4000HZ
If the annual autograph shows a standard threshold shift
relative to the baseline OSHA requires the employer to 21 days of determination
notify the employee in the writing within how many days
According with OSHA which employees must receive
All employees exposed to 85 DBA TWA greater
mandatory annual hearing conservation training?
OSHA permissible exposure limit and exchange rate are 90 DBA TWA AND 5DB
According to the OSHA standard the permissible exposure
limit PEL is a noise dose of 100% this dose is equal to an 90 DBA
8 hours time weighted average off
If trying to identify a temporary threshold shift the best
At the end of the work shift
time to perform and audiogram is
Which of the followings is equivalent to noise exposure
95 dba for 4 hrs
exposure OF 90DBA for eight hours
The intensity dial of the audiometer control the decibel of
Decibel
the tone
The following is true about the relationship between OSHA
Nyasha makes recommendation OSHA is regulatory
and NIOSH
