Hearing Conservation Knowledge Quiz

 

1) When is a company required to implement an effective hearing conservation program?
a) a) When noise levels in a work area exceed 90 dBA.
b) When an employee in the workplace is exposed to 90 dbA of noise.
c) When an employee is exposed to a noise dose of 85db TWA.
d) When an employee is exposed to noise levels greater than 80 db A.


2) Parts (a) and (b) of  Occupational Noise Standard, 1910.95 define occupational noise exposure. Part (c)  of this standard defines what additional element?
a) Hearing Conservation
b) Permissible exposure limits
c) Administrative controls
d) Engineering controls

3) By what specific date were baseline audiograms initially to be completed?
a) March 1, 1974
b) April 1, 1974
c) March 1, 1984
d) April 1, 1984

4) When is the baseline audiogram updated?
a) Never
b) Whenever there is an STS
c) Only when advised by  the supervising  physician or audiologist
d) Whenever there is an improvement

5) A standard threshold shift is a change in hearing threshold relative to the baseline audiogram of an average of 10dB or more at what frequencies?
a) 500, 1000 and 2000 Hz.
b) 1000,  2000, and 3000 Hz.
c) 2000, 3000, and 4000 Hz.
d) 3000, 4000 and 6000 Hz.

6) At what level might a confirmed job-related STS become OSHA recordable?
a) Whenever  a change in threshold relative to the baseline audiogram is an average of 25dB or more at 2K, 3K and 4K Hz. Presbycusis adjustments are not included in the 25db HTL calculation.
b) Whenever  a change in threshold relative to the baseline audiogram is an average of 10dB or more at 2K, 3K and 4K Hz. Presbycusis adjustments may be  included in the 25db HTL calculation.
c) Whenever  a change in threshold relative to the baseline audiogram is an average of 10dB or more at 2K, 3K and 4K Hz. and when the average at 2K, 3K and 4K Hz. is at or greater that 25dB HTL. Presbycusis adjustments are not included in the 25db HTL calculation.
d) Whenever  a change in threshold relative to the baseline audiogram is an average of 10dB or more at 2K, 3K and 4K Hz. and when the average at 2K, 3K and 4K Hz. is at or greater that 25dB HTL. Presbycusis adjustments may be  included in the 25db HTL calculation.

7) An employee tested in 2004 has a confirmed job-related OSHA recordable shift indicates a permanent change in the left ear.  His initial baseline audiogram for both ears was 1989. His previously revised baseline date for both ears was 1998. The right ear has not had a recordable shift.  Your supervising physician tells you to update the employee's baseline audiogram. The baseline dates for the right and left ears would be:
a) 2004 for both ears
b) 2004 for the left ear; 1998 for his right ear.
c)1998 for both ears
d) 2004 for the left ear; 1989 for his right ear.

8) The employer is required to retain all employee audiometric test records for the duration of the affected employee's employment. In addition to the employee's name and audiometric results,  the audiometric test record must also include:
a) The examiner's CAOHC certification number
b) Employee's most recent noise exposure assessment
c) The NRR value of the employee's hearing protection
d) All of the above

9) The employer shall institute a training program for all employees who are exposed to noise.  How often must this training program be repeated?
a) Only once, but within 6-months of an employee's hire date.
b) Only once, but within 1 year of an employee's hire date.
c) Annually
d) Bi-annually

10) If a comparison of the annual audiogram to the baseline audiogram indicates a standard threshold shift, the employee shall be notified in writing within
a) 10 days of the determination
b) 21 days of the determination
c) 30 days of the determination
