Accepted Answer

Noise Reduction Rating (NRR)

Answer

The EPA mandates the NRR labeling system on all HPDs sold in the US, providing consumers with a standardized measure of attenuation.

Question 2

When performing a biological calibration check of an audiometer, the clinician listens for pure tones at each frequency. The primary purpose is to detect:

Accepted Answer

Gross equipment malfunctions such as static, tone interruptions, or cross-talk

Answer

A daily listening check is a subjective biological calibration to identify obvious malfunctions like static, tone breaks, or channel cross-talk before patient testing.

Question 3

Which ANSI standard specifically addresses the specification and performance requirements for pure-tone audiometers?

Accepted Answer

ANSI S3.6

Answer

ANSI S3.6 (Specification for Audiometers) defines the electroacoustic performance requirements for diagnostic and screening audiometers.

Question 4

Electrical safety in audiology requires that audiometric equipment should be connected to what type of outlet to minimize risk of electrical shock to patients?

Accepted Answer

Properly grounded 3-prong outlet with GFCI in wet locations

Answer

Audiometric equipment must be plugged into properly grounded 3-prong outlets, with GFCI protection required in areas where water may be present to prevent electrical hazards.

Question 5

According to infection control guidelines, which component of an audiometer requires cleaning between patients to prevent disease transmission?

Accepted Answer

Earphone cushions, insert earphone tips, and bone vibrator surfaces

Answer

All patient-contact surfaces including earphone cushions, insert foam tips (single-use or disinfected), and bone vibrators must be cleaned/replaced between patients.
