Accepted Answer

Real Ear Aided Response (REAR)

Answer

Real Ear Unaided Response (REUR)

Answer

Real Ear Occluded Response (REOR)

Answer

Real Ear Saturation Response (RESR)

Question 4

What is the primary purpose of using a 2cc coupler when measuring hearing aid performance?

Accepted Answer

To standardize electroacoustic measurements in a controlled, repeatable cavity

Answer

To measure hearing aid output inside the patient's ear canal

Answer

To assess real-world hearing aid performance in noise

Answer

To determine the patient's loudness tolerance limits

Question 5

The Abbreviated Profile of Hearing Aid Benefit (APHAB) is best described as:

Accepted Answer

A validated self-report questionnaire assessing hearing aid benefit and residual disability

Answer

A method for measuring real ear hearing aid output

Answer

An electroacoustic test for hearing aid quality control

Answer

A prescriptive formula for calculating hearing aid gain settings

Question 6

During real ear measurement, the probe tube should be positioned approximately:

Accepted Answer

5–6 mm past the medial end of the hearing aid tip, within 5 mm of the eardrum

Answer

At the opening (entrance) of the ear canal

Answer

Directly touching the surface of the tympanic membrane

Answer

Outside the ear canal along the outer pinna

Question 7

Functional gain in hearing aid validation is defined as:

Accepted Answer

The difference in decibels between a patient's unaided and aided sound field thresholds

Answer

The electroacoustic gain of a hearing aid measured in a 2cc coupler

Answer

The maximum output level a hearing aid can produce

Answer

The patient's word recognition score improvement with amplification
