HAC Hearing Aid Verification & Validation 3

Question 1

Which of the following is a validated outcome measure specifically designed to assess hearing aid benefit?

Accepted Answer

Glasgow Hearing Aid Benefit Profile (GHABP)

Answer

The Glasgow Hearing Aid Benefit Profile (GHABP) is a validated questionnaire measuring initial disability, hearing aid use, benefit, residual disability, and satisfaction specific to hearing aid outcomes.

Question 2

The Client Oriented Scale of Improvement (COSI) is administered:

Accepted Answer

Before and after hearing aid fitting to measure patient-identified listening goals and improvements

Answer

The COSI is completed before fitting (to establish individualized listening goals) and after fitting (to rate the degree of improvement and final ability in each goal situation).

Question 3

Real Ear Saturation Response (RESR) measures:

Accepted Answer

The maximum output of the hearing aid in the ear canal at a high-level input signal

Answer

RESR measures the maximum output of the hearing aid in the real ear at a high input level (typically 90 dB SPL), providing the real-ear equivalent of the OSPL90 coupler measurement.

Question 4

Aided audiogram testing conducted in a calibrated sound field is used to:

Accepted Answer

Assess the patient's hearing sensitivity thresholds while wearing their hearing aids

Answer

Aided sound field audiometry measures the patient's detection thresholds with hearing aids active, providing an estimate of the audibility achieved with amplification across frequencies.

Question 5

When fitting hearing aids for a young child, using RECD to verify the fitting offers which key advantage?

Accepted Answer

It allows accurate real ear performance prediction from coupler measurements without requiring cooperative probe tube placement in the ear

Answer

RECD-based verification allows clinicians to predict real ear hearing aid output from 2cc coupler data, avoiding the challenges of obtaining cooperative probe microphone measurements from young or uncooperative children.
