Mixed Deck — All HAC Topics Flashcards

Which masking approach is used to prevent the test ear signal from crossing to the non-test ear during bone-conduction audiometry?

Answer: Contralateral masking with narrow-band noise

Narrow-band noise is presented to the non-test ear contralaterally to prevent cross-hearing during bone-conduction testing.

A patient's tinnitus changes in intensity when they clench their jaw or move their neck. This is most consistent with which tinnitus subtype?

Answer: Somatic tinnitus

Somatic tinnitus can be modulated by somatosensory inputs such as jaw clenching or head/neck movement, suggesting musculoskeletal involvement.

Under HIPAA, a hearing care professional may share a patient's audiogram with a referring physician without a separate authorization if:

Answer: The disclosure is for treatment purposes

HIPAA's treatment exception permits sharing protected health information among providers for the purpose of coordinating patient care without additional authorization.

What is the primary purpose of Pediatric Hearing Aid Fitting in Hearing Aid Certification?

Answer: Improving hearing outcomes and patient quality of life

Pediatric Hearing Aid Fitting focuses on improving hearing outcomes and enhancing patient quality of life.

How does ongoing follow-up support Tinnitus Management & Treatment in Hearing Aid Certification?

Answer: It ensures optimal performance and patient satisfaction over time

Regular follow-up ensures devices continue to perform well and patients remain satisfied with their hearing solutions.

A patient with a precipitous high-frequency hearing loss complains that amplified speech sounds 'tinny.' What adjustment should you consider first?

Answer: Reduce high-frequency gain

Reducing high-frequency gain lowers the perceived brightness/tinny quality that results from over-amplification of high frequencies relative to lows.

What does the term 'electrode array' refer to in a cochlear implant system?

Answer: The surgically implanted series of electrodes inserted into the cochlea

The electrode array is the flexible strand of electrodes inserted into the scala tympani of the cochlea to electrically stimulate the auditory nerve.

A parent reports that their toddler consistently removes the hearing aid. The FIRST recommended strategy is:

Answer: Use a retention device such as a clip or headband

Retention devices like huggies, clips, or headbands help keep hearing aids in place on young children who pull them off.

Which connectivity metric most directly affects the reliability of real-time remote hearing aid adjustments via manufacturer software?

Answer: Latency (ping)

Low latency ensures commands sent from the clinician's software reach the hearing aid fitting platform in real time without disruptive delays.

After cochlear implant activation, a patient reports hearing only beeps and no speech. The audiologist should:

Answer: Reassure the patient that auditory learning and cortical reorganization take time after activation

Initial sound perception post-activation is often unnatural; the brain requires time and auditory therapy to learn to interpret electrical signals as meaningful sound.

Which audiological finding would MOST warrant immediate referral to an otolaryngologist before proceeding with hearing aid fitting?

Answer: Conductive hearing loss with middle ear fluid seen on otoscopy

Conductive loss with middle ear effusion may be medically treatable, and a physician evaluation should occur before fitting amplification.

Pulsatile tinnitus that synchronizes with the heartbeat is most likely associated with which underlying condition?

Answer: Vascular or cardiovascular abnormalities

Pulsatile tinnitus synchronized with heartbeat is commonly caused by vascular abnormalities such as arteriovenous malformations, carotid stenosis, or benign intracranial hypertension.

During a follow-up appointment, a patient reports the hearing aid is comfortable in quiet but causes listening fatigue in noisy restaurants. Which feature adjustment is most appropriate?

Answer: Activate or strengthen directional microphone processing in the noise program

Directional microphone technology attenuates signals from the sides and rear, improving signal-to-noise ratio in noisy environments and reducing listening fatigue.

What is an open-fit dome in a RIC or slim-tube BTE hearing aid?

Answer: A small non-occluding tip that leaves much of the ear canal open, minimizing the occlusion effect

An open-fit dome leaves the ear canal largely unoccluded, reducing the occlusion effect and making it suitable for patients with normal or near-normal low-frequency hearing.

A patient calls the office two weeks after fitting, saying their hearing aids whistle when they hug people. What should the dispenser explain?

Answer: This is acoustic feedback caused by the microphone picking up amplified sound leaking from the ear canal

Acoustic feedback occurs when amplified sound escapes the ear canal and re-enters the microphone; fit adjustment or feedback suppression can resolve this.

A cochlear implant candidate has otosclerosis causing profound SNHL. What preoperative concern is most relevant?

Answer: Cochlear ossification that may impede full electrode insertion

Otosclerosis can lead to cochlear ossification, which may prevent full insertion of the electrode array and reduce outcomes.

What documentation is required for Tinnitus Management & Treatment in Hearing Aid Certification?

Answer: Assessment results, fitting parameters, patient preferences, and follow-up notes

Complete documentation includes assessment results, device parameters, patient preferences, and all follow-up interactions.

How has technology changed Types of Hearing Loss & Assessment in Hearing Aid Certification?

Answer: Improved precision, connectivity, and personalization options

Technology advances have improved precision, connectivity, and the ability to personalize hearing solutions.

What is a primary cosmetic advantage of a slim-tube BTE over a traditional BTE with standard earmold tubing?

Answer: The very thin, nearly transparent tube makes the device far less visible than standard thick earmold tubing

The slim tube is much thinner and less conspicuous than traditional earmold tubing, making the overall fitting less visible while still delivering sound to the ear.

A digital hearing aid's DSP uses an IIR filter. What does IIR stand for?

Answer: Infinite Impulse Response

IIR (Infinite Impulse Response) filters use feedback in their design, allowing efficient implementation with fewer coefficients than FIR filters for equivalent performance.
