Question 1

Which hearing aid style places all components in the ear canal and offers the greatest cosmetic appeal but the least power?

Accepted Answer

Completely-in-canal (CIC)

Answer

The completely-in-canal (CIC) style sits entirely within the ear canal and is cosmetically discreet but is limited in output power and feature availability due to its small size.

Question 2

The NAL-NL2 prescriptive formula is based on the principle of:

Accepted Answer

Maximizing speech intelligibility while maintaining overall loudness at a normal level

Answer

NAL-NL2 prescribes gain to maximize speech intelligibility by emphasizing audibility of speech phonemes while keeping overall loudness comfortable and near normal.

Question 3

In aural rehabilitation, 'speechreading' supplements auditory information by using:

Accepted Answer

Visual cues from lips, face, and body language along with contextual cues

Answer

Speechreading integrates visual cues (lip movements, facial expressions, gestures) with residual auditory information and contextual knowledge to improve speech understanding.

Question 4

A patient with a sloping high-frequency sensorineural hearing loss is MOST likely to benefit from a hearing aid with:

Accepted Answer

Greater gain in high frequencies than low frequencies

Answer

A sloping high-frequency loss requires more gain at high frequencies where hearing is poorest, to restore audibility of high-frequency speech cues such as fricatives.

Question 5

The purpose of the vent in a custom earmold is to:

Accepted Answer

Allow low-frequency sound to bypass amplification and reduce occlusion

Answer

A vent allows low-frequency environmental sound to enter the ear canal directly, reducing occlusion and low-frequency amplification, and improving sound quality and comfort.
