Which of the following parameters best predict successful use of hearing aids?
++
++
++
A. MCL and word recognition scores
++
++
++
++
++
++
D. Word recognition scores and dynamic range
++
++
++
++
++
Which of the following can be used for rehabilitation of single-sided deafness? Choose all that apply.
++
++
++
A. Conventional hearing aid
++
++
++
++
++
++
D. Osseointegrated bone conduction system (Ponto, Baha)
++
++
E. Piezoelectric implantable hearing device
++
++
++
All of the following are advantages of behind-the-ear (BTE) style hearing aids compared to other styles, except
++
++
++
A. Can accommodate directional microphones
++
++
B. Can allow larger venting, accommodates a wide range of hearing losses
++
++
C. Easy to manipulate controls, easy to incorporate switches and volume control
++
++
D. Preferred in children because only the earmold has to be replaced as the child grows
++
++
++
++
++
All of the following statements regarding hearing amplification are true, except
++
++
++
A. OSPL-90 measures the output of a hearing aid when the input is low at a mere 10 dB.
++
++
B. The larger the dynamic range of an ear, the easier it is to fit a comfortable hearing aid.
++
++
C. Large venting improves hearing in noise but is contraindicated in ears with significant low-frequency hearing loss.
++
++
D. Methods for rehabilitation of single-sided deafness depend on transferring sound energy from the deaf ear to the contralateral healthy cochlea.
++
++
E. Patients with implantable hearing devices generally report increased sound fidelity (compared to their conventional hearing aids), reduced feedback problems, and no occlusion effect.
++
++
++
The following statements regarding ossiculoplasty are true, except
++
++
++
A. Postoperative hearing results are generally better with partial prostheses (PORP) than with total prostheses (TORP).
++
++
B. The middle ear provides an impedance matching mechanism between the air-filled external canal and the fluid-filled labyrinth.
