---

1.  The Ponto Bone Anchored system consists of Implant, abutment, external sound processor Implant, abutment, soft band Implant, external sound processor, drilling equipment None of the above

2.  Which of the following is an indication for the Ponto bone anchored hearing system Single sided deafness Mixed hearing loss Conductive hearing loss All of the above

3.  3. Oticon Medical introduced the Ponto Bone Anchored System in 2011 2010 2009 None of the above

4.  One advantage of a bone anchored hearing processor over a bone conduction hearing aid is There is damping via skin Sound is transmitted indirectly via bone conduction Sound quality is natural None of the above

5.  The 2 main principles osseointegrated sound processors are based on are is based on: osseointegration direct bone condcution ossseointegration and direct bone condcution implant extrusion and direct bone conduction

6.  The two most common etiologies of single sided deafness are: Sudden hearing loss Acoustic neuroma otosclerosis Microtia

7.  What is the audiological criteria for single-sided deafness ≤45 BC dBHL in the non-implanted ear ≤45 AC dBHL in the non-implanted ear ≤20 BC dBHL in the non-implanted ear ≤20 AC dBHL in the non-implanted ear

8.  The Ponto bone anchored sound processor has Split and full directionality Adaptive directionality Automatic directionality All of the above

9.  The Feedback Manager in Ponto bone anchored processors Measures static feedback limits Uses static feedback cancellation Measures dynamic feedback Cancels feedback after it occurs

10.  The Speech Guard amplification system in Ponto sound processors is designed to Improve sound quality Reduce distortion Improve speech understanding in noise Handle sudden loud noises All of the above
