Question
What is involved in the Ponto 3 SuperPower management system?
Answer
The two components of the feedback system are phase inversion and frequency shifts. These two components work alongside feedback management, which is run during your fitting.
Dynamic Feedback Cancellation (DFC) System
If you want to provide high amplification, you need the feedback management system. Feedback results from vibrations from the skull feeding back into the instrument, which is patient dependent. The feedback manager defines the feedback margin or limits for the patient and is measured in the clinic. This allows for continuous gain control to avoid feedback.
Our dynamic feedback cancellation system works in everyday situations. DFC uses two steps:
- A phase inversion, which takes care of known feedback before it occurs
- Frequency shift, which breaks the feedback path
In cases of softband and headband users, the perceived loudness sound is weaker due to the skin and tissue attenuation as compared to abutment solutions. SuperPower will be better able to compensate for that loss in signal. In cases of single-sided deafness, we want to match the patient's better ear (which theoretically has a normal LDL and also a normal large dynamic range). We want to match their normal loudness perception in the better ear. The way to do that is to give them a large dynamic range with a SuperPower product. Patients with conductive and mixed hearing losses of all degrees can benefit from the larger dynamic range.
Ponto 3 SuperPower is not a niche product. It's mainstream. Soft sounds should be soft and loud sounds should be loud. We aim to preserve as much of the patient's dynamic range as possible. Ponto 3 is a single unit processor for power and quality and reliability. There's no need to wear an additional piece. It's all abutment level. It's discrete, small, and the battery lasts a long time.
