Flashcards in AB vs. Cochlear and Med-El Deck (21):
1

Differences between companies:

Temporal Resolution

(stimulation rate, pulses per second (pps))

AB HiRes BES: Up to 83,000 pps
COH's Nucelus Freedom System: Up to 32,000 pps
COH's Nucleus 5 System: Up to 31,500 pps
Med-El's Maestro System: Up to 50,000 pps

2

Differences between companies:

Why Temporal Resolution Matters

The faster the stimulation rate, the more accurate the timing of sound.

3

Differences between companies:

Spectral Resolution

(spectral bands)

AB HiRes BES: Up to 120
COH's Nucelus Freedom System: Up to 22
COH's Nucleus 5 System: Up to 22
Med-El's Maestro System: Up to 12

4

Difference between companies:

Why Spectral Resolution Matters

The higher the resolution, the more detailed and richer sound you hear.

5

Differences between companies:

Potential Pitch Percepts

AB HiRes BES: 460*
COH's Nucelus Freedom System: 161*
COH's Nucleus 5 System: 161*
Med-El's Maestro System: Data not available

6

Differences between companies:

Why Potential Pitch Percepts Matter

The more pitch percepts, the better the opportunity you have to differentiate complex sounds like music.

7

Differences between companies:

IDR

(input dynamic range; dB)

AB HiRes BES: up to 80 dB
COH's Nucelus Freedom System: 45 dB
COH's Nucleus 5 System: 45 dB
Med-El's Maestro System: 55 dB

8

Differences between companies:

Why IDR matters

The wider the range, the larger spectrum of sounds you hear.

With narrow IDR, soft sounds are cut out and loud sounds are compressed, creating disproportionate relationship of inputs within environment.

(normal hearing ear has wide dynamic range ~100 dB)

9

Differences between companies:

Current Sources

AB HiRes BES: 16
COH's Nucelus Freedom System: 1
COH's Nucleus 5 System: 1
Med-El's Maestro System: 4

Med-El has 12, but haven't implemented a strategy using simultaneous current steering

10

Differences between companies:

Why Current Sources matter

Multiple current sources allow unique sound processing strategies

11

Differences between companies:

Stimulation Phase Inversion

AB HiRes BES: Yes
COH's Nucelus Freedom System: No
COH's Nucleus 5 System: No
Med-El's Maestro System: No

12

Differences between companies:

Why Stimulation Phase Inversion Matters

Stimulation phase inversion allows unique stimulation patterns intended to provide improved tonal clarity

13

Differences between companies:

Sound Coding Strategies

AB HiRes BES: ClearVoice, HiRes 120-S, HiRes 120-P, HiRes-S, HiRes-P, CIS, MPS
COH's Nucelus Freedom System: ACE, CIS, SPEAK
COH's Nucleus 5 System: ACE
Med-El's Maestro System: FSP, HP-CIS

14

Differences between companies:

Why sound coding strategies matter

Every ear is different, so the more sound strategies offered, the more options you have for hearing your best.

15

Differences between companies:

Natural Mic Placement

AB HiRes BES: Yes
COH's Nucelus Freedom System: No
COH's Nucleus 5 System: No
Med-El's Maestro System: No

16

Differences Between companies:

Why Natural Mic Placement matters

With AB's T-Mic, connect to audio devices like normal-hearing people do; enjoy natural, focused listening.

17

Differences between companies:

Case Impact Resistance

AB HiRes BES: Up to 6 joules
COH's Nucelus Freedom System: Up to 1 joule
COH's Nucleus 5 System: Up to 2.5 joules
Med-El's Maestro System: data not available

18

Differences between companies:

Why Case Impact Resistance matters

The more joules your CI can resist, the more impact it can take without affecting performance. From flying soccer balls to falling off a bike, you can have peace of mind knowing that AB implants are Built Kid Tough.

19

Differences between companies:

Swimmable Technology

AB HiRes BES: Yes
COH's Nucelus Freedom System: No
COH's Nucleus 5 System: No
Med-El's Maestro System: No

20

Differences between companies:

Why Swimmable Technology matters

Only AB offers Neptune, the world's first and only waterproof, swimmable sound processor.

21

Med-El's main objective

convince industry that deep electrode insertion provides low frequency emphasis that can be beneficial for music and tonal languages
