Comparison of two different bone anchored hearing instruments.

Purpose: To compare the audiological performances of Turkey's most up-to-date bone conduction implant processors.

Methods: Twenty-six bone-anchored hearing instrument users, thirteen in each group, were evaluated for speech understanding in quiet and several signal-to-noise ratios.

Results: We noticed the differences at 0.5 and 1 kHz measurements in free field frequency specific test, aided SRT scores, non-adaptive and adaptive matrix test results for a few conditions created a statistically significant difference in favor of Baha-6.

Conclusions: Both processors offer positive gains to their users in noisy and silent conditions. However, the data showed statistically significant differences for some measurements that may be critical for patients in daily practice.
