Market acceptance of thin-tube devices, and their ability to provide patients with a cosmetically appealing same-session fitting that is free from the occlusion effect (OE) has been tremendous. For those with a moderate or severe hearing loss, the SeboTek PAC is the only thin-tube option available—making it an essential offering for today’s hearing care professionals.

The SeboTek PAC offers a unique coupling system that can fit nearly any loss—up to 90 dB without occlusion effect or feedback. Clinically proven to eliminate occlusion effect (Figure 1), the SeboTek PAC uses the most effective method of doing so—a minimal-contact acoustic seal (Figure 2). This acoustic seal also overcomes the many challenges and limitations that occur with open canals, including feedback, group processing delays, ambient noise interference, and decreased directional microphone performance.

Microphone/speaker separation—far greater in distance than with other hearing aids— is also a key component. The PAC’s patented design, with its unique coupling system and Ultra Soft Tip, is able to accommodate jaw motion, which could create a slit leak in other hearing aids, another possible cause for feedback.
