cv01.jpg (8206 bytes) SeboTek™ Hearing Systems, Tulsa, Okla, offers the PAC (post auricular canal) aid. The concept behind the patented design of the PAC is the separation of the sound processor and the speaker. This design enables the speaker to be free-floating with an active seal deep in the ear canal, resulting in reduced occlusion effect and feedback sensitivity. The PAC is a discreet instrument that fits mild to severe hearing losses, and offers same-day fittings and instant repairs. (800) 388-9041; www.SeboTek.com.
