Towson takes lead in international hearing aid study

New device shows potential to motivate those reluctant to wear hearing aids

TOWSON, Md. (Sept. 26, 2011)—Towson University was the lead research team investigating the efficacy of a new hearing aid manufactured by the Danish company Oticon.

In the United States, hearing aids are considered medical devices, and the U.S. Food and Drug Administration requires hearing aid companies to obtain independent research to verify product claims. Dr. Brian Kreisman, associate professor in TU’s Department of Audiology, Speech-Language Pathology and Deaf Studies, was the primary investigator on the project and coordinated the efforts of Oticon executives and researchers from Hörzentrum in Oldenburg, Germany.

Joining the Towson research team were Drs. Jennifer Smart and Stephanie Nagle, who collected data. Dr. Candace Robinson conducted hearing aid fittings and verification, and doctoral research assistants Caitlin Marczewski and Cortney Butler also assisted in the study.

Results of the study with first-time hearing aid users suggest that Oticon’s new hearing aid, the Intiga, provided users with immediate and obvious benefits. The study also showed that, while typically it takes new users a longer time to accept amplification, the participants in the international study immediately accepted the new Intiga.

Study participants reported positive experiences in a variety of key performance areas including comfort in ear, comfort with loud sounds, one-on-one conversation in quiet and speech in noise. The majority of participants indicated a determination to wear their new hearing instruments long term.

The Intiga hearing aid is suitable for people with mild to moderate hearing loss. Those interested in learning more about the device should contact the Towson University Speech, Language and Hearing Center at 410-703-3095 or
