ORCA-USA is a hearing aid research facility located in the Illinois Technology & Research Corridor in the village of Lisle, Illinois (Suburb of Chicago). Founded in 2001, ORCA-USA along with its sister facility ORCA-Europe est. 2007, have been conducting clinical hearing aid research for their parent company WS Audiology.
WS Audiology designates considerable resources for audiological and technological research in the continual pursuit of refining and developing new hearing aid technology. The results of the hearing aid research conducted at this office assist us in our mission to develop high quality hearing instruments that give people with a hearing loss the same opportunities for communication as people with normal hearing.

The ORCA Repeat-Recall Test (RRT) is a speech-in-noise test that simultaneously provides an assessment of the patient's auditory working memory and reported listening effort. It measures 5 separate performances: repeat, recall, context use, listening effort and tolerable time. The test starts with the Repeat Task.
The Tracking of Noise Tolerance (TNT) test was designed to measure how much noise an individual can tolerate while still understanding 90% of speech. The test requires the patient to adjust noise levels while listening to a passage presented at a high level (75-85 dB SPL) for two minutes.
Our research shows that the higher the tolerable noise level (TNL), the more likely will the listener be satisfied with his/her hearing aids in real-life noisy situations.

The advanced features in today's hearing aids call upon the use of new tests to assess the effectiveness of those features. We developed a computerized nonsense syllable test to focus on high frequency speech sounds identification.
Hearing aid wearers fit with an open fit instrument, extended bandwidth or a processing algorithm such as frequency transposition may perform adequately on standard speech evaluation using conventional word lists and sentence tests.This poses a challenge to the clinician on how to demonstrate benefit for these types of fittings.

We are currently seeking adults with hearing loss and/or tinnitus to participate in upcoming studies. If you wear hearing aids, have thought about trying hearing aids, suspect you may have a hearing loss, or experience ringing or buzzing sounds in your ears, you may qualify to participate! All research studies are carried out in our research office in Lisle, IL in a relaxed, one-on-one setting.
