Siemens Triano Press Release

PISCATAWAY, N.J., July 30, 2003 - Siemens Hearing Instruments announced today that over 95 percent of the individuals with hearing loss tested in the company's TRIANO™ hearing instrument clinical trials, understood speech in noisy situations within the range of normal hearing individuals ages 18 - 29 years old. The research, conducted at the University of Iowa and University of Pittsburgh, used the HINT (Hearing In Noise Test) to examine speech understanding in challenging, noisy environments.
Thomas Powers, Ph.D., Siemens director of Audiology and Strategic Development said, "This is extremely encouraging news for the millions of people suffering from hearing loss who have problems understanding speech in difficult listening environments. In fact, when using TRIANO hearing instruments, older individuals with significant hearing loss understood speech in environments with background noise as well as younger college students with normal hearing."

"Before the final analysis of our clinical trial results, we did not anticipate the magnitude of the improvement TRIANO could provide. Prior studies within the hearing aid industry have compared advanced digital products to less advanced products, which is like comparing a typewriter to a desktop computer," said William Lankenau, CEO and president of Siemens Hearing Instruments. "Our research compared the performance of individuals wearing TRIANO to individuals with normal hearing in the same demanding listening environment. This result will help prove just how beneficial wearing hearing instruments can be."

In the TRIANO research conducted at university sites, the participants were surrounded by noise, creating a very difficult listening situation. The participants tested were required to repeat sentences heard in the presence of competing multi-talker background noise. The background noise was specifically selected to be similar to the noise heard in restaurants and at loud parties.

At both of the University research sites, normal hearing college students (age range 18 to 29 years old) were tested to establish a "gold standard" for performance on the HINT. These results were then compared to results from study participants consisting of a large sample of older adults (average age of 62 years old) with mild-to-moderate sensorineural hearing loss.

When the "speech-in-noise understanding" score for the two different groups was averaged, statistical analysis revealed that the older individuals with hearing loss, wearing the Siemens TRIANO hearing instruments performed as well as the younger college students with normal hearing. Moreover, not only were average values similar, but 95 percent of the hearing impaired older individuals performed within the range of normal. The TRIANO hearing instruments with adaptive and automatic directional microphone system are available using either TwinMic™ or TriMic™ (only available on the TRIANO 3 BTE). The individuals with hearing loss were tested using both designs. The performance was somewhat higher for TriMic, but even with TwinMic the "speech-in-noise understanding" performance equaled that of the younger listeners.
