In February 2013 the Company filed a clinical study protocol entitled "A Comparison of the HyperSound Audio System to Conventional Audio Speakers in Patients with Mild to Severe Hearing Loss" with an independent review board and received clearance to commence the study in late March 2013. The study was designed to assess whether the Company's HyperSound audio improves sound clarity when compared to a conventional acoustic speaker in those persons with mild to severe hearing loss.
The Company engaged the California Hearing & Balance Center of La Jolla, California under the guidance of principal investigator, Dr. Ritvik Mehta, to conduct patient studies that commenced in April 2013.
"We are pleased to report that preliminary results from this scientific study confirm the outcomes from previously announced preference testing," reported Kenneth F. Potashner, executive chairman of Parametric Sound. "We consistently witness that more than 70% of persons with hearing loss prefer the clarity of HyperSound and many people are reporting dramatic improvement in hearing and clarity. We will report final results when the study is complete. We expect that HyperSound can enable products that can enhance the audio enjoyment of a broad segment of the aging and hearing impaired population."
According to a study in a November 2011 issue of Archives of Internal Medicine,hearing loss affects nearly 48 million Americans. For individuals 12 years and older in the United States, nearly 1 in 8 has bilateral hearing loss, and nearly 1 in 5 has a unilateral or bilateral hearing loss severe enough to interfere with day-to-day communication. The study further states that the prevalence of hearing loss is expected to rise because of the aging of the population. The Company believes one of the major issues experienced by the hearing impaired is lack of clarity in differentiating words from each other even with loud volume. The Company also believes its emitters may provide benefits in this area by delivering with clarity the frequencies important in speech recognition, thus improving the TV viewing experience by those with normal hearing, and by providing amplification for those with some hearing loss without the need for headphones or any coupling to the ear or body.
The Company also reported that it has hired Brian Kappus, Ph.D., as a senior research scientist with responsibility to focus scientific study and research on hearing and other novel applications of HyperSound technology. Dr. Kappus has more than twelve years experience in experimental and theoretical physics and pioneered new techniques in acoustical and light measurement. While recently working at UCLA he joins the Company with a thorough understanding of HyperSound technology and acoustics.
