National Audiology Awareness Month: More than 30 million Veterans experience hearing loss
Posted on October 13, 2016

Hearing loss, including tinnitus, which is a ringing, buzzing or other type of noise that originates in the head, is the most prevalent service-connected disability among Veterans, with more than 30 million Veterans suffering from a form of it due to frequent exposure to loud noises from weaponry and aircraft. Because of the pervasiveness of hearing loss among Veterans, VA is recognizing October as Audiology Awareness Month by highlighting important VA research on the subject and advances made in treating Veterans with hearing loss.

“VA researchers have a rich history of contributions to audiology,” said VA Under Secretary for Health Dr. David J. Shulkin. “From working with the National Institutes of Health to develop and evaluate hearing aids to a comprehensive protocol for managing tinnitus at VA and other audiology clinics nationwide, VA is proud to be a leader in this field.”

VA researchers conduct a wide range of studies in audiology—from biomedical investigations to large clinical trials and epidemiologic database studies. Much of the work takes place at VA’s National Center for Rehabilitative Auditory Research in Portland, Oregon, one of the world’s leading facilities for research in the field. Studies include older Veterans whose hearing problems have been compounded by aging and younger Veterans who may have suffered hearing loss as a result of blasts in Iraq or Afghanistan.

Recent VA research includes the following:

  • In 2013, researchers at the VA Puget Sound Health Care System published the results of a study comparing group and individual visits for hearing aid fittings and follow up. The team found no differences in how well the hearing aids performed, or how often they were worn. They concluded that group visits could reduce costs while providing community support for patients.
  • In 2014, VA researchers in Loma Linda, California, linked exposure to jet propulsion fuel with auditory processing problems—changes that occur inside the brain rather than the ear.
  • A 2015 VA study yielded promising results on transcranial magnetic stimulation as a tinnitus treatment. The therapy involves holding a magnetic coil to the head. The team now hopes to conduct a larger trial.
  • A 2016 study of nearly 200 Veterans with tinnitus explored the impact of Post-Traumatic Stress Disorder (PTSD) on how Veterans manage the hearing condition, and offered guidance for clinicians.

Below are a few examples of ongoing studies:

  • VA researchers in Pittsburgh, Sioux Falls, Omaha, and Portland are collecting data from nearly 470 Veterans to learn more about auditory complaints in those who have been exposed to blasts. The team will focus on the interplay among hearing problems, traumatic brain injury, and PTSD.
  • A VA trial aims to improve monitoring of hearing changes caused by the drug cisplatin, used to treat cancer. Some 4,000 Veterans receive the drug in a typical year, and up to 40 or 50 percent will experience some hearing loss or tinnitus. The researchers say early detection can prevent significant damage.
  • Together with a lab group at the Massachusetts Eye and Ear Infirmary, VA researchers are seeking biomarkers—including cellular changes— that could warn of impending hearing loss. The work is expected lead to new preventive measures or treatment.

In addition to VA’s audiology research work, the department announced last month – ahead of National Audiology Awareness Month – that Veterans who need routine audiology appointments will be able to directly schedule them, without the need for a referral from their primary care provider. The move is expected to get Veterans into appointments more quickly. The new expedited process was piloted at three VA sites last year and is now being rolled out nationwide.
