The efficacy of hearing aids in achieving compensation equity in the workplace

October 2010

There is an extensive body of research concerning the impact of hearing loss on quality of life.2,3 When we talk of quality of life, the benefits of healthy hearing are not limited to enhancing the esthetic pleasure of acoustic sounds in a person’s environment. Indeed, hearing loss has been shown to have a negative effect on nearly every dimension of the human experience, including: physical health, emotional and mental health, perceptions of mental acuity, social skills, family relationships, and self-esteem, not to mention work and school performance. In a review of the literature,4 Bridget Shield, PhD, a professor of acoustics at London South Bank University, has shown that hearing loss is related to unemployment and underemployment. However, research in this area has focused primarily on people with severe to profound hearing loss. The literature has historically been less clear regarding the impact of the full spectrum of hearing loss and how it impacts effectiveness in the workforce. In a 2005 Better Hearing Institute (BHI) study of more than 40,000 households, hearing loss was shown to reduce average household income by up to $23,000 a year depending on the degree of hearing loss.5However, the use of hearing aids was shown to mitigate the effects of hearing loss by 50%. The BHI estimated that people with hearing loss in the workforce could be losing more than $100 billion a year in income. This reduction in earnings not only damages the quality of life of the person with hearing loss, but it also has a detrimental impact on society as a whole due to reduced productivity and losses in tax revenues.  Full Story


New Device Prevents Hearing Aid Loss

July 2010

To prevent the loss of your hearing aids, just loop the connector onto your hearing aids and your eyeglasses it is just that simple. The 6 dollar Loopum connector is cheaper than buying hearing aid insurance.  If you do not want to pay at least $650.00 for a replacement hearing aid, then read MY STORY.  Since hearing aids can be misplaced or lost so easily, the Loopum connector prevents lost hearing aid from occurring.  The clear plastic connector is invisible since it is located behind the ear.  The Loopumconnectors are an ideal hearing aid safety solution for children or adults wearing the BTE hearing aids.  It is also ideally suited for the elderly in Nursing Homes or patents having memory loss from Alzheimer’s disease.  More Information


Audiology and Baha: Good… Good… Good Vibrations!

May 2010

Today, when it comes to bone-conduction hearing aids, one product stands apart from all the rest-the bone-anchored hearing aid, or BAHA, which has become Baha, an osseointegrated cochlear stimulator. For some audiologists, working with Baha patients has become routine, and one such audiologist is our Page Ten guest author this month, William Dickinson, AuD. Dr. Dickinson is an assistant professor at Vanderbilt University and the coordinator of the Hearing Technologies program at the Vanderbilt Bill Wilkerson Center. In addition to his teaching and management roles at Vanderbilt, he is clinically active seeing patients, training AuD students, and working with applied research projects.   Full Story

Woman Eats Her Hearing Aid!

October 2009

“As I enjoyed the chocolate and caramel taste, it appeared that one of my Milk Duds was not as fresh as the others. One was rather crunchy and I could not get it to soften up, no matter how hard I tried.” The transplanted Texan was puzzled. Finally, she removed the dud Dud from her mouth. She wanted to see what the problem was. “I found out.” Apparently, as she had shifted into position on the bed, a hearing aid had fallen out of her ear and dropped right into the little box of candies. She couldn’t have done that on purpose if she had tried. The hearing aid was now coated with chocolaty goodness.  Full Story


Cochlear(tm) Baha(r) BP100 and Current Issues in Bone Anchored Hearing Technology

October 2009

The traditional indications for a bone anchored device like the Baha are similar to those for patients who would benefit from a traditional hearing aid or a traditional bone conduction transducer. The difference with Baha is that the patient has a condition that makes him or her unable to use a conventional device. The possible conditions include: patients with chronic ear infections, atresia of the ear canal, a patient who developed otitis externa with the use of traditional earmolds, and even patients who have nasopharyngeal carcinomas that require extensive radiation which lowers the patient’s tolerance of an earmold within the ear canal. These patients traditionally have a conductive or mixed hearing loss, with bone conduction thresholds no greater than 35 to 45 dB HL and speech discrimination scores of 60% or better.  Full Story


Australian Receives Cochlear’s BP100 Bone Anchored Hearing Aid

August 2009

On Friday Mr Hughes had tiny titanium screws drilled into bone behind each ear during a 90-minute operation under general anaesthetic. Once the wounds heal and the screws have fused with bone, abutments will be screwed into the implants, and the processors, about the size of a postage stamp, are clicked into place. Older-style hearing aids amplify all sounds, making it almost impossible for wearers to hear conversations in noisy environments. They also interfere with frequencies used by mobile and fixed phones and often emit high-pitched whistling sounds. But the newer processors, costing about $6000 each, shut out background noise, giving users up to 25 per cent better hearing, and can be attached directly to MP3 music players or wireless headsets for talking on the phone, Cochlear’s territory manager, Katrina Martin, said. They were useful for people with congenitally blocked middle ears, chronic infections that had eaten away tiny bones in the middle ear used for sound conduction, or babies born with closed ear canals, she said. Full Story


Bone Anchored Hearing Aids Work When Others Don’t

May 2008

Bone-anchored hearing aids (BAHAs) have been used in the United States since receiving Food and Drug Administration (FDA) approval in l996. BAHA is a registered trademark of Entific Medical Systems, a Swedish manufacturing company owned by Cochlear Limited. The bone-anchored aid is a surgically implantable system that works through direct bone stimulation.  According to the Maryland Hearing and Balance Center, “The baha consists of three parts: a titanium implant, an external abutment, and a sound processor. The system works by enhancing natural bone transmission as a pathway for sound to travel to the inner ear, bypassing the external auditory canal and the middle ear. The titanium implant is placed during a short surgical procedure and over time naturally integrates with the skull bone. For hearing, the sound processor transmits sound vibrations through the external abutment to the titanium implant. The vibrating implant sets up vibrations with the skull and inner ear that finally stimulate the nerve fibers of the inner ear, allowing hearing.”  Full Story


To CROS, or not to CROS?

April 2008

Profound sensorineural hearing loss in one ear only, sometimes called single-sided deafness, has numerous causes, including idiopathic sudden hearing loss and the removal of an acoustic tumor. Although single-sided deafness has generally been considered a minor inconvenience when compared to hearing loss in both ears, the ability to hear in one ear only presents a number of listening disadvantages. First, when the speaker is on the side of the non-hearing ear, the amplitude of high-frequency sounds critical for speech perception and understanding is reduced by as much as 20 dB SPL as they travel through and around the head to reach the hearing ear. This obstruction of sounds by the head, called the head-shadow effect, can also impair sound localization and distance estimation.  Second, the loss of hearing in one ear prevents the perceived doubling of loudness normally experienced through the binaural summation of sound energy coming into the two ears simultaneously.  Third, the ability to squelch background noises in favor of foreground speech is lost or diminished, making listening in noise especially difficult.   Full Story
