hearing aids for people with hearing loss

back to "New to Hearing Loss"

Hearing aids are one of the fundamental devices used by hard of hearing and late deafened people. They work by amplifying sound. There are many different types of hearing aids, each addressing particular needs. 

If you are interested in a general discussion one of the hearing aid types, please select the appropriate link below. If you would like information on a specific hearing aid, please see the Hearing Aid portion of our Resource Directory. 

Want to see what people think about the cost of hearing aids?

We believe EVERY hearing aid should include a telecoil. Here's more on this important technology.

Conduction Aids

Conduction aids work by sending the acoustic energy through the bones of the skull. These aids are effective for some types of hearing loss. The functioning of the Hisonic aid is typical of bone conduction aids.

Misonix Takes Step Forward in Ultrasonic Hearing Aid Market

October 2005

Editor: Several years ago we reported on the HiSonic hearing aid, which caused quite a stir at the time. It is an ultrasonic, bone conduction aid that the manufacturers said could assist people with sensorineural hearing loss who did not benefit from conventional hearing aids. It was even suggested as a potential alternative to Cochlear Implants. (See http://www.hearinglossweb.com/res/ha/hisonic.htm)

Then the company and product seemed to just disappear, until now. A company called Misonix has apparently bought Sonic Innovations (HiSonic developer) and is working to commercialize the HiSonic product.

Here are portions of the press release.

~~~~~~~~~~~~~~~~~~~

FARMINGDALE, N.Y., Oct. 19 /PRNewswire-FirstCall/ -- Misonix, Inc. (Nasdaq: MSON), a developer of ultrasonic medical device technology for the treatment of cancer and other healthcare purposes, today announced that it has contracted Ceres Biotechnology, LLC for services to assist in brining to market its ultrasonic medical devices for those with severe hearing impairment. These activities are an important element to Misonix's strategy for preparing for commercialization the products that had been in development by Hearing Innovations. As announced earlier this year and following its reorganization under Chapter 11, Hearing Innovations, a developmental company with patented HiSonic ultrasonic technology intended to alleviate profound deafness and tinnitus, became a wholly-owned subsidiary of Misonix.

Virginia-based Ceres Biotechnology has been contracted for an indefinite period expected to last approximately 18 months. Deliverables under the contract include professional consulting services for the development of technology, software programming, technical and product development engineering, selection of commercial partners, and the creation, testing and development of prototypes. As part of the contract, Ceres Biotechnology will conduct a clinical trail intended to prove efficacy. Ceres envisions the development of a multifunctional unit that will incorporate technologies addressing sensory processes essential for hearing and interpreting sound. The technology also will enable improved hearing by those less impaired, thus significantly expanding the addressable market.

Bone Conduction Research

 

September 2006

 

Dr. Manohar Bance has been looking for sweet spots in the human skull. What he finds could lead to a major technological breakthrough for people with certain hearing impairments and spinoffs that could change how you listen to your IPod or cellphone and even how soldiers communicate on the battlefield. Boosted by a $2.6-million grant from the Atlantic Canada Opportunities Agency’s Atlantic Innovation Fund, the team he leads has embarked on a five-year project to change the tools used to channel the vibrations of sound through the skull to nerves in the inner ear, allowing people to hear even if they lack critical parts of the ear.  Full Story

Baha Hearing System is Loud and Clear!

January 2007

Jan. 5 felt like Christmas to Grace Williams. She was sitting in an exam room at the ENT Clinic of Iowa in West Des Moines when her doctor handed her a tan box about the size of a postage stamp. It was a new hearing device that processes sound through a titanium fixture that had been implanted in the bones of her head . . . . She tried placing the processor into the fixture behind her ear. She fumbled a couple of times, and her physician, Dr. Tim Simplot, stepped forward to help. Suddenly, her hearing had a clarity she had never known.  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

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
