3-D Scanner Maps Ear Canal to Improve Hearing Aid Development

By Stephanie Baum, MedCityNews.com 3/30/2013

In a move to disrupt the hearing industry, a medical device company has launched a a hand held 3-D scanner to map the inner ear to improve the quality of hearing aids. It’s also offering the platform to any hearing aid maker that wants it.

The medical device company received a green light for its 3-D Ear Canal Scanner from the US Food and Drug Administration earlier this month.

Boston-based Lantos Techologies’ 3-D Ear Scanning System is designed to be a more efficient way to scan the “ear toplogy” than the current approach, which involves the uncomfortable process of making a silicone impression to develop customized ear devices. Lantos’ technique involves a scanner with a membrane and video otoscope at the end. The membrane fills with fluid to conform to the ear canal. The video otoscope captures images and generates a 3-D scan of the ear in a process that takes under one minute, according to a company statement. Taking these measurements is key because,like fingerprints, each person’s ear canal is different.

CEO Jeff Leathe said as part of the process for developing the hand held 3-D ear canal scanner, they needed to create a video otoscope that could conform to their needs so the company will also be selling it to the audio industry.

In an interview with Technology Today, Leathe said: “Our goal is to replace the medieval art of impression taking. Everyone knows on a global basis that impressions are inconsistent and they don’t go deep enough.” He added that the scanner creates more real estate in the ear canal to the benefit of audiologists, ear bud developers and the security industry.

As hearing aids have become smaller and “invisible” they need to be positioned deeper inside the ear canal.

The device was developed at an MIT research laboratory and is expected to expand the options for hearing aids and lead to advances in earphone acoustic technology. Among the company’s investors are Catalyst Health Ventures, Excel Venture Management, Omega Funds and Mass Medical Angels.

HLAA Workshop: Sounds for Seniors: an Honest Look at Hearing Loss in the 55+ Community

July 8, 2011 in Education & Outreach

 By Bonnie O’Leary  7/7/11

I chose this workshop because I have spent so many years providing outreach to the senior community here in Northern Virginia.  Sheila Adams of DeLand, Florida, gave a very interesting program with a personal touch to it.

Ms. Adams lost her hearing when she was a  young adult, getting her first hearing aid at the age of 27.  At 47, she received her first cochlear implant, and she got her second implant at the age of 55.    Her career as a school teacher was filled with struggles caused by her hearing loss, and she talked about overcoming  those challenges.

Ms. Adams spent some time talking about her own family whom she feels represents senior citizens in many ways.  Her mother has been hard of hearing all her life, but very active because she has worn hearing aids and used assistive listening devices.  She has been married to Ms. Adams’ father for 63 years, but he now has Parkinson’s disease which causes him to speak softly and makes it harder now for her mother to communicate with her father.   Both have a slight memory loss.  One of Ms. Adams’ aunts is 88, and can still hear.  Another aunt is 90 and has glaucoma as well as macular degeneration.  Just observing these and other aging family members, Ms. Adams sees a wide range of senior issues that impact socialization and communication.

Seniors were categorized as “young-old” (ages 55-75) and “old-old” (ages 75+) as Ms. Adams discussed successful aging.  Successful aging depends on how well seniors accept change and loss.  These can include physical, psychological, social, economic, and interpersonal.  A lot will depend on the senior’s endurance and attitude as well as manual dexterity.    An “old” senior, for instance, can’t go back to normal after bad sprains or broken bones.  Those sprains become the new normal, and they have to accept that they need help, which is not easy for seniors who have been active and independent throughout their lives.  Adapting to  hearing loss is also difficult, especially when the senior has had a lot of other issues to contend with, whether they be physical or emotional, such as grieving over the death of friends.  Sometimes, Ms. Adams has found in her own family that “one’s perception of health is a greater influencing factor than one’s actual health.” 

How aging impacts hearing

The accumulation of noise over the years eventually takes its toll in the inner ear, causing age-related hearing loss.  But there are other physical changes happening at the same time.  There is often more and harder wax that accumulates and is increasingly difficult to remove.  The ear canal narrows, and the sensitivity of the hair cells changes, often producing a greater sensitivity to noise.  With these changes, there is a slowing of the message-carrying ability of the ear which can produce changes in perception.  Cognitive changes include a shortened attention span as well as fatigue.

Quality of life

Staying connected is a huge party of successful aging, maintaining the relationships that are important to seniors.  Having something meaningful to do, a purposeful activity, is also important, as well as have opportunities for intellectual growth and learning.  Recreation and entertainment are a part of staying connected, and Ms. Adams remarked how ironic it is to have more time in retirement but also more limitations in our abilities to do things.  Finally, a senior’s quality of life is also enhanced by spiritual growth and as well as a sense of hope, of having some positive prospects.  Hearing loss can render all of these desired aspects of life very challenging.

Factors affecting how a senior handles hearing loss

The temperament and personality of a senior will play a large part in determining how well he or she handles hearing loss.  Someone who is passive and has never had a lot of self-confidence is likely to become more quickly withdrawn than someone who is an assertive, or even aggressive, type of individual.  The perception of need is also important, accepting that it’s okay to get help, that hearing loss does not make him weak or “less than”.  But some seniors are content with their situations, their connections, and therefore are in no hurry to get hearing aids or undertake any other self-help types of activities to compensate for their hearing loss.  It is important for seniors to understand the impact that their hearing loss has on others as well, on their families and friends who can feel very frustrated when trying to communicate too.  A senior’s “knowledge base” is another factor that contributes to how he or she will handle a hearing loss.  There is a lot of misinformation about hearing aids and cochlear implants which could shape a  senior’s attitude towards getting help.  An understanding of options is important, and whether or not there are resources within their communities.

Solutions

There are 4 A’s to consider:  Amplification, Advocacy, Assistive listening devices, and Alternatives.  Seniors need to know the sources for financial assistance for hearing aids if they need it, and audiologists need to be more vigilant and honest in the way they fit seniors for hearing aids.  Seniors should also be kept up to date on hearing resources available in theatres and  movies, how to use captioning on television, how to develop better communication strategies with their families and friends.

Hearing Aids

Hearing Aids: What You Should Know Before You Buy!

  1. See your doctor first unless you have had a physical within the last 6 months. Some hearing aid specialists will ask you to sign a medical waiver in order to speed up the process of hearing aid sales.  This is not in your best interest.
  2. Check out the business selling hearing aids by contacting your local Better Business Bureau, consumer protection agency, or state attorney general.
  3. Know the difference between Audiologists and hearing aid dealers! Today, Audiologists require an Au.D., Doctor of Audiology, to certify. (This is NOT an M.D., however!).  Most have at least a Masters in Audiology, and they provide diagnostic audiological services.  They also have training in areas such as  listening/communication strategies and the perception of sound.  Hearing aid dealers become experts in hearing aid technology through numerous courses and apprenticeships with other hearing aid dealers.  Both are in the business of selling hearing aids.  What matters most is that the professional you choose is knowledgeable, ethical and provides a patient-driven service rather than a sales-driven service.
  4. Take someone with you when you go for your hearing aid evaluation who will take notes for you.  The results of the hearing test and the options for hearing aids can be confusing.
  5. Beware of ‘the deal’! If the Audiologist or dealer  tries to pressure you with promises like  ‘10% discount’, ‘$1,000 off’, ‘a lifetime of free follow-up visits’, ‘a lifetime of free batteries’, etc., this is a good indication that he or she is sales-driven.  Many are under contract to sell a certain number of hearing aids a year, putting their own interests ahead of yours.
  6. Take advantage of the 30 day trial period. In Virginia, you can return the hearing aids at the end of that time if you are not happy with them.
  7. Ask about fees for returning the aids. Each dispenser has his or her own business policies regarding the fee for returning them – it can be anywhere from 4% to 20% of the cost of the hearing aid.
  8. Please remember:
    • Hearing aids do NOT stop hearing loss.
    • Hearing aids will NOT restore your hearing to normal.
    • ALL Audiologists and dealers will provide free hearing aid adjustments during the trial period.
    • There is NO BEST HEARING AID because everyone’s hearing loss is different; what works for one person might not work for someone else.
    • You own your audiogram, be sure your specialist gives it to you.
    • A hearing aid should fit comfortably and not whistle.
    • No hearing aid cuts out background noise, but it can be made more tolerable.
  9. Ask about the telecoil – is it appropriate for your hearing loss. The telecoil is a small magnetic coil inside the hearing aid that bypasses background noise when you are using the telephone or an assistive listening device.  It is a very valuable feature and you can activate it with the push of a button.
