BANG! Free Webinar addressing damage from impulse noise & the effectiveness of hearing protection


Some of the most hazardous sounds we hear are brief sounds – noises from impacts and impulses. These arise from sources like household tools, construction, industrial noise, firecrackers, guns, and even automotive airbags. The progression of damage to the ear from such impulse sounds differs from damage to the ear that progressively occurs as a result of long-term exposure to high-level noise. Beyond understanding the various mechanisms and related damage-risk criteria specifically associated with impulse noise, it is important for audiologists to recognize appropriate hearing protection recommendations for such noises, including understanding how hearing protection device efficacy is measured, how these products perform, and suggestions for use.

elliott_berger_300x300-150x150To gain insight on the topic, 3M is offering a free webinar presented by Elliot Berger, M.S. on Thursday, September 22, 2016 at 12:00 pm (CST). For nearly 40 years, Mr. Berger has studied hearing protection, hearing conservation, and related topics, and has presented his research in 14 textbook chapters and over 60 published articles. He chairs the ANSI working group on hearing protector attenuation and has served on a National Academy of Science committee evaluating hearing loss in the military. Log in, listen, and learn!

Hush™, the World’s First Smart Earplugs – guest blog post by Daniel Lee

snoringSnoring can be very disruptive to one’s sleep and has a much deeper negative impact than may be initially realized. Studies show that spouses lose more than an hour of sleep as a result of their snoring spouses. Also, the sleep they do manage to get is oftentimes so disrupted and fragmented, that a severe debilitating shortage of restful sleep results. There are many who may not even realize the extent that their sleep is disturbed by noise. According to the National Sleep Foundation, “Noise can jostle your slumber – causing you to wake, move, shift between stages of sleep, or experience a change in heart rate and blood pressure – so briefly that you don’t remember the next morning”.2 It’s so bad, that couples often resort to extreme measures. Almost a quarter of American couples end up sleeping in separate bedrooms in order to cope.3

tinnitusBeyond snoring, there are many other noises that can disrupt sleep including noisy neighbors or roommates, and unwanted sounds of the city. In addition, tinnitus is a condition that can be quite bothersome for many individuals particularly when trying to fall and/or stay asleep.  Audiologist are involved helping patients manage their tinnitus and now have a new, unique solution to offer some of their patients as a solution at night.

hush productHush is the world’s first smart earplugs designed to block out sound using the combination of two proven methods: 1) passive noise reduction, and 2) noise masking. Like earplugs, Hush’s foam insert earphones passively reduce outside noise up to 30 dB. In addition, the earphones wirelessly pair to any smartphone, providing the user with access to 15 soothing sound tracks that mask any residual unwanted noise. By synergistically combining an earplug with a sound machine, Hush offers your patients an elegant, economical, and effective means of blocking out unwanted noises to help facilitate a good night’s sleep.

hush-appKeep in mind, there are some things that a user will need to be able to hear while using Hush.  Through the use of the Hush app, key notifications will continue to be wirelessly communicated from the user’s smartphone to the smart earplugs. The user has complete control over which notifications will be active, including selecting what phone numbers or alarms will wake the user.  The added bonus is that these alarms will only sound in the user’s ears without waking anybody else.

Marketing aside, while Hush comes with a variety of tips (foam and silicone) that should find a good fit with most people, Hush will not be a perfect fit for everybody. Hush is intentionally designed to be an in-ear device that sits flush inside the concha cavum such that it is comfortable even for side sleepers, but this can vary based on unique ear shapes.

Here are two unique ear characteristics to watch out for that might compromise Hush’s comfort and practical usage for some:

  1. When an individual’s tragus severely obstructs entry to the ear canal, Hush will not be able to fit correctly. This is evident if somebody inserts Hush and the tragus is stretched significantly. Although a person might not initially report discomfort, if the tragus is stretched significantly, it will become uncomfortable over a few hours, making Hush not a viable option for those with tragus-obstructed ear canals.
  2. When an individual’s concha cavum is very shallow, Hush will not be able to sit as flush to the profile of the head as intended. If that individual is a side/stomach sleeper, the protruding Hush may become irritating over a few hours.

For more information on tip choices, see the Oaktree Products LEARN MORE document located on Hush product page on their website.

Hush values our audiologist partners highly and is completely dependent on their expertise for our mutual success.  Where the expertise of an audiologist comes into play is in being
able to identify when Hush would be a good option for a particular person. Our goal with founder imagewith Hush is to maximize the amount of user happiness which is made possible by ensuring Hush is prudently offered to those for whom it would be a good fit. Hush is available to audiologists at Oaktree Products. For product information, contact Oaktree Products at 800.347.1960 and ask for customer service, or email inquires to  Daniel Lee (pictured right)  is one of the founders of Hush, a San Diego based technology company dedicated to improving lives by helping people sleep better.

Free app turns smart phone into ALD for TV listening

tunityAs previously mentioned in a guest post submitted for my colleague Gyl Kasewurm’s blog (see Hearing industry: rose bush full of thorns or thorn bush full of roses?), the hearing industry has been undergoing a drastic change, bringing the independent private practice owner newer and more challenging competition. Even if you choose to ignore it, the Internet has made it both possible and easy to purchase hearing instruments and hearing-instrument-look-alikes.  Big box stores offer end-users hearing instruments at lower price points while PSAPs continue to ruffle some audiology feathers. The change is happening and technology is becoming more readily accessible to everyone’s fingertips.  For example, there now is a relatively new app that can turn your smart phone into a TV listening device at a press of a button without any additional accessories.

Tunity is a free app that allows anyone with an iPhone or Android to stream audio from a live TV, even when it is muted, directly to the smart phone. When you scan the TV of interest, the app quickly identifies the channel and then automatically streams live, synchronized audio to your smart phone.


So, if you (or your hearing instrument wearing patients) are in a loud bar during March Madness trying to watch your alma mater play amongst the other competing games, you can easily access the audio of your TV of choice and have it streamed directly to your smart phone via the Tunity app. Likewise, if you find yourself in a dorm room situation where you want to watch TV while your roommate needs to study, use the app to direct the audio to your headphones. It is applicable at home, at the airport, in waiting rooms, and any other situation where there is a TV that is hard to hear whether or not you are a hearing instrument wearer. The applications are endless and the app is very cool. As an avid sports fan and frequent traveler, I now personally use it to optimize my TV listening experiences. Check it out for yourself at and let your patients know how they too can optimize their TV-listening experiences with the free Tunity app.

How do PSAPs fit into the modern audiology practice? – guest post by Drew Dundas

Over the years I’ve had the pleasure of working with many patients with a common set of complaints. Let me set the scene for you. It’s a morning or an afternoon on a day that ends with ‘y’, and your new patient explains that they have noticed that they’re having increasing difficulty understanding in situations such as restaurants and meetings, when trying to understand a lecture, or that they’re engaged in a nightly battle with a loved one for the TV remote control. ‘Hmm, I think I may have heard that one before,’ you think to yourself and start the case history and diagnostics. Your test results are unremarkable, with a little bit of a high frequency shift, but no red flags or glaring loss of hearing sensitivity. After explaining the test results to the patient, you’re faced with a bit of a dilemma. The subjective impact of these situational listening difficulties often outstrips the objective severity of the hearing profile of the individual.

So, it’s decision time. Do you explain that many people experience these challenges, but that because there isn’t really a significant change in hearing sensitivity as of yet that hearing aids are not an ideal solution at this time, and suggest some listening strategies? Or, do you by default bring up the idea of amplification and assistive technologies like an FM setup?

soluton-wowDay in and day out, I found this to be a frustrating decision to make. We know that the right technology can help these patients and have a substantial positive effect on their overall quality of life, but hard won experience has shown us time and time again that it is a truly rare patient who is able to justify and afford thousands of dollars of technology to address difficulties that arise in only a few situations each day. The solution that has been needed is one that gives patients a speech intelligibility enhancement, maybe a little gain in the right frequency range, an improvement in signal to noise ratio that’s comparable to an FM, and a way to package it all so that the cost to the patient is easy to justify for those few hours a day where the technology is needed. Because it’s likely to be a low cost solution, it shouldn’t take up too much of the clinician’s time, so it should be easy to set up, adjust and use. Oh, and ideally, we don’t want the device to be visually confused with a hearing aid, because the devices have very different purposes. Until recently, there simply hasn’t been a solution that would fulfill these needs, so we were forced to suggest that the patient come back in a year or so for retest, and, well, how often does that really happen?

opportunity-fishOne of the worst things that can happen here for the patient (and the clinician) is to establish the idea that technology isn’t going to help, because once this idea is established, it’s very difficult to alter. It may also explain why many of the patients never return to our practices. Instead, if we can establish and demonstrate that technology can be helpful, we create a therapeutic relationship with the patient that will bring them back to the clinic if and when their difficulty worsens. What a great opportunity for patient and provider alike, especially when we consider that it typically takes years for people to seek assistance and adopt traditional technology after recognizing the existence of a significant problem.

economicsHere’s where PSAPs come into the picture, and equally importantly, into the economics of the dispensing practice. Marketing wisdom suggests that it costs between 5 and 25 times more to capture a new customer than it does to retain an existing one.[1] Further, hearing industry data suggests that once a patient has purchased a solution from a hearing healthcare professional, that there is a 95% probability that they will purchase their next device from that same practice. Third, once technology is adopted, the average product lifecycle is less than five years.[2] Contrast this with the average time to adoption of hearing aids after identification of hearing impairment, at greater than 9 years. From a purely financial perspective, it makes sense to the professional to offer PSAP solutions, as this provides an opportunity to build a relationship with a patient, makes the patient more likely to return to the practice, and opens the door for earlier adoption of hearing aids when audiometrically appropriate. Of course, there’s an extensive set of much more important reasons to offer these technologies to patients who are not yet ideal hearing aid candidates, that fit under the umbrella of improving quality of life.

Evidence suggests that individuals with untreated even mild hearing impairments experience an increased incidence and severity of depression relative to normal hearing deprivationpeers AND those who make use of hearing technologies.[3] They are also more likely to experience fatigue, irritability, anxiety and social isolation.[4] Most recently, researchers have identified a link between untreated hearing impairments and cognitive decline. [5]These problems help to create a compelling argument in favor of adopting assistive listening technologies sooner, rather than later.

PSAP products can provide a ‘gateway’ solution for individuals who are not yet ideal hearing aid candidates. Some products are designed to emphasize signal to noise ratio enhancement, providing many of the features found in high end hearing aid devices in addition to wireless remote microphone technology. Most are intended for situational use only, instead of all day wear. A new generation of these devices has introduced designs that don’t look like hearing aids from the 1970s, and simultaneously provide additional connectivity and great flexibility for the user. Most importantly, they are not visually confused with hearing aids, making it easier for the professional to make the differences in intended use between PSAPs and hearing aids clear to the patient.

mobileWe are now experiencing the first significant step forward in hearing technology since the introduction of digital signal processing. The confluence of mobile computing power, increased connectivity and enhanced communication is combining with commercially available audio processing solutions and hearing science to create a new marketplace, rather than cannibalizing from existing sales. Hearing healthcare professionals now have the opportunity to establish the appropriate time and place for PSAP technology in the hearing journey of the patient. Incorporating these products into your practice helps to maintain the professional’s position of authority relative to hearing healthcare, and furthers the aim of every professional, namely to provide the best solution for the patient and to become a partner in hearing health, for life.

OutreachThe long and short of it is that PSAPs are not a threat to Audiology, or a hearing aid alternative, but rather, they are simply another tool in the box of options, an opportunity to build relationships with new clients, a chance to consider more than a ‘hearing aid or nothing’ and maintain credibility with the patient by providing more than a single approach to dealing with listening difficulties. Most importantly, considering PSAP products for the right patients is another way to serve the highly varied needs of our rapidly expanding patient base. The next time you encounter a patient who isn’t yet a great candidate for full-time amplification but who still reports a lifestyle impact due to situational listening difficulties, why not consider a PSAP product? You just might be surprised.

What was HOT in Phoenix at AudiologyNow2016: Top Five Breakdown

booth535AudiologyNow2016 has come and gone. If you were unable to attend or made the trip to Phoenix but need a little reminder as to what was hot, have no fear! The Oaktree Products’ team (pictured right) included Nicole Borg (customer service), Dr. A.U. Bankaitis, PhD (audiologists and VP), Maggie Kleffner (Purchasing), Dave Kemp (Marketing), Dana Drady (Marketing) and Michael Kemp (General Manager); this group made mental notes regarding products generating the most interest, questions, and/or “Wow!” response amongst attendees at this year’s convention.  Here is a quick run-down of the five hottest items at the Oaktree Products booth (#535):

  1. Otoscopes were the most popular item of interest, in particular the Firefly DE-550 wireless video otoscope, the new and colorful Welch Allyn PocketPlus LED pocket otoscopes, the Heine Mini-3000 fiber-optic, and renewed interest of the Horus+ video otoscope
  2. New PockeTalker 2.0 generated buzz not only because of its sleek and ergonomic design, but mainly because of the added t-coil option. Juliette Sterkens actually shed a few tears while holding it in her hands. How does it compare to previous PockeTalker models? Check out this PockeTalker Summary making sure you scroll down to see the comparison chart for a quick visual breakdown.
  3. The ThinkLabs-One has been around for a couple of years and the crowd in Phoenix had a lot of great questions about it and amplified stethoscopes in general. If you want to learn more, check out Oaktree Products’ amplified stethoscope section and A.U. Bankaitis’ Audiology Blog’s amplified stethoscope section.
  4. The loupes on display for cerumen management and other audiology applications including the FS600, Seiler LED, and MegaSpot 6000 seemed to never rest on the mannequin heads and were constantly worn by audiologists visiting the booth. Guess what? In addition, the cracker-jack Oaktree Products team learned about another loupe that we will soon offer….it is so awesome that it deserves its own future blog post
  5. Believe it or not, a lot of audiologists were proactively seeking PSAP and hearable solutions for potential patients and the SoundHawk and Bean were a big hit.

While many other items were on display that generated a lot of interest (i.e. totally affordable Econ LED Ear Light, stainless steel wax loops), limiting selection to the top five was difficult but pretty much reflects what audiologists were most interested in checking out. For more information, surf the Oaktree Products website (it’s free) or contact anyone at Oaktree Products toll free 800.347.1960 or via email at  By the way, we are all over social media so follow us on and contact us via Facebook, Twitter, and Instagram.  See you in Indianapolis in 2017!
