Air Travel and Ear Pain

With the summer holiday season fast approaching, more and more of us will be jetting off to far flung destinations around the world. Whilst traveling by plane many of us will experience issues with our ears due to pressure.  In rare cases these problems can lead to severe pain and hearing loss, so it is best to take precautions, before, during and after a flight. 

As an Audiologist, I thought it would be good to explain what happens to our ears when we fly…

It really comes down to air pressure. Normally the air pressure inside the inner ear and the air pressure outside are essentially the same, or at least not different enough to cause any trouble. Even if you were to hike to the top of a tall mountain, the slow speed of your ascent would allow time for the pressure to equalise along the way. A problem only occurs when the change in altitude is so rapid that the pressure inside the inner ear and the air pressure outside don’t have time to equalise, as occurs in air travel. 

When your flight takes off, and begins its ascent, the air pressure inside the inner ear quickly surpasses that of the pressure outside. The eardrum swells outward. Picture a loaf of bread baking, and you get the idea. Conversely if air pressure inside the inner ear rapidly becomes less than the air pressure outside, the tympanic membrane (the eardrum) will be sucked inward, almost like a vacuum effect. What has happened is that the Eustachian tube (which links our ears with our throat) has flattened and needs a bit of extra help from you in order to continue to do its job of bringing air into the inner ear. Whether ascending or descending, that stretching not only causes the eardrum not to vibrate (thus the muffled sounds) but also causes the pain you feel. 

Everyone who has flown in a plane has felt the effects of a change in altitude on ears; a feeling of fullness and popping is commonplace. You need to equalise the pressure by introducing as much air as possible via the Eustachian tube and there are a number of ways to do that. 

The easiest way to equalise the pressure is to swallow. When you swallow, that clicking or popping sound you may hear is actually a tiny bubble of air that has moved from the back of the nose into the middle ear, via the Eustachian tube. The Eustachian tube ensures that the air in the middle ear is constantly being re-supplied. That air is then absorbed into the membranes of the inner ear, and the cycle starts over again. This constant cycle of air ensures that the air pressure on both sides stays equal. When you fly, the trick is to ensure that the Eustachian tubes work overtime and open more frequently to accommodate the change in air pressure. 

Chewing gum or sucking on a hard boiled sweet will help; for infants, whose Eustachian tubes are much narrower than an adult’s, the change in air pressure can be even more excruciating, so a bottle or dummy is recommended to increase swallowing. 

Other ways of equalising the pressure include:

• Avoid sleeping during ascent or descent
• Drink lots of fluids in-flight to stay hydrated
• Yawn
• EarPlanes: Specially designed ear plugs that have a filter to equalise pressure
• Nasal spray: Take only when needed as overuse of nasal sprays can end up causing more congestion

It's important to accompany a loved one to their hearing test

Having to live with an untreated hearing loss can be very difficult and a lonely experience. On top of finding it hard to listen and communicate, those who are hearing impaired often have to deal with increasingly frustrated family members and friends who are tired of repeating themselves. Personal relationships are adversely affected by hearing loss. Hearing impaired couples are hardest hit, but relations with friends, family and colleagues suffer, as well.

A British study among 1,500 individuals, aged 55 years and older, with hearing loss seemed to confirm that the presence of hearing loss is likely to cause marital strain. Almost one in two said that relationships with their partner, friends or family had suffered because they could not hear properly. A third had lost touch with friends, and in some cases marriages fell apart as a direct result of a breakdown in communication.
If you have a loved one hearing loss, it is important for you to be positive, supportive and committed to helping them improve their hearing.

One simple way you can support a family member who has hearing difficulties is accompanying them to their hearing test (instead of just losing your patience and badgering them to book one!) Here are four reasons why it is better to tackle the first hearing appointment as a team.

1. Solidarity and comfort
Most hearing evaluations last around 60 minutes or longer. Although there is nothing painful about having the hearing test carried out, it can still be a nerve-wracking experience – especially anticipating the results. Having a loved one there can ease anxiety and help the person with hearing loss feel less alone.

2. Better understanding of the results
It can often be confusing to understand the results of medical tests and their implications – especially when you can’t hear well or have other things on your mind. That’s why it’s nice to have a trusted friend or family member along who can take notes and ask appropriate questions while the audiologist interprets the findings.

3. Another view point
It’s not uncommon for family members to notice hearing loss in a loved one before they notice it themselves. It is very possible that a person with untreated hearing loss does not even realise how much they are missing. Bringing a family member to the initial hearing test will give the hearing clinician access to a different point of view, helping them to formulate the most accurate result possible.

4. Shared responsibility
Sometimes it is hard to make an important medical decision by yourself. When it comes to investing in a pair of hearing aids it’s a good idea to tackle key decisions, such as what type to purchase, what features would compliment their lifestyle and how much to spend, together.

It is also important that a family member is at the first appointment so they can be informed of their importance to their loved one’s hearing rehabilitation process. Persistent encouragement, a positive attitude and the implementation of communication strategies by family members will ultimately result in greater satisfaction for everyone. It really requires a family effort to get the most out of hearing aids.

Looking after your hearing aid this summer

Summer appears to be finally here. Many people look forward to this time of year because it gives them the opportunity to indulge in activities requiring warm, sunny days, like swimming, walking, cycling, and travelling.

Wearing hearing aids shouldn’t keep you from enjoying yourself, but it is important to remember exposure to high heat can damage their outer casings and interior components. Therefore, whether you plan to spend your days basking in the sun by the beach or pool, or visiting exotic destinations, you should prepare to keep your hearing aids safe and functioning.

Avoid extreme temperature changes. The plastic outer shells of hearing aids can melt if exposed directly to intense sunlight for long periods or in extreme heat, such as inside a car parked in a sweltering outdoor lot. Conversely, your hearing aids’ inner workings are more at risk from significant changes in temperature rather than heat or sun exposure specifically. This is because moisture condenses within the hearing aid as you go from a cool, air-conditioned environment into the hot outdoors, especially if you go back and forth repeatedly. As for hearing aid batteries, they are likely to fail if exposed to high heat for more than a short amount of time.

Here are two “dont’s” and one “do” for protecting your hearing aids from excessive heat:

• Don’t leave hearing aids lying out in direct sunlight
• Don’t leave hearing aids locked in a glove box or sitting on the dashboard
• Do store hearing aid batteries in a cool, dry place

Sun cream: good for you, not so much for your hearing aids. While it is important to protect your skin from the sun’s rays, you could inadvertently damage your hearing aids by doing so. Sun creams and sprays can clog vents and damage other components. It is advisable to put on sunscreen before you put in your hearing aids.

The difference between “waterproof” and “water-resistance” matters. You may have water-resistant hearing aids but understand this does not mean they can be submerged in the ocean or a pool. Water-resistant hearing aids help if you’re perspiring in the summer sun. However, if you jump into a lake wearing them, water will get inside through the microphone or other vents and they will be ruined.

Keep in mind:

• Don’t wear non-waterproof hearing aids if you’re going swimming, or anywhere else where it is likely they will get drenched
• Do make sure you know whether your hearing aids are waterproof or water-resistant
• Do invest in a dehumidifier pot to remove moisture from your hearing aids [link takes you to an external website]

This summer enjoy listening to the sound of the BBQ sizzling, children playing in the garden, and the birds singing in the trees. Just follow these simple do’s and dont’s to make sure your hearing aids keep up with your summertime lifestyle.

 

 

World's First 'Made for iPhone' Hearing Aid

I am very excited as I write this post because the world of hearing aids is about to be given a shake up. For some time hearing aids have had an negative image attached to them, but a new technology advancement is about to make hearing aids very cool indeed!

Danish hearing aid manufacturer, GN ReSound, has just launched its latest product 'LiNX' over in the United States and is due for release here in the UK later this year.

This new hearing instrument connects directly to iPhones and other iOS devices, allowing wearers to talk on the phone or listen to music, without any intermediary devices, and is the first of it's kind.

Launching alongside the LiNX is a new iOS app that works as a remote for the hearing aid, allowing wearers to adjust volume levels, equalisers, and switch between preset environments for the hearing aid, allowing the device to optimise to the user's environment.

Hearing aids can have several different modes, adjusting to the acoustics of each environment -- the app even uses geofencing to automatically change sound profiles based on the location of the wearer, changing for work, home, or a favorite restaurant. There is also a "Find My Hearing Aid" function to help users find their device if it's lost.

Previously, hearing aid wearers would need to carry a pendant or other wireless device in order to make changes to settings on a tiny hearing aid -- adjusting volume or switching between profiles -- now, users can make those changes directly on the iPhone, a device that many are carrying anyway in a significant quality of life improvement.

It also allows users to listen directly to games, calls, FaceTime conversations, music, and any other audio directly from the iOS device, without a handheld dongle or other intermediary devices.The technology will be available in hearing aids from both GN ReSound and its sister-brand Beltone.

Who said that hearing aids couldn't be cool?
