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

Hear better than ever with Siemens binax hearing aids

Siemens is lifting binaural hearing systems to a new level. For the first time, hearing-impaired individuals can now hear better than those with normal hearing in particularly demanding listening situations*.

Despite their enormous computing power, the new Binax instruments are the most energy-efficient in their class.

Binax exchanges audio signals. Each binaural hearing aid can assess the acoustic environment not only on its own side, but also on the other. In the process, four microphones – two in each device – form a virtual eight-microphone network. New calculation methods work much like the human brain in leveraging the fact that voice signals don't reach both ears at the same speed or volume. Based on such differences, wearers can more accurately identify and focus on the sources of sound.

Binaural hearing aids also use this new technology in windy locations ideal for those golfers and outdoor patients. They automatically determine which side is receiving better signals and replicate them for the other device. These latest Siemens binaural hearing aids are capable of transmitting around a thousand times as much data per second as preceding models.

The new peak performance does not come at the expense of battery life and they can run on conventional hearing instrument batteries or, depending on the model, on rechargeable batteries.

Karen's comments: “We have had amazing success with the last Siemens technology platform called Micon and this new level is so exciting. My team and I can't wait to get started and see how this technology performs and improves peoples lives.”

If you would like to be amongst the first trialling these new instruments, please give our customer care team a call and book your appointment - Freephone 0800 096 2637.

*Two clinical studies have shown that binax provides better than normal hearing in certain demanding environments (Northern Colorado University, 2014; Oldenburg Hörzentrum, 2013): Speech Reception Thresholds in cocktail-party situations improved up to 2.9dB for wearers with mild to moderate hearing loss using Carat binax or Pure binax hearing instruments with narrow directionality, compared to people with normal hearing.

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.
