Are White Noise Machines Safe For Babies?

We have had a few of people in the past ask us if keeping a sound generator on throughout the night in their child’s room would cause a hearing loss. Recently, one of my friends sent me this article so I thought I’d set the record straight. A noise generator set to a soft level will NOT cause your child to develop a hearing loss, even if it plays all night long.

Babies are used to noise in the womb so it makes sense that some background noise, like white noise, can help some babies fall asleep. The article is based on a study that was conducted at SickKids Hospital, which simply stated that the maximum volume level of the noise generators that they tested, were loud enough to cause a noise induced hearing loss. My advice is to buy a noise generator with a sleep button that turns off after a half hour and keep the volume below conversation level. Sweet dreams babies!

Why are Hearing Aids/Hearing Instruments so Darn Expensive?

Long gone are the days when ear trumpets and animal horns were used to transmit sounds to the ear.  Today, hearing aids are essentially mini computers custom programmed to your hearing loss.  The signal processing speed of is so fast that your brain will not even notice that the sound has been changed to meet your needs.  Modern digital wireless hearing aid technology includes noise reduction algorithms and directional microphones to help you hear better than ever in our noisy world.  Aside from the advances in microelectronics that make them almost “invisible”, hearing aids today also have connectivity capability with other audio sources.

Bluetooth technology is now available in most hearing aids.  This technology turns your hearing instrument into a hands-free cell phone device through the use of a small intermediary accessory.   This is especially handy when driving since it not only frees up your hands but allows for crystal clear hearing.  You can also stream sounds from anything that is Bluetooth compatible, like music from your iPod.  Your mini computer of a hearing aid today also comes with a remote control.  You can control volume, turn your hearing aids on and off, answer your phone, adjust TV volume levels independently from others in the room, and listen to your tablet or MP3 player all with a click of a tiny pocket device. Many hearing aid manufacturers also have apps which allow you to turn your iPhone, blackberry or android smartphone into a remote control.

A hearing aid computer chip acts like an artificial intelligence scanning the sounds in your environment to reduce background noise and increase the speech sounds you are not able to hear.  However, this only helps if the person you want to hear is close to you.  There is a solution though for those who need to hear a person at a distance in a noisy environment, such as a church, synagogue, mosque or other places of worship where music and side conversations may be present at the same time.  In these cases, your hearing aids can be paired with a small discrete clip-on microphone anywhere within close range of a speaker’s voice.  The microphone delivers their voice directly to your hearing instruments with beautiful clarity.

People are often surprised to learn that hearing instruments/aids cost several thousand dollars.  Hearing aid manufacturers are not trying to gouge the public.  They need to invest significant amounts of money into research and design to make hearing aids faster, smaller and better at helping you hear.  In the end, there really is no price on better hearing.  It is one of our five senses and crucial to our ability to stay connected with one another.   Protect your hearing and we will help make the most of what is left with technology and our professional expertise.

Airplane Pressure and Hearing

Travel Can be a Pain – But Not for Your Ears

Hearing Airplane Pressure
Ear pain or discomfort is a common experience during air travel, especially during landings. Have you ever noticed your water bottle change shape during the flight? That’s what happens to our ears.

The pressure in our middle ear is different from the pressure in the environment. Our eardrum, the membrane in your ear canal that separates your outer ear from your middle ear, changes shape and hurts our ear when the system isn’t working right.

Fortunately, our bodies have a tube that connects our middle ear space to the back of our nose and upper throat, called the Eustachian tube. This tube equalizes the pressure by allowing air to flow in and out of our middle ear space. We can relieve the pressure by manipulating our Eustachian tubes, like slowly opening the cap of the water bottle. You can “pop your ears”, or open the Eustachian tube, by either swallowing or yawning, which moves your jaw forward and down. But sucking on a hard candy, chewing gum or sipping on water may not make up the difference in pressure quickly enough during a flight.

When elevation quickly changes, as it does when flying, scuba diving, or driving in the mountains, it creates a vacuum in the middle ear that pulls the eardrum inward. This can also occur when airflow through our Eustachian tube is restricted, like when we have congestion due to allergies, colds or an inflammation. This is called ear barotrauma. Common symptoms are a sensation of fullness (as if underwater), ear discomfort or pain, slight hearing loss, ringing in the ears and sometimes dizziness when standing up. If the condition is very bad or goes on for a long period of time you may experience nosebleeds, vertigo, or a perforated eardrum; however, these conditions are rare during commercial flights.

If your ears feel congested or blocked due to a cold or other ear condition, it may be better to reschedule your flight. However, you may not want to or even be able to cancel a holiday or business trip just for this reason. There are products, techniques and treatment options that can reduce your chances of getting ear pain during the flight.

One technique you can try is called the Valsalva maneuver. It involves inhaling, then gently exhaling while holding the nostrils closed and the mouth shut. Be careful not to blow too hard, and stop as soon as one ear “pops”. If you blow too hard you can tear your eardrum, become dizzy or even cause auditory damage due to over-pressurization of your middle ears. Taking a decongestant one hour before a flight and/or using a decongestant nasal spray may help with ear pain if you are an adult. Antihistamines may also help if you have allergies. Always speak to your family physician or pharmacist before taking these drugs, as they do have some side effects.

The funniest home remedy I’ve heard of to date involves wetting tissue with hot water and placing one in each coffee cup, which is then placed over your ears. Pressure earplugs are a simpler and dryer solution. They’re special disposable earplugs that have a patented ceramic filter that slows down the pressure change, giving your ears additional time to adjust.

I use a brand called EarPlanes. They also have a noise reduction ratio of 20dB, which protects you from the loud sounds on the airplane. They’re good for two flights and can be found in both adult and children sizes. But make sure you follow the directions on the box! It’s not as simple as just putting them in your ears. The best place to purchase them is from an Audiology clinic, like our clinic at Salus Hearing Centre, where an Audiologist can answer any questions and even demonstrate how to use them properly

Here’s to starting your next land, air or sea journey with less “pressure!”
