Hearing Aid Life Expectancy and Power

Our concept of age depends on the object of our attention. For example, the average ant lives to be about 45-60 days. The average fly lives about 15-30 days. The average albatross lives between 42-50 years.

Electronics must be viewed differently however. They cannot eat something and become more energetic. There is the total lifespan of the device coupled with the power required to maintain the function it was designed for. A television is expected to last about 10 years, but will not work if it is not plugged in. The average car battery will only be useful for 5-7 years. A watch battery can vary from 1 to 6 years.

With our daily electronics, we take advantage of all types of batteries. How long can you go before you need to recharge your cell phone? Now imagine you used the phone continuously. How about the electronic tablets? Technology is wonderful, but must be constantly powered. Batteries for these devices last only a matter of hours before we need to find an alternate power source. With the electronics we depend on, it is critical to know how long we can expect to use them. This is even more true when those electronics begin to age. Highly sensitive and detailed instruments are classic examples of those devices for which we need to know the total life of the device and its power consumption.

A hearing aid is an example of such a device.

Hearing aids can use both disposable and rechargeable batteries. The cost effectiveness and convenience will vary greatly. The predicted number of hours for each battery will be hearing aid, and person, specific.

Also: the ear is small. Therefore the hearing aid must be small. The battery must then be even smaller.

As with any battery driven electronic device, hearing aids last much longer than their power source. The average hearing aid lifespan will vary significantly due to the amount of care provided to it. Accidents can and do happen. When it comes to hearing aids, seven years may not appear to be a very long time, but the device is considered ANCIENT by that time. The average person is expected to replace a hearing aid every 3-5 years.

There are several reasons for this:

What is Gastroenteritis?

This past week, Britain’s Queen Elizabeth II was hospitalized with a “stomach bug”. Gastroenteritis (also called the “stomach flu”) is the second most common illness in the United States. So, chances are good that your family has been affected by gastroenteritis already this year!

What are the symptoms of gastroenteritis?
Gastroenteritis is inflammation of the stomach and intestines causing symptoms of diarrhea, vomiting, cramping, and fever. If a person is not able to keep up with fluid losses from diarrhea and vomiting, then they can become dehydrated. Gastroenteritis occurs year-round and affects people of all ages. Those who are young, old, or have a suppressed immune system are more susceptible to severe gastroenteritis and to dehydration.

What causes gastroenteritis?
The majority of cases are caused by a viral infection (occasionally, a bacterial infection) transmitted through contact with another sick person or contaminated food/drink.

I have gastroenteritis, how can I feel better?
Rest and fluids! Staying hydrated is the most important step to controlling gastroenteritis. Some good options for staying hydrated include sports drinks or oral rehydration solutions (such as Pedialyte in drug and grocery stores).

I typically do not recommend any anti-diarrheal medications as this may even prolong the illness. In addition, antibiotic therapy is not helpful unless a specific bacterial cause is identified.

When should I call my doctor?
If you have questions or concerns you should always call your provider. However, things to watch for if you have gastroenteritis include:
