Using Audio-Visual Presentations to Learn about Nature

Hi, my name is Fern, and I volunteered as an inner-city school teacher after I finished college. Many of my students had never been outside of the city, and although I couldn't take them into the mountains or the forests or even on a field trip to a farm, I wanted to give them a semblance of that experience. I ended up using audio-visual equipment to simulate a natural environment. My students were able to see grass blowing in the wind, time-lapse videos of trees growing, and they were surrounded by the sounds of nature. If you want to use audio-visual equipment to teach kids about nature or any other subject, check out my posts. They will guide you toward excellence.

The Future of Hearing Aids: Self-Programable Hearing Aids

by Eugene Mitchell

The field of audiology is continually evolving. Over the years, hearing aids have greatly evolved to allow for a finer-tuned machine. One of the developments that scientists and doctors are currently working towards are self-programable hearing aids that do not need the aid of an audiologist or a wireless connection in order to calibrate the settings.

How Typical Hearing Aids Work

Currently, when you are fitted with a hearing aid, you go to your audiologist and have it fitted.

First, your ear is measured to ensure that the hearing aid will fit into your ear correctly and comfortably.

Then, your audiologist will perform a series of tests to determine which frequencies you can hear, and which frequencies you cannot hear. Your audiologist then uses that information to set your hearing aids so that you can pick up on the right frequencies. Your audiologist also uses that information to make sure that you are not picking up on any unnecessary sounds. The information the audiologist gathers during this exam is transferred to your hearing aids via a wireless connection.

Once you are at home, you can download a computer software program that allows you to report any issues with your hearing aids and to further customize the settings. This information is all conveyed to your hearing aids via a wireless connection.

How a Self-Programable Hearing Aid Would Work

Self-programable hearing aids would come with a few different sized domes and tubing in order to allow you to find the right fit. If you already knew the size you needed, you could also order the self-programable hearing aid in that particular size.

Once you fit the hearing aid to your ear, you would set-up the hearing aid yourself by following the directions that came with your hearing aid. There would be a button on the side of your hearing aid that you would have to press for a set number of seconds. Then, your hearing aid would make a specific sound inside of your ear. To calibrate your hearing aid, you would just have to push the button every time you heard the sounds.

You would follow this process for a series of different frequencies. Your hearing aid would have a tiny computer chip inside of it that would allow it to process this information from you and calibrate your hearing aid the same way your audiologist would do.

Uses for a Self-Programable Hearing Aid

If you have access to an audiologist, a self-programable hearing aid may not be that useful for you. However, a self-fitted hearing aid could be extremely useful to communities around the world that do not have regular access to an audiologist.

It could help individuals who suffer from hearing loss, but do not have continual access to an audiologist or to a wireless connection, still benefit from state of the art hearing aids. It could also help advance the technology that is inside of your hearing aid right now.  For more information, talk to a professional like Audiology Clinic Of Northern Alberta.
