bluetooth wireless technology allows wireless communication between electronic devices. bluetooth uses short-range wireless radio technology to connect devices to each other, generally within a distance of 30 ft. Newer devices may have ranges of over 100 ft. It eliminates the need for wires to be connected to all the devices, making it much easier to operate them.

Although bluetooth technology has been around for a while it is now becoming the new standard for most electronic devices. For those who wear hearing aids the technology provides the ability to use hands free devices along with the hearing aid. As most hearing aid users know, in the past, there have been compatibility issues with hearing aids and devices such as cell phone headsets and iPod ear piece. However, the latest technology incorporates bluetooth wireless technology into hearing aids, making them compatible with many bluetooth enabled devices.

bluetooth enabled hearing aids use this wireless technology twofold. bluetooth wireless technology allows for communication between two hearing aids. This helps to get the most natural hearing enhancement possible. The two hearing aids "talk" to each other to make instantaneous enhancements to improve hearing. Another exciting function of bluetooth enabled hearing aids is wireless connectivity with other bluetooth enabled devices such as cell phones and music players. This technology is a vast improvement over hearing aids in the past which were often incompatible with other devices.

Several leading manufacturers have developed bluetooth enabled hearing aids. Oticon's newest hearing aid range is called Epoq. It provides wireless binaural communication between the right and left hearing aids to make stereophonic sound more natural. Integrated bluetooth technology also enables the Epoq hearing aid to get mobile phone reception directly into it. This effectively eliminates the need for attached wires, which in the past was the only way to provide connectivity.

The Phonak's Smartlink uses integrated bluetooth technology to enable bi-directional digital link between the hearing aid and a bluetooth enabled cell phone. An external audio input or microphone signal can also be transmitted wirelessly via Smartlink to the hearing aid by attaching to the smart interface.

Starkey Laboratories offers the Eli hearing aid, which incorporates bluetooth technology allowing communication between hearing aid users, and the growing assortment of bluetooth enabled devices such as a cell phone. The Eli is the smallest bluetooth enabled hearing aid on the market.

Those who are shopping for their first hearing aid will do well by purchasing one with bluetooth technology. No matter what your needs, bluetooth technology is the wave of the future and will enable you to connect easily and wirelessly with many devices. All of the major hearing aid companies are developing their own hearing aids that utilize Bluetooth technology.

Thanks to decades of dedication by teachers who have brought environmental topics into the classroom, todays students are more educated about ecology and the natural world than ever before. And now, thanks to Hurricane Katrina, the hurricane and resulting flood that devastated a large part of the Gulf Coast in the summer of 2005, environmental issues have hit the front pages of newspapers and prime time TV newscasts. The environment is big news. And for a lot of kids, its scary news.

global warming; polar bears facing extinction; colonies of bees dying all over the U.S.: these and other stories on TV have the potential of upsetting school-aged children. For teachers, this can be a big problem, or it can be an opportunity to engage children, to inform them of the problems and their possible solutions, and to excite children about scientific topics and procedures.

Luckily, written and video material abounds that teaches children about science and the natural world. books, magazines, and DVDs are available that cover every conceivable topic. Teachers guides are available for many of the periodicals, offering suggestions for incorporating the material into the class curriculum. Much of this material is geared toward current environmental concerns.

Yes, the environment is a big, scary news story right now. But with the right material and a creative approach, teachers can redirect their students fears to learning, to scientific knowledge and to developing an activist approach to the world that may send some of these young people into the direction of solving many of these serious worldwide problems.
