We're going to experiment with Lotte's FM equipment.
We have had it for a while, but since she didn't have problems in the classroom, we decided to wait a bit... That's.. until now. Time to experiment.
On my search for some explanations about the equipment I came across this webside..
Nice site to give an idea about using FM in a classroom with noise.
Have a try... . Adjust the parameters. For example - distance to the teacher... and the noise. Then turn on the FM-equipment....
Impressive demo... Not sure how real the situation is... perhaps readers that have CI and use FM may confirm that it's a good demonstration....
Some linke (Thanks Dan..)
