I'd just like to add that we are lacking a lot of research in Canada on this topic. Again, for years there have been many research studies done on noise, linking noise, obviously, with permanent hearing loss.
In the U.S. there have been recent studies to show that permanent hearing loss is on the rise among school-aged children, close to 12%, actually, of school-aged children. This is being linked to certain behaviours, such as the use of iPods and other MP3 players. We can only extrapolate that it's the noise factor that is the common denominator.
That's what's going on with the toys. These levels are just beyond what is necessary and beyond what is safe.
