PSP as an aid to preventing childhood tinnitus?

Does using a PlayStation Portable to help prevent tinnitus in your child sound stupid? Well, having background calming natural sounds at night time can help, silence is not good for  tinnitus for sure. And you can set the music track function in the PSP to play one track continuously, with the power from the mains (even take the battery out). Also good for children who suffer from nightmares, apparently especially the case with young boys so my tinnitus consultant told me recently. And the PSP gives off a little light too, so there’s your night light. And with a device your child is already relaxed with – hello! Anyone listening (sic)?
