You could go to the HD and pick up a couple of remote control Christmas light switches. Press a button in the house and a blinking bright light and a buzzer plugged into it goes off in the shop. $10 for the remote, a few bucks for the thrift store light with a $5 flasher button and some kind of buzzer. Get a second Cristmas light gadged on the same frequency and voila, you can turn it off from the shop.
As to hearing aids, in the USA, Costco has state of the art aids for a little as $1,400 a pair. Good ones too. Don't wait too long to start wearing them, your comprehension of speech deteriorates if unused.
The more I do, the less I accomplish.
