Your dog might not be able to hear, but he might be feeling sudden vibrations that makes him think he should bark, or alert someone to it. The door closing can make a thud sound, a truck out on a highway rattling by could be felt, or a neighbor chopping wood...things like that. Even the door opening, could cause enough change in air pressure, movement to startle your dog.
Try paying attention to sounds around you and see if that is what's setting him off. He might not have responded earlier because many dogs that are adopted and coming into a new environment are often under stress from it or from being locked up in a kennel environment for some time and they have kind of shut down in some ways. It can take a dog anywhere from 2 weeks to 3 months to start to show their own true personality after being adopted. Perhaps a deaf dog might take even longer, given you've had him for a year now.
Kudos, for taking in a dog most would pass up on. I took in a mentally handicapped Golden Retriever that I named HaHa, and he ended up being the best dog I've ever owned...and I've owned some very fine dogs in my life. He passed away last year though. I also have a feral dog, Jaya, and she'll never be the cozy friendly type around me or anyone.... I've had her for 6 years now and she barely tolerates me coming up to her still. But in both dogs, I got a great satisfaction in feeling like I uncovered hidden gems that others walked right past.
Jaya...as mentioned, is fearful of humans, but for me, she at least now shows me she's happy when I come home, she will trot in a circle with her tail up and waving. It's good though to see her relaxed like that and she even plays with my new Golden, AU, who's 7 months old...something I don't think she ever did before I got her. She and HaHa use to play a tiny bit, but not the running body slamming play that she and AU seem to enjoy.
I've had more than a few of my dogs go blind and/or deaf in old age, but I did notice that with most, they could/would respond to low frequency noises, like thuds coming from the Department of Transportation next to my home when a loader bucket hit the ground, or someone outside my home shutting a car door or even sounds from the t.v. set. So kind of keep an ear tuned in for things like that and see if your dog is responding to something real, and not just barking to bark.
