Sounds like he barks and lunges because he’s terrified of everything. I would start by reading “Guide To Living With & Training A Fearful Dog”

You will need to come up with a plan to build his confidence, increase his comfort zone with things, and in the meantime, give him space and manage his environment and situations he’s exposed to.
I’m sorry but I don’t understand what your question is? Please ask your vet about conditioning behavior training if your dog seems to be afraid.
It sounds as though your dog is fearful of the noise. With noise sensitivities, we can use desensitization and counterconditioning to acclimate the dog to the sound. We would start by playing the sound at a very low volume (low enough so the dog doesn’t have the fear response) and giving a treat about one second after the sound occurs. When we shut off the noise, the food stops. So, the dog learns that the noise predicts the food. You may need the help of a good trainer or behaviorist to do this conditioning, but the god news is that it can be very effective. We use this technique to get dogs to like all kinds of things they previously feared or disliked.
While this video doesn’t involve noise, it’s a good example of the procedure:
