I was hoping for a response to my information request but I don't want you to go without an answer either.
It is likely your dog associates the front part of the house with all the noises associated with the new year such as gunshots, pans clanging, noise makers and even fireworks. You might not have even heard all the noises your dog did since a dogs hearing is much more acute than ours.
This would not be as much of a noise phobia as an anxiety issue related to the room where the "incident" occurred. So I would recommend tempting her as much as possible to enter those rooms so she can see that the cause of her discomfort or fear no longer exists in those areas. You might leave a trail of tasty treats (not boring store bought ones) such as paper thin hot dog slivers in a trail to the edge of the area she wont' enter. Do this a few times a day. Gradually let the trail come into the areas she isn't comfortable in. Let her gradually see that there is nothing to worry about in those areas anymore.
Some will recommend forcing her to enter those rooms to show her there is nothing there, but that "flooding" doesn't always work and can actually make an anxious dog even more anxious. Now a DAP collar might be helpful. They have been proven helpful for things like noise phobias, separation anxiety, car rides, etc so it is worth a try. they produce a pheromone much like the one a nursing mother produces to calm her pups. They are available at pet stores, vet offices and online.
Another option is obedience training. You can reinforce her training especially with the recall or come command and leash training. Reinforce these commands and then use them to get her to walk into the room remembering to reward her coming into the room with the tasty treats so she starts associating the rooms with good things rather than whatever it was that happened that night.
