Sounds during meditation

When I practice meditation I focus on the rising and falling of my abdomen and if any thoughts or sensations arise I note them and continue focusing in the breath but I notice that I'm very sensitive to sound. I am acutely aware of all the sounds going on around which is a never ending cacaphony of nearby people, traffic, wildlife etc. I was using earplugs for a long time because I found it too distracting but I decided to stop using them and now I am finding the sounds very much in my awareness a lot of the time and I can't seem to focus on my breath. So I note "hearing hearing" but like how long am I suppose to keep noting hearing ? If I sit for an hour and the sounds keep capturing my attention do I just keep noting hearing hearing every few seconds in the same way I do for thinking thinking?
