Well, a certain level of habituation can sometimes be seen - especially when the exposure isn't constant and the level is rather low. But the process can take years and is influenced by many factors. If sleep quality is good and blood pressure & cortisol levels are ok, one might consider "waiting it out"... if secondary effects increase, additional stress sources (job) pop up or relationship trouble starts, moving might be the smartest option. Another way would be to do a survey in the neighborhood and if other people are affected, collecting some money and hiring a acoustician with a proven track record of solving LFN cases to find the source. Once the source is identified, searching for a solution would be the next step. Sometimes simple things like swapping a fan in an air chiller can make a huge difference.
