Since their inception there has been a steady noise that gets louder upon occation. It is a steady hum that never ends. When it gets louder, you can hear it through the closed windows even more. I talked with them a few times in the beginning and was always told they were correcting the problem. It did get quieter for a bit, then louder, then quieter, then louder. You get the gist. The steady hum is still always there. The last few days it was quite loud again. The neighboring area has complaints too, not just me. Now they plan on adding another machine, so more noise? It is time something was done about this. There are laws about noise after hours for all the citizens, why not the companies?
