Antaeus' Pre-AM6 thread (questions and preparations)

[Antaeus]

So my sister and two nephews will be staying with us during the next two months during their transition to Tennesee. My sister and the younger baby sleep in the room next door to me. I plan on using the masked track for the most part. Will it cause a problem if the baby is in the next room or would he literally have to be in the same room as me to be affected negatively by the sub? Just taking precautions here.
