Do external noises interfere with the brain entrainment component of the programs?

Question: I have a question about noise while you are listening to the programs with headphones. For example, if you can hear the hum of a fan or air conditioner while you are listening to the tracks does that interfere with the brain entrainment component of the programs?

Answer: As long as you have the volume at a comfortable range where you can hear the soundtrack clearly, distinctly and comfortably, then any noise in the background should not interfere. ~ ET
