Sometimes my voices stop for a while when I find something to completely interrupt them. For example, blasting music through headphones for like 10-15 mins at a time. The voices never seem to talk louder than the music. But that may not be the case for you. IDK. I know it's not good to blast music in your ears, but that's just what I do. For me, volume matters. Low volumes mean the voices can talk over them.
