Some are noisier than others. I watched a demo of a machine, I think it was a Nolting, and was absolutely turned off by how noisy it was. Innova and Handiquilter seem to be a bit quieter.
I don't watch tv while sewing and quilting, I watch Netflix on my computer with noise-cancelling bluetooth earbuds. The buds form a seal in my ear canal that greatly reduces outside noise, which means I don't have to turn the sound up as high.
