It can be a problem. I find that this is one of the few drawbacks of these appliances. I usually cook my veges in the microwave, and pasta on the stove due to the noise factor. I could do these things in the TC, but I see it as only one of the tools in my kitchen that I can use, and I often choose the quietest one. However, I have been known to move the TC into the bathroom and shut the doors so I don't disturb anyone.
