Too much talking

My husband and son talk a lot. They talk to me a lot. I am an introspective person who likes to think. I find that they talk so much either around me or to me that I feel stressed out. I know i caould change my thought to aomething like “i am happy i have a husband and son to talk with” which is true. I was wondering if you think its ok for me to explain to them that i like to be quiet and have a lot on my mind right now and ask them to limit their talking to more relevant things. They also talk a lot a out politics and racing cars and my husband constantly telling me about what happens at work- always negative- but neither of them are asking for my input nor do they seem to want it.
