Will using bluetooth a lot drain the battery of my Samsung tablet?

I have a Samsung Galaxy Tab 3 7.0 tablet that I keep with me at work all day. I use it almost exclusively to keep an eye on the stock market and not much else. I'm thinking about getting a speaker that has bluetooth capability that I can let my tablet play music through during the day while I'm working. I have used a radio for years and the stations I like to listen to have a poor signal in my area but I can listen to them through my tablet on iheart radio.

I was wondering, how much of a drain this will be on the battery of my tablet? It will be transmitting a signal up to 8 hours a day with the screen being used occasionally as I check my stocks or change the station. I think it will be ok but I wondered if anyone else had much experience with using a tablet this way.

Thanks for your advice and input!
