T.V. volume

My husband doesn't sleep very well at night so of course he goes to the living room and turn on the T.V. which is fine with me as long as he keeps the volume down. But you know the commercials they all come up louder and wake me up.  I think I'm going to buy him one of those ear amplifiers just for watching T.V. at night or a wireless headset so I don't need to hear the sound at all.
