I am now 28 week.I can't sleep these days .I feel sleep and I close my eyes and sleeping but I can here all the surround sound.its very uncomfortable for me what should I do now?

Maybe white noise would help. Buy an inexpensive machine for this or turn on a fan so the drone will cover any other noises. It might take a night or two to get used to the drone, but it will become part of your sleep routine before you know it. Some people use New Age music or a low-volume radio that clicks off after an hour or so.
