Cheap way to improve your home ambience.

Yes, cheap and easy.

First, music. Background music. Try to look for relaxing music you had. Waterfall sound, ocean waves sound, or even a lounge jazz. Hey, boarding music played by airlines works too. You can just find them in YouTube and play.

Cheap and easy.
