Sleep sound machines are marvels of recent history. Being lulled to sleep (and hopefully, staying there) is the goal of placing one of these items in a senior citizen’s bedroom. Your elderly loved one can choose which sound they would prefer to drift off too – either a soft rainfall, the tweeting of birds, or a babbling brook among other. These types of sounds have all been soothing to us in our youth and may well invoke memories of gentler days. As your senior citizen’s hearing wanes, simply turn up the volume.
