A soothing sound for one person may be an unbearable sound for another person.
A trial and error process is needed to figure out what sounds are calming for each individual.
Our current research indicates that three types of calming sounds predominate. These types of sounds are:
1. Nature sounds, especially running water
2. Favourite nursery rhymes
3. White noise
The good news is that all these sounds are available for download. Here are a couple of recommendations for making your own sound track:
