About CD. 

The sounds collected on this CD have been proven to stimulate infants' development. Continuous tracks, 99 in total and no more than 30 seconds each, contain sounds of nature, animals, various instruments, and compositions by classical giants. Total running time is approximately 55 minutes. 

The CD has been mastered professionally in a state of the art studio, and is manufactured by a leading CD manufacturer in the USA.

We have conducted numerous tests, working with families with children under 1 year of age, and almost all infants responded to many of the sounds very positively. The non repetitive cycling nature of the compilation makes it an easy listening for parents as well as older kids in the family.
