Light has a very high measure in Hz. (Trillions of Hz per second). Using the laws of harmonics one can continually divide by 2 to reduce the very high values to those that can be heard by us. With sound, every time a frequency is divided by 2 you get to the same tone one octave...
The proposed model enhances the signal detection ability and raises the performance level of vocal art, music art, and human body noise signal. The results of the simulation demonstrate that the proposed model enhances the signal acquisition capability of vocal music and the analysis of human noise...
It raises the question to what extent music can be considered as a kind of substitution for skin-to-skin contact, which brings us to the guiding question of this paper: can music listening be considered a kind of kangaroo care in some derivative way? Kangaroo care, however, is not merely...
