Impact Analysis of Sounds of Nature (Music Therapy) on the Hemato-Biochemistry of Homo sapiens and Rattus norvegicus

Pleasant music and natural (acoustical environment), as a stimulus has different properties on livings specially humans. The first property is that music is a discriminative stimulus, in other words humans have the ability to discriminate various styles of music and no one can deny that of music has a pleasurable or reinforcing property. Music induces mood change in either a depressive or a vigour direction. The acoustical environment can be defined as combination of both natural sounds and cultural and historic sounds. Because the acoustical environment is made up of many sounds the wellbeing of acoustical environment depends on interactions between the amplitudes and frequencies of all the sounds. Understanding these interactions is vital in protecting the acoustical environments for current and future generations. Properly balanced acoustical environments are vital for the natural functioning of all livings. Many natural sounds have a calming and relaxing effect. The symphony of natural sounds within our national parks is an important natural resource and a critical component of the ecological communities. When a bird sang or a mammal or amphibian vocalised, the voices appeared to fit in relation to all the natural sounds in terms of frequency and prosody (rhythm). Animal and insect vocalisations tended to occupy small bands of frequencies leaving "spectral niches" (bands of little or no energy) into which the vocalisations (fundamental and formants) of other animals, birds or insects can fit. In our studies over albino rats and humans, we observed that the natural sounds have their impact over the normal physiology by altering the levels of biochemical and haematological parameters such as significant decrease in serum total cholesterol, non- significant decrease in triglycerides, non-significant decrease in VLDL and LDL, significant increase in HDL in most cases. The decreases of various lipids are indicative of good health. so, we can say that all natural sounds in an ecosystem interact to each other and maintain a unique and balanced wildlife and ecosystem. environment. Because the acoustical environment is made up of many sounds the wellbeing of acoustical environment depends on interactions between the amplitudes and frequencies of all the sounds. Different sounds interact in interesting and sometimes surprising ways to determine the health of the environment. Some frequencies may block out or "mask" other frequencies, and some sounds may highlight or enhance others. Understanding these relationships is vital to protecting acoustical environments and soundscapes for current and future generations. Properly balanced acoustical environments are vital to the natural functioning of park and forest ecosystems in a number of ways including: Courtship and mating, inter and intra specific communication, proper metabolism and territory establishment finding effective habitat. When a bird sang or a mammal or amphibian vocalised, the voices appeared to fit in relation to all the natural sounds in terms of frequency and prosody (rhythm). : Animal and insect vocalisations tended to occupy small bands of frequencies leaving "spectral niches" (bands of little or no energy) into which the vocalisations (fundamental and formants) of other animals, birds or insects can fit. In the present study it has been found that each natural sound has its far reaching effect almost on all aspects of an animals life and in integrity, for the maintenance of ecological sustainable development. The conclusion is based on our studies over albino rats in which we observed that the natural sounds have their impact over the normal physiology by altering the levels of biochemical and haematological parameters.
