First
In recent years, living things have got so many varieties of stresses that they have never had before. When you get stressed, you will have so many types of affect to your body like; automatic nervous system, adrenal cortical hormone, elevation in blood pressure, elevation in blood sugar level and deficient in vitamins and so on.
On the other hand, music promotes the body’s metabolism, and it also affects muscle weakness and develops muscle strength, and it also affects to the mount of blood, blood pressure, and number of pulses and it adjust vitamin consumption.
So, we set up three types of stimulus; Mozart, white noise and silent condition. Then , we researched about the acoustic stimulation differences how it affects to blood lactate level, thiamine concentration and the peroxidative response of brain lipid, and we checked how they affect to living things stressed conditions.

experimental methodology
We use 15 of 7weeks old male rats in the experiments. Three patterns of acoustic stimulation would be Mozart-Requiem K626 which is widely used in the music therapy of stress, and as a noise model we used white noise which we took from TV. And for stressed model, we set it up to the model of summer fatigue which will be often seen in high-temperature and humid summer seasons. We set up the environmental temperature to 31-32, and humidity to 85%, and made the high temperatural stressed model to the rats that are normally living in 25+/-2.
Under the environment, we divided 15rats into the three groups, Mozart heard group, white noise heard group, and silent group, and let them hear two hours in one day for each. Then, we researched about the effect that acoustic stimulations will affect to this high humid- high temperatural stressed situation.

experimental result
3.1 liver thiamine concentrations

The group which had acoustic stimulations had significantly high liver thiamine concentrations compared to the average of the silence group.
3.2 Blood lactate level
The group which heard Mozart had significantly low average lactate level compared to the white noise heard group. And the group that heard white noise had significantly high lactate level compared to the silent

3.3 peroxidative response of brain lipid
Mozart heard group had significantly low peroxidative response level compared to the white noise group in brain. And in brainstem, the acoustic stimulation groups had significantly high peroxidative response level compared to the silence groups. This could be thought that the high humid-high temperature environment stressor and the acoustic stimulation made more stress, and this made more of peroxidative

Conclusion
We found out from the liver thiamin concentration that in the acoustic stimulation environment, they had low thiamine consumption compared to the silent environment. Also, we could find out through blood lactate level and peroxidative response of brain that the Mozart heard groups have lightened up stress effect compared to the noise heard groups. We can see from the above that the relations between stress response and the fractional characteristics acoustic stimulation have suggested.
