The soundscape is changing day to day. There is a dynamic relationship between the men and the environment. Noise pollution is stemmed from careless. Because people do not listen carefully and they learn noise-sound should be ignored. It is deeply negative approach and it should be damaged. For this reason, boring and destructive music should be eliminate for ear cleaning and an acustic design should develop and the point is that people should be encourage.
Firstly, the definition of music has radical change in recent years. Because, technology is quickly developing and the world is actually changing. Therefore, the perception of people is changing and relatedly the perception of music changing. In recent years, the definition of music is that it is a sound and the sounds mean what we hear around us. In the West, the ear has given way to the eye as the most important gatherer of environmental information. Namely, we have come to imagine God. Previously, the God is not portraiture and it is perceived as a vibration or sound.
Secondly, human’s ear is an alert and a hi-fi system is a process to noise ratio. In the hi-fi soundscape, the sounds can be heard clearly because of low ambient noise level. The country is more hi-fi than the city in general. Also, the night is more hi-fi than day. Ancient times is more hi-fi than modern times. In a lo-fi soundscape, individual acustic signals are obscured in an overdense population of sounds such as a footstep in the snow, the train whistle in the distance, a church bell across the valley. It is masked by broad-band noise and the perspective is lost. Because, everything is close-miked and there is no distance.
In addition, the industrial revolution began to produce the lo-fi soundscape. When industry firstly intruded into town life, it was immediately conspicuous by the aberration of its novel noises.
Schizophonia refers to the split between an original sound and its electroacustical transmission or reproduction in the early 20th century. People have to split the sound from he maker of the sound. Every sound is unique. In this century, people have the ability to dislocate sounds in time as well as in space.
Eventually, the desire to dislocate sounds in time and space has been evident for some time in the history of Western music, so that the recent technological developments are merely he consequences of aspirations that have been building for some centuries. When we notice that the noise is in the mind, we begin to change everything around us.
