	MP3 can cause hearing damage

	Ear damage by MP3, DVD and digital television? -risks of neuroacoustically datareduced music Nowadays technologies for lossy data compression of digital audio recordings get widely used in more and more applications. This way methods like MP3, WMA, MPEG and ATTRAC are not only used for memory saving music downloads through the internet and comfortable use on portable players, but they are also employed for background musics in modern videogames and already today they are used in ordinary radio stations to store all kinds of audio material on harddisks to permit comfortable access for broadcast. Due to such technologies are also employed in DVD films and all common digital video systems (those are widely used for TV broadcasting), and because it is even planned to replace soon the entire analogue television system with digital TV (DVB) that is based on these technologies, and also to digitize the radio broadcast this way, it is strictly necessary to precisely research on the health risks of modern data compression methods. Unlike with compression and decompression of computer programs (e.g. ZIP), that is to say, during lossy data compression (data reduction) the original signal is not reconstructed 1:1, but to reduce the data amount, only control signals for a synthesizer programs (called CODEC) get recorded, those are optimized in a way that during rendition the CODEC can reconstruct from these an approximation of the original picture or sound signal that appears as similar as possible for the human conscious perception, but is not identical to the original signal. The danger of this exploitation of human perception flaws is that especially by lossy audio data compression sound portions get systematically destroyed, those although the brain would not pass them to the conscious awareness, are likely necessary for the human hearing's own perpetual calibration. The basic principle of modern audio data reduction is, that is to say, to omit during storage exactly those sound portions those an average human being would not consciously perceive. The white science likes to call such methods gladly playing down "psychoacoustic", although in fact they have really nothing to do with psychology of sounds (e.g. the realization of noises as pleasant or unpleasant etc.) because their impact is on a far lower neurological level since they function on a model of the cochlea in the human ear and thus need to be called correctly "neuroacoustic" data reduction.
