My guess is that the brain add the missing sounds in lossy compressed music/sounds to make up for the loss and to filter out some of the blurs and distortions (in high bands). If you would only hear lossy compressed sounds, from the very beginning of your life, your mind would be tuned to this and you would have problems hearing "real" sounds, or they would sound "weired". If this is a big (potential) problem, I would not know. But I think it must have to do with huw much you expose yourselfe to lossy sounds and how lossy it really is (eg. MP3 64kbit or OGG -q 10). Just my thoughts. Flame away :) Best regards, Andreas Karlsson --- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.

The human ear has been artfully designed and carefully tuned to detect the slightest movements of predators or characterize their surroundings through the types of sounds they heard, and later to recognize and reproduce the fine nuances in the sounds of others' voices. Contrast this to the ear's experience at a rock concert. Whether through the maze of processing in sound recording equipment, arbitrary equalization, distortion, or even the discrete voltage levels of digital processing, nearly all recorded sound is totally unnatural. There is much more to sound than what you hear on the surface, but it is on such surface that all "psychacoustic" judgements are made. I think that the article, while written in a somewhat confusing style, makes a valid point. However, scientifically studying this problem may prove difficult, if the problem truely exists and indeed is not masked by the noise of other artificial causes. (Note how aural terminology has entered the mainstream of language!) Disk space is cheap. I'm doubling my quality level from now on. having spoken thus, Ken On Sat, Dec 21, 2002 at 01:48:48AM -0800, Chris wrote:> Unintended Consequences of MP3 Compression to Hearing: > http://www.informatik.fh-hamburg.de/~windle_c/Logologie/MP3-Gefahr/MP3-risk.html > > Based in some real facts or just someone makeing stuff up? > > Chris-------------- next part -------------- A non-text attachment was scrubbed...

I posted a reply, but this falls into the same bucket of 'Use MP3 because Vorbis can damage your speakers!' nonsense that came up a few months ago.

Reminds me of all these health warnings we get on the news. They say that if we heeded all the warnings we'd have nothing to cook with, indeed, no food to cook in the first place. Can listening to Vorbis-encoded music be much worse for us than listening to music that's been "cleaned up" using FFT-based noise reduction? Because it seems to me they do much the same thing, only Vorbis is a bit more intelligent than a typical FFT NR. Even so, I remember a friend quoting a study that found tape hiss & vinyl noises to be soothing in comparison to the "clean" sound of CDs. :-/ - Shawn <p>Chis wrote:>Unintended Consequences of MP3 Compression to Hearing: >http://www.informatik.fh-hamburg.de/~windle_c/Logologie/MP3-Gefahr/MP3-risk.html >Based in some real facts or just someone makeing stuff up? >Chris--- >8 ---- List archives: http://www.xiph.org/archives/ Ogg project homepage: http://www.xiph.org/ogg/ To unsubscribe from this list, send a message to 'vorbis-request@xiph.org' containing only the word 'unsubscribe' in the body.
