While individual perception varies, there are several technical and psychological reasons that can explain this phenomenon:
1. Loss of Information and Artifacts in Compressed Audio (Lossy Compression):
MP3 and other lossy formats achieve smaller file sizes by discarding some of the original audio data that is deemed less noticeable to the human ear. While clever algorithms try to mask this, the missing information can still be subconsciously processed by the brain.
The "Loudness War": Many commercially produced tracks, especially in pop and rock, are heavily compressed during mastering (dynamic range compression) to make them sound louder and "punchier." This reduces the dynamic range (the difference between the loudest and quietest parts of the music), making the sound consistently loud and dense. This lack of variation can be incredibly fatiguing because the ear and brain are constantly stimulated without any "breathing room." It's like staring at a bright light without blinking.
Introduced Artifacts: Lossy compression can introduce subtle, unnatural sounds or distortions (artifacts) that weren't present in the original recording. While these might not be immediately obvious, the brain might expend extra effort trying to make sense of these anomalies, leading to mental fatigue over time.
