This is only true at very low, very poor quality, bitrates,

For good encoders (such as LAME VBR at = 160K) no

"tones are left out". The only "perceptual" feature
is how the encoder distributes highly colored noise.
At very high bitrates the noise becomes pretty much
high frequiency rolled off white noise.
