Frequency dependent measurements of the quality factor Q typically show a\ud constant behaviour for low frequencies and a positive power law dependence for higher\ud frequencies. In particular, the constant Q pattern is usually explained using intrinsic\ud attenuation models due to anelasticity with either a single or multiple superposed\ud relaxation mechanisms - each with a particular resonance peak.\ud However, in this study, I show using wave localisation theory that a constant\ud Q may also be due to apparent attenuation due to scattering losses. Namely, this\ud phenomenon occurs if the Earth displays fractal characteristics. Moreover, if fractal\ud characteristics exist over a limited range of scales only, even an absorption band can\ud be created - in accordance with observations. This indicates that it may be very\ud difficult to distinguish between intrinsic and scattering attenuation on the basis of\ud frequency dependent measurements of the quality factor only
