Capturing binaural room impulse responses for high-quality auralization purposes requires a signal-to-noise ratio of >90 dB which is unattainable with MLS-measurements due to loudspeaker non-linearity but fairly easy to reach with Sweeps due to the possibility of completely rejecting harmonic distortion. Before investigating the differences and practical problems of measurements with MLS and Sweeps and arguing why Sweeps are the preferable choice for the majority of Measurement tasks, the existing methods of obtaining transfer functions are reviewed.
