Rub & Buzz testing in FINE QC Danish F. Leonhard derived in 1993 a new auditory model how the human ear perceives sound. The FINEBuzz detection method was introduced in 2008 using an improved algorithm that finds all the annoying sounds, which cannot be detected by THD or IM. Loudspeakers with Rub and Buzz have high irregular noise distortion. The enhanced 3 rd generation FINEBuzz algorithm finds all impulsive noise in the signal using very advanced High Pass filtering. These signals are often 80110 d. B below test signal. FINEQC measures Rub & Buzz with very fine correlation with listening tests. See paper ISEAT : Fast Rub & Buzz Testing, Peter Larsen
