The paper compares the process and results of two different methods of performing rankings of a quality of musical instruments voices. A dedicated software tool enables the presentation of recorded sounds to the expert who makes his/her assessment according to particular criteria using a multistimulus test in a scale from 1 to n and a pairwise comparison followed by Net Flow Scoring method (NFS). Several aspects of the process have been analyzed, e.g. consistency of the results for both methods, stability of rankings over time (using Kendall’s coefficient values) as well as an assessment of cognitive effort from the expert in each ranking method. Multistimulus test appeared to be easier to perform but less distinctive than pairwise comparison.
