A jury of experts from the music world had to judge the sound. They also did not know which instruments were involved. The order was only determined just before the experiment and one of the instruments was performed twice to see if the scores would be the same.
Opinions differed about which violin had the best sound. Both the carbon fiber and flax fiber violins had instruments that scored well. As expected, the violin with wooden soundboard scored well, but not significantly better than the composite instruments.
Duerinck also received various answers to the question of how the perfect violin should sound. Many participants mainly wanted a warm or rich sound, for others a clear or round sound was important in the first place. Tim Duerinck: “This experiment shows that you cannot just shave all composite materials over the same comb. Much depends on the precise material, composition, weaving technique, …, but also on the listener’s preference. It is not true to say that carbon fiber violins cannot sound warm. You can make many different types of violins with carbon fiber. ”
