Senza System – The Results

It’s been a long time coming, but I’m finally ready to release the results of my study. I’m sure you’re all dying to see them, so without further ado, let’s begin…

For those of you who haven’t been following my series on this, you might want to go here for the introduction and then here for the methodology of the experiment. For those of you too lazy to read my previous articles, I’ll give you a quick recap. The rest of you can skip the next paragraph.

We made a series of recordings in a low resonance room, first using senza strings and then using normal dominant strings. The recordings for the senza strings were then averaged out, as were the recordings for the dominant strings.

The following graphs will show the averages of each string type for each set of recordings. The senza strings are the red line, while the dominant strings are white. I will use the open A at 220Hz for the purpose of the explanation, but the full results will be posted at the end of the article.

The y-axis show the frequency and the x axis the intensity. As you can see, the senza system produces an overall louder and more defined sound.

If you look through all the results closely, you will also notice that the main difference is on the lower octaves, with the difference getting smaller the higher you go.

Another point of note is the at the highest frequency of each note, the senza graph shows a clear and defined comb as you get right through the spectrum. The dominant strings, however produce a much less defined, almost noisy graph.

I think the results speak for themselves, but it’s definitely down to a personal preference. You’ll never know unless you try for yourself.

    Sehr interessant. Gibt das Diagramm Durchschnittswerte von allen gemessenen Instrumenten wieder?

      Hi Jan,
      richtig, das sind die Durchschnittswerte von allen Messungen.
      Sechs verschiedene Instrumente pro Setup zwei mal aufgenommen.
