Heterodyning

[Brandon Pattison]

Did anyone see the TBM Tip of the Week describing this? Pretty cool theory.

I've been setting up my bows that come out of my shop this way for the last 4 years. Works great.

I'll have to try that, thanks for the tip. My Talltines isn't loud by any means, but everything helps!

Interesting. Never heard the term heterodyning before. I used wave principles and harmonics to place my string silencers. The 2nd harmonic has antinodes at 1/4 and 1/4, which is why I put my silencers at 1/4 from top and 1/4 from bottom rather than 1/3. However, in reality you see a combination of harmonics and frequencies. I might try this out and compare the total sound output... string silencers at 1/4 - 1/4 vs 1/4 - 1/3.

Another interesting experiment would be to record the sound of the shot each time and analyze the frequency spectrum in a software like Adobe Audition. I'm sure you'd have a different distribution of frequencies in each case.
