A very subjective analysis...we have no standard for what loud is for a trad bow, so all are just opinions and are anecdotal at best. Ask the guy with impaired hearing how quiet his bow is?
We could use a loudness meter to truly compare one bow to another for the amount of sound being emitted from the shot. Getting too technical? Likely, but this wasn’t my post. I did a search online for a decibel meter, they start at around $20. Even if you weren’t comparing two bows against each other for “loudness” you could compare just one bow to itself, to find its “sweet spot”, arrived at through tuning. I might consider this, but have always just used my own hearing.
This from Wiki:
A sound level meter or sound meter is an instrument which measures sound pressure level, commonly used in noise pollution studies for the quantification of different kinds of noise, especially for industrial, environmental and aircraft noise. However, the reading from a sound level meter does not correlate well to human-perceived loudness, which is better measured by a loudness meter. The current international standard that specifies sound level meter functionality and performance is the IEC 61672:2003.
