Cutting to the chase, my TAC-15i when fired is measuring 99 decibels at 1 meter, outside. However, I need to find a place where I can safely test the TAC-15 inside to eliminate outside ambient noises. Or perhaps test the TAC-15i in the environment of issue, a quite forest at 1 meter, 32 meters, 64 meters.
For what it is worth I did eliminate the Hammer striking the hammer stop pin from the tests by using 14lb fishing line to pull on the catch that hammer normally would hit.
In future testing I would like to see where most of that 99 decibels is coming from. The limbs, the string, string hitting the stops, etc., and then see if there is way to reduce the noise.
