This is an orginal 24 pdr Howizter firing bar shot. If you look closely you can see it in the air.

In this shot the Howizter is firing grape shot which you can see in the air. It seemed to maintain a pretty good pattern. Each of the nine balls are 2.6 inches.

I am not sure I understand your question. They put out a DVD that has recordings of artillery projectiles in flight using different microphones at different distances. One of the problems they had in recording the sounds was that they were very brief. We reduced some powder charges to reduce the velocity and increase the amount of time to record the sounds. In the movie you will hear the ring of the barrel of this 24 pdr once during a boardside. You will notice that we wrapped carpet around the barrel in an attempt to eleminate the ring. We didn't have that problem with the iron Napoleon.

I thought maybe it was a photo of the sound work for "Master and commander"

Yes it is. They really liked the snow as it provided for better sound recording. The main problem was that it seemed like everytime we got set to record you could hear snowmobiles coming or going. It is amazing just how far that kind of sound carries. Another problem was that we blew out a couple of the microphones because the sound was too intense.

I measure the frequencies of sounds related to the rpms of the motors we build as a part of final testing (this type of testing is usually done as a method of determining wear and bearing defects at the other end of the life of the motor).

It is VERY difficult to get a place away from sounds of other sources. We had to build a 'sound proof room' - I call it the padded cell.

The general rule of thumb in industry is to get away from it, it takes so much to isolate an area free from it.
