High output in a whistle can be achieved on air at anywhere from 15 PSI on up to 300 PSI. The output depends on the scale and the operating pressure depends on...

A clue to what you are experiencing is that you are comparing your 4" whistle against what is most likely a 6" whistle. Even if they were equally loud, you...
Ricahrd, ?? So what your saying here is that if I had 4" hooter at 2:1 scale and a 6" hooter at 2:1 scale, the 6" would be slightly louder even though they are...
Exactly, but not by much. ... and a 6" hooter at 2:1 scale, the 6" would be slightly louder even though they are both 2:1 scale? ... 4" ... scale ... at ... 1"...
Richard,? ???Two more questions: 1. What's the best setting for db readings? The only place I have to do this is my place of work ( auto shop ) which is in...
You won't get accurate SPL readings indoors unless the walls, ceiling and floor are sound absorbing as in an anechoic room. In a typical indoor reverberant...
Referring to message #3561 I meant that no matter what your whistle design or scale, the operating pressure is inversely related to the slit width. This is...
In answer to this question, it depends on the output of the source and the distance between it and the point of measurement. For a typcical locomotive whistle...

My whistle supply is outside the building but I'm only able to get the whistle 3 feet from the building. The building itsel is the only obstruction all other...
Thanks for clearing this up. I know that the few whistles I've built following yours and David's advice have been excellent. So far all I've built have been 2...
Forgive me for my ignorance, but what do you mean by flat "C" weighted? I'm new to SPL meters so my knowledge of them and how to properly use them is nill....
On sound level meters there is a setting called "weighting". On most meters you have a choice of an "A" weighting, which rolls off frequencies below 500 Hz,...
Jamie, We would really like to see and hear the fruits of your efforts. This should get you started. If you have a digital camera, you can upload the pictures...
In this case, take your measurements from 90 degrees off to the side, where the wall of the building will have minimal influence on the reflected sound. Most...
