@tonywinga, there has not been a Bureau of Standards for almost 35 years. Bringing this up shows you don’t have any experience in calibration or measurements which is likely why you were "abused". Other than absolute gain, what exactly do you think a NIST traceable calibration would be on an audio tester? A large portion of the test gear for what I do is not NIST traceable for calibration. Why? NIST does not have any standard remotely applicable. It’s fine for basic things like current, voltage, weight, thickness, etc. but not for complex measurements that either don’t have a standard or are defined by other technical bodies.
This is why I don’t post often in audio forums. Conversations just end up as pages of whining because 1/2 the world does not believe what I believe and I am offended that they will not stop. What is worse, people will make things up to support their argument.
Take this piece below. This is so factually incorrect that I wonder if the author even visited the site? I don’t go to ASR often either, as most of their threads end up as technical fights about things I don't care about, but when I was planning my room, I asked a lot of acoustic questions there and I can state without reserve, that most there would never discount acoustics and would abuse you if you said acoustics did not matter.
Their common point is a total ignborance of acoustic condition because they need electrical tools they dont need to tune a room... All rooms are equal for their activities....
I said it pages ago, this will be just whining until one side proves to the other they are right, but I am beginning to think people would prefer to whine instead of trying to reach a conclusion. Even if either side conclusively proved the other wrong, I am not sure they would accept the outcome.
