[QUOTE="Ivan Beaver, post: 75811, member: 30"] Re: Danley SM80 and others shootout Monday January 14 at Danley in Gainesville, GA. An SPL meter can be used for a variety of different things. Some times it is important to be accurate-and then others times it really doesn't matter. Such as what we were doing during the demo. When we were setting levels-it didn't matter what the numbers said-as long as they were all the same (or very close anyway). We just turned the noise up to a level that was comfortable and louder than the background noise-chose a easy to remember number and set all to that. Other times it is about relative differences. So I would also ask the question-"How many people have actually had the apps/mics CALIBRATED?" How do you know what the meter is telling you is correct? Yes the accuracy starts to fall apart when the levels get high-but what is 'high'? I assume there have been some studies-I am just not aware of any. Yes the "apps" can be quite handy-but are you willing to testify in court using the numbers they provide? I was at a sub demo a couple of years ago and we had a good variety of different SPL meters-different models and some of the same models. So we did a quick test and found they all fell within about a 10dB range. TEN dB! That is quite a bit. And if somebody is telling another that their system can do XdB-they could be waaayyy off. Just try to get another 10dB out of your system and see what happens. [/QUOTE]
