So, what you plan to do does make a great deal of difference in the decision you make. Though, assuming the size is not a problem, for under $100, the Software and USB microphone combined with a Laptop computer, are a tremendously powerful tool that will do any of the things I suggested and more. Plus, not only can you test your own system and room, but, assuming you have a Laptop, it would not be that hard to test the systems and rooms of your friends. The amplification and frequency response correction is done farther down the line.
For example, the 84-dB SPL calibration level that you used with the Avia test DVD is termed "quite loud" by most listeners. The best way to find the best spl meter for home theater is to do research. You can read reviews, compare prices and decide which product suits your needs. In today's day and age, the best spl meter for home theater is not always the cheapest. Many of us are finding that buying a superior quality product with a warranty is usually worth it in the long run. VERSATILE – A great basic sound meter for use across the spectrum in many different fields from music recording, neighbor noise complaints, industrial settings, office settings, speech therapy & more.

I’m curious if you have any recommendations for android – with the exception of Decibel X, which you did not go into – the tools you reference above only seem to be for iOS.
The C weighted simulates the frequency properties of high-intensity noises of the human ear, which are suitable for the sound pressure analysis of machine motors and machines. More professional measurement methods provide users with a more perfect user experience. 【Digital LCD Display 】 The digital display is a 4-digit LCD display with a resolution of 0.1 dB. Large backlit LCD digital display, the reading effect is clearer in dark places. When the battery is low, the LCD display will display a low voltage icon, indicating that the power is low at this point and the battery needs to be replaced.
WTF is Surround Sound?
To make the best purchase possible, buyers need to know which factors are most important in determining how well a product will work for them. If you simply want Relative Measurements, meaning the actual number is not as important as the difference between two measurements, then the very low cost Smart Phone Apps would be a good choice. Then there is the matter of portability, naturally an SPL Meter or a Smart Phone are far more portable and less complex than a Laptop and accessories. If you simply want to take a couple of general Loudness measurements, a simply SPL meter is all you need. The the SPL meter should turn off after a period of non-use.
Now the very same SPL meter that’s in our TestCard ProHD app is available separately. I've been using REW & a UMIK-1 myself, not sure how accurate it is compared to an actual spl meter, but it seems to work fine to me. There are SPL Meter Apps that you can get for a Smart Phone, though I'm not sure how you calibrate them, but they cost about $1. They might be good for making relative measurement, but again, not sure how accurate they are. SPL meters are designed to measure Sound Pressure Level . Ime many “bad” reviews are from people who don’t know what they are doing.

It was very easy to run down the batteries on the analog Radio Shack meter since it didn't have this feature. Make sure you get one that is from 32hz-8khz if using pink noise for test signals which is what many receivers use. Obviously the more accurate the better, some are +/- 2db and some are better than that.
The THX promo clip measured 85 dB SPL, while average movie sound levels were between 70 dB and 78 dB–comfortable and not too loud. Coming attractions previews, however, were louder, peaking at 90 dB SPL, a lot louder than the actual movie presentations. Some systems will have 5 speakers and some will also have the LFE, or bass effects, speaker to give the “0.1” to make 5.1 audio. With the SPL meter there are 7 main speakers shown with one LFE to make 7.1. With a 5.1 system the Mid speakers will not be present and therefore can be skipped.

FEATURES – Automatic backlit display for easy visibility in dark situations. MAX/MIN hold feature for measuring absolute high/low peaks. +/- 1.5dBA with 0.1dBA resolution & measuring range of dBA. Up to 30 hours of continuous use on a single 9V battery.
The fact is, for 99% of the users here, ANY of the cheap SPL meters are fine. About the Mics on the Phone, i would imagine that there accuracy would get thrown off over time with say lint build up or other gunk that gets clogged in it. I also use Audio Tool for the iPhone however I don't have anything to compare it to. I only use it when I want to see just how loud I'm playing my movies.
A red needle is provided for peak noise level information and is not required during calibration. If I were to have only one SPL app on my phone or physical meter, I would go with Decibel Ultra. Because even the freebie version has all the essential information you need from an SPL meter. Not only does it have two simultaneous readings – A-weighted and LC peak, but also a bar-graph level and frequency display to show which frequencies are dominant. Much to my surprise both the B&K and the Aperion gave me readings within 0.4 dB of each other, which is pretty good. Regarding absolute vs. relative measurements, nearly all measurements are relative to something else in their traceability chain to a National Measurement Office .
I tried one a while back, but now I can't remember the name. It had an RTA display, and peak hold capability, but was really slow to sample and update readings. If we had an accurate source, and established reference levels on our phone apps, I'm not sure the mics would hold any degree of accuracy over time.
The third one is called sound meter and looks like a speedometer but also doesn't hold peak. The best spl meter for home theater will last longer than other products. Because the materials are of better quality, they are built to withstand more wear and tear or better cared for over time.

Large easy to read backlit display with a MAX/MIN function to know the MAX and MIN dB levels recorded by the meter. If you are trying to plot frequency response, while I have done it with an SPL meter, the frequency range is somewhat limited. Plotted the low end of my speakers by taking readings and putting them into a spreadsheet, and plotting them as graphs. But, the spreadsheet I have does not allow for a logarithmic plotting on the X-axis.
