The first one of these I bought didn't register any sound.... I thought I was doing something wrong, but it was a duffer. The second one worked immediately... I tested it by blowing gently into the "sensor" whilst looking at the needle.

Anyway, I calibrated my home cinema as follows....

1. On AV amp, set all speaker channel levels to "+/- 0db"
2. Set SPL meter to C-Slow
3. Set SPL meter to 80db sensitivity (this means that when the sound it receives is 80db, the needle will sit on 0db - i.e. there is 0db deviation from the 80db)
4. Send the test tone on AV amp to the front speakers, turn the volume up until the SPL meter shows 0db (i.e. the test tone was playing at exactly 80db).
5. Send test tone to each surround speaker in turn, including the sub, adjusting the channel level on the AV amp for each until all channels registered as 0db on the SPL meter.
6. Once done, it is worth doing a repeat check to make sure they're all set ok.

That's it!

It sounds long-winded/complicated, but it really is straightforward.

People with modern fancy pants AV amps might rely on the built in calibration, but for people with older systems, this really is a cheap an effective method. If your AV amp doesn't have a test tone facility, some calibration DVDs have one on them.

Many positive reviews, so I thought I should balance them with my not so positive experience.

Mine arrived with a fault when using the 60db range (the needle was always deflected), which admittedly reduced my confidence with it.

I was also disappointed that the lower limit was 50db (or 60db in my case!), it is actually quite useful to have the low end values around 30db (even if the calibration might be a little dubious at these levels).

Whilst it is good to have the A/C weighting switch you should consider if it is really necessary. Unless you are intending to do some measurements with explosive or impacting events C weighting is not so important. For audio and noise nuisance issues A weighting is all you need.

For home users a high degree of calibration, whilst a consideration, might not be so vital. If you are using it to balance speakers, or comparing noises - remember you are comparing values from the same unit. For Noise nuisance problems obviously calibration matters more - but again officials are likely to want to use their own (very expensive) kit.

I replaced my faulty one, with a £20 CEM DT-85A. It will do for me, it has fixed A weighting and is digital, but the averaging is not a good as offered by the Silverline above.

I'm not sure if this is exactly the same as the eponomous radio shack version, but it seems to be!

I used it to set up my home cinema accurately. The best thing is to use it to figure out your sub/sat crossover frequency correctly using this, and also to parametrically tune your sub so you get a flat smooth response all the way down. It will sound a lot lot better than any automatic system.

Oh and my one came with a new battery included despite it saying in the description above that it's not included. It was inside the unit (philips screwdriver needed to open). Just pointing out so it will save you a couple of pounds aaginst the already low price

If you are looking for a simple, cheap and effective sound meter to tune up a home cinema system then look no further. It is not a highly specified detailed product but then you have to match that against its use. The controls are easy to read and use and the analogue meter is just fine. If you are using it for a home cinema setup just remember that dB scales are log scales and the meter is therefore not a linear one, also make sure you use the right weighting between A and C. Look it up on wikipedia for an explanation but essentially use slow response, C weighting and a baseline tone of 70 dB ish. Try to set your reference tone to read 0 on the scale at the required range and then match the other speakers to this one. I used the centre just for convenience. Don't expect to be able to tune the speakers with a huge amount of fidelity and expect the needle to move around, this is normal just watch it for a while and estimate the mean SPL. This meter does not have the sophisticated multi frequency weightings in it, it is purely the simple ones so if your amp does more complex things, you may have to tune up over several frequencies.

Basically for a pretty good setup then this is cheap, usable and effective.

Set up my two home cinema subwoofers with this sound level meter. Merely buying a great subwoofer is no guarantee that you'll wind up with great bass. There are too many ways to squander its performance potential, and that's why putting in the extra effort to achieve proper subwoofer setup is crucial.

A sound level meter can be a big help when setting speaker levels, but it's nearly useless for determining the sub's correct volume level. The "by ear" method works well enough. I can set the sub's volume level with DVDs in 10 minutes or less, but with CDs I might be fiddling around for days. Again, if you feel like this is all a little too complicated, relax, take a deep breath, run the auto setup program, and let the receiver sort things out.

Set the SPL Meter to C weight, Slow Response, 70 range (-60 to 76dB on scale).

SPL Meter to be placed at head height in primary listening position, 45degrees from vertical, towards speaker.

Then on one of the speakers (e.g. front right), I will start pink noise from that speaker only, turn up amp volume until 75dB reading on SPL Meter from that speaker.

Then go to each of the other 4 speakers, make adjustments to amp (not volume but the dB balance settings) so that all reading ~75dB at primary listening position.
