Sound level meter data Logger

[UTcaveman]

I need to do some sound level testing. I know there is off the shelf data loggers for sound level metering. The price isn’t bad I’m mainly wonder if I could sent up the same kind equipment with off the shelf data logger and microphone?

No you couldn't. At least not easily.

The signal processing and calibration is non-trivial.

Given that the standards are published, and any weighting can be performed digitally, I wouldn't be quite that negative. It does rather depend on what you are trying to achieve.

It totally depends on what you are trying to do. For one thing you won't have good accuracy compared to a dedicated device. Higher end systems will also have built in analysis like FFT. I bought some general mics from B&K several years ago and they were $4000 each, but they are made for testing and have an almost linear response across a broad frequency range.

In short, if there is money on the line I won't trust it. If you only need it for a short while it would be best to rent one, and it should come with a calibrator.
