I would have thought that one of the clever folk here would have mentioned to get a rechargeable 9v battery. The do make them in 9v these days and if you are using that many batteries, they are a very good alternative.

Indeed you did but everyone else wanted to talk about other things.......
The question was, "How much do you spend on your SPL db metre?"
That's all I've been talking about. What I, and some others spend goes way beyond batteries. But you asked the question.
Yes in powering it! I mean its not much good without batteries, is it now.
Maybe I should buy some Eveready 9volt batteries I hear they’ve got ever lasting power.
It even has a tiny picture of cat on it.
I got it! They make those wind-up radios and even touches! Why not a wind-up SPL db metre? That way you don’t have to keep spending money on batteries. Just a thought.
I have two containers full of batteries for later disposal when I take them down to a shop. You know what they, should do! If you hand in 10 or more batteries they should give you x2 free batteries of your choice.
I know I can daisy chain series the 9volt batteries together to get my last full 9volts from 10 or more batteries. Waste not, want not.
Yes, it's still a toy regardless of how much you pay.
And 230 pounds is nothing for a noise meter. Follow the link to the Larson Davis Model 720. This is the Volkswagon (entry level) of sound level meters and will set you back about $3,000 (or more). You'll also need the calibrator so plan andother $800-$1,000.

What makes it a tool rather than a toy is it's purpose and use..., not its cost.
My HT system, Corvettes, and garden railroad are also toys based on their purpose and use. Doesn't matter what they cost.
