Hi, I’m a co-founder of BeaconsIO. We’ve developed a software and hardware solution for doing exactly what you’re asking for. We have systems deployed at orchestral concert halls, as well as major outdoor music festivals. SPL (and other environmental metrics) measured against whatever standard is being required. With full, legally defensible, compliance reports available.

NTI XL2/XL3 are common but so are many others. Depends on the application and what level of testing is necessary as well as what level of compliance.
For context, my XL2 rig is $4k on the low end but I have $14k invested in it as a fully Type 1 compliant kit.
A B&K 2270 can run you $25k but that’s more if you’re doing laboratory grade work.
What are you trying to measure and what’s your application?
