Noise emissions (dB) in units in openlca?

Question

I need to create flows having units noise emissions like dB but I cannot find them as units in ecoinvent 3.12. Do I have to create it? While noise is measured in dB (logarithmic), what will happen when running calculations with LCI units. Do I need to convert dB data into other units(energy units) some how?

Answer 1

Hi, interesting question, I would not convert decibel to other energy units but add it, it also needs a different unit group (and flow property).

In our MSDB database, we have even two, dB and dB(A):
