"Physical Dimension" DB
Posted: Wed Mar 21, 2012 8:41 am
Dear colleagues,
I found an issue with the physical dimensions. In the database we have defined:
DB ; Decibel; Schalldruck with the default physical unit dB.
Actually Decibel is a physical unit as far as I understood. So it can't be a physical dimension itself. Regarding noise the dB unit is used for the "noise level" or better the "noise pressure level". The German translation is "Schalldruckpegel".
I we intend to have this entry for the noise pressure level the abbreviation DB might not be a good one.
We should discuss this at least in the next meeting. My proposal is, if noise level should be addressed with this entry:
change DB to NL and use "Noise Level" / "Schalldruckpegel" as name.
On the other hand there is already an entry for this in the database:
SP; Peak Sound Pressure Level; Schalldruckpegel
So the above entry might be defined for a different PD or is mistaken/obsolete?
Bye,
Dirk
