Unit of Sensitivity Plot for IMP23ABSU

[TomRett]

What is the actual unit (dBV, dBSPL etc.) for the plot? dB is not relative to Volt or anything.

Hi @TomRett ,

You are right, the plot is in dB.

The graph is normalized with respect to the sensitivity at 1kHz. If you want to get the dBV you need to consider that the sensitivity at 1kHz is -38dBV, and therefore add this value to that graph.

Thanks! Can you provide the data of the plot (e.g. sensitivity- and frequency-array)? Otherwise i would have to write each value manually into each array which is not precise enough.

Furthermore, if i convert the dBV back to V i actually get Vrms at each frequency, am i right?

Hi @TomRett ,

if i convert the dBV back to V i actually get Vrms at each frequency, am i right? Yes. it's correct.

Can you provide the data of the plot (e.g. sensitivity- and frequency-array)? Unfortunately, we don't provide the raw data.
