It is possible to define dB as a unit, simply define it as:
since dB is in essence unitless. This is what happens upon use:
There's no way to know that 1 means dB, as it could also be an angle { sin(1) }, or any ratio.
But you can put dB in the placeholder for the unit at the result, to get:
Drawback is that you have to do that for every result.
Success!

dB := 1 - OK
dB+dB=2 It is not OK
The decibel (symbol: dB) is a relative unit of measurement equal to one tenth of a bel (B). It expresses the ratio of two values of...
Decibels were invented to simplify manual calculations, calculations on a logarithmic ruler. In calculations with the help of Mathcad or SMat, they are not needed at all!
There is dB in SMath, But what to do with this "unit", no one knows.
My colleague, a leading expert in the world on the problem of noise suppression at industrial facilities, believes that it is necessary to redo all calculations where decibels are used to conduct its on a computer.
