Warning this is pedantic and unlikely to be appreciated.
I have learned that it is improper to describe transformer turns ratios as decibels (dB). Decibels are mainly used to describe power ratios. Transformers deliver voltage ratios between input and output, but the input and output "power" remain roughly constant (less some small internal losses).
That said it extremely convenient to use decibels when estimating the total gain of a given signal path, but don't try to buy a 10dB or 20dB transformer (they are all 0dB). They will typically be sold based on their numerical turns ratios.
