In a typical piezo (noise maker) transducer, will a series R knock
down the amplitude?

I love to cook with wine. Sometimes I even put it in the food.

Suppose so, when it's driven by some voltage source anyway. The energy
dissipated by the resistor will not be transduced into noise.

It couldn't generate any sound unless its input impedance has a
resisitive component--it would violate conservation of energy. (And
even a pure capacitor would see a decrease in voltage swing if a series
resistance were added.)
