Can anyone provide a simple formula whereby I can calculate the
acoustic resonance of a physical object if its length is given in mm?

Thank you,

No...The resonance of a physical object is not a simple function of the
length. Resonance involves the length, width, general size and shape, mass
and modulus of elasticity. It also involves temperature and the specifics of
how it is held or constrained. Furthermore in most objects, there are many
modes of vibration so that no one simple frequency occurs. Such is the case
with bells, for example, the multiple modes causing richness in tone.
However, there are simple equations for well defined objects like steel rods
held at the specific ways or wires under tension. If you ask a specific
question about a specific object, maybe we can find an equation.
