[PD] Relative Db measurement

[Chris McCormick]

Hi,

Hopefully this elementary audio question is not too stupid.

If I have some signal source how I can I measure the relative change in 
Db when some change is made to the signal? E.g. if I have an [osc~ 440] 
going into a [*~] and I change the multiplier, how can I measure the 
output from that and determine relative change in Db when I change the 
multiple?

Also does this even make sense on Db scale?

Thank you!

Cheers,

Chris.
