  Fake dBA meter value expression

  Posted by Dax Castro on May 31, 2017 at 6:30 pm

  I am creating an animation that illustrates the noise level of specific situations (conversation, car passing, train passing, jet engine, rock concert). I have the meter all set and have applied a wiggle to the rotation of the meter so it looks realistic.

  

  My problem is that I would like to have numbers below it showing the values as well. I dont need to have the numbers tied to the needle position or anything too complicated. I am thinking of just animating the dBA value separately.

  Here is how I am thinking it would work. (of course process, not actual code)

  1. tell it what number to start with, then what number to end on and how much to wiggle that number.

  Start at 12 and increase to 16 across 4 seconds. Then wiggle +/- 2 of the end number

  ====

  Start number = 12
  End number = 16
  duration = 4 (seconds)
  wiggle = -2,2

  Any help is SUPER appreciated. I did look at several other threads but nothing seemed adaptable to my situation.
