Welcome to the Forum, Mike.

For starters, waterfall graphs are only useful up to about 300 Hz.

Second, the scaling you’re using is making the graphs look either better or worse than things really are (depending on if its SPL, waterfall, etc.) See this post:

Getting Graphs Ready to Post

The deviation from what the post recommends would be for waterfalls. The lower axis should be scaled for the noise floor in your room, which is probably about 35 dB.

Wayne

Wayne,

Sorry for not reading the stickies first. I guess I was so anxious about my graphs looking like that, I ignored to follow standard protocol. I will look over this now and repost with everything in order! Thank you!
