Something I don't quite understand is why I'm getting such significantly different measurment result with the different sweep length, I expected these to be similair. I thought it might have had something to do with the impulse time due to room accoustics, so I shortend this but with little effect.

Can someone explain this to me?

Thanks.

Nothing else was touched, just change sweep length. Differences are unexpectedly large.

Thanks Crossrh, I ran both sweeps 2x per measurement. I did notice this before, where the results from a single and multiple sweep where very different, and the latter being much worse.

How would I set "synchronously averaged", sounds intresting.

I'll try single sweeps again tomorrow.
