Measured monopole and dipole room responses

[sendler]

Why do you think all of the charts become suddenly clean above 1k? Is it the woofers cone diameter getting directional? A limitation in the measurement scheme? Or, just that all of the important differences between dipole and monopole are over with above that frequency?

Diyaudio is back, nice

I think you are lacking a definition of transient.

Anyway who cares about decay since the attack may be much more important!

The thing is with real music like signals the room may never reach the steady state condition. Thus using steady state method of measurement is a poor choice.

The bursts will capture the transient behaviour, attack and release, of the room.

Never forget that when humans are included in analysis there allways will be number of subjects that shows the results which will not fit inside the confidence limit of the distribution of the results. Training is one of the most significant factors to make a difference, for example.

And hearing the envelope is not the same thing as a transient. From all that I know what we sense at LF is a steady state sound. There were studies of "modal decay" in the AES which showed that people did not hear these decays. They heard the integrated sound level, i.e. a more steady state sound.

Hello,

Yes and Yes! This was excatly my starting point to do these tests. Because I can A/B/C switch monopole/dipole/dipole line array with digital cross over by a single button press right here right now, and I can hear big differences between them! Then, I started finding out the reasons behind it all. Now, I think I'm at the right track because I think the big difference can be found in the time domain!
