Hi All,

A few naive HOA Qs I'm hoping to gain some insight on...


1) Order (M) is related to minimum number of loudspeakers by:

        (M + 1)^2      for 3D
        2M + 1           for 2D

Is there a similar relationship for order and loudspeaker array radius?

The practical question comes down to, does my room (or installation) size end up limiting the order I can successfully synthesise? As an example, if I'd like to try 5th order, do I need to make sure my room is at least minimum size? (Yeah, there are problems regarding loudspeaker positioning, etc., but let's disregard that for now.)


2) And a related question.... For HOA do I prefer a narrow dispersion loudspeaker over a wide dispersion loudspeaker?



Thanks for your advice in advance!!



My best,
J Anderson
