The use of acoustic holography in the high-frequency $p$-mode spectrum canresolve the source distributions of enhanced acoustic emissions within halostructures surrounding active regions. In doing so, statistical methods canthen be applied to ascertain relationships with the magnetic field. This is thefocus of this study. The mechanism responsible for the detected enhancement ofacoustic sources around solar active regions has not yet been explained.Furthermore the relationship between the magnetic field and enhanced acousticemission has not yet been comprehensively examined. We have used vectormagnetograms from the \Helioseismic and Magnetic Imager (HMI) on-board theSolar Dynamics Observatory (SDO) to image the magnetic-field properties in thehalo. We have studied the acoustic morphology of an active region, with acomplex halo and "glories," and we have linked some acoustic properties to themagnetic-field configuration. In particular, we find that acoustic sources aresignificantly enhanced in regions of intermediate field strength withinclinations no different from the distributions found in the quiet Sun.Additionally we have identified a transition region between the active regionand the halo, in which the acoustic source power is hindered by inclined fieldsof intermediate field strength. Finally, we have compared the results ofacoustic emission maps, calculated from holography, and the commonly used localacoustic maps, finding that the two types of maps have similar properties withrespect to the magnetic field but lack spatial correlation when examining thehighest-powered regions.
