Low　frequency　sound　wave　has　strong　penetrating　force　and　difficult　attenuation　in　the　propagation　process.　A　new　acoustic　black　hole　superstructure　is　investigated.　Multiple　acoustic　black　hole　units　are　embedded　in　an　array　on　a　10　mm　thin　plate.　The　designed　superstructure　of　acoustic　black　hole　is　produced　by　3D　printing　technology,　and　the　acoustic　characteristics　of　the　superstructure　are　verified　by　standing　wave　tube　experiment.　According　to　the　analysis　of　experimental　data,　the　acoustic　black　hole　superstructure　can　achieve　an　average　sound　insulation　of　nearly　30　dB　in　the　frequency　band　of　50-1　600　Hz,　and　an　average　sound　insulation　of　up　to　40　dB　in　the　frequency　band　of　100-600　Hz.　When　the　power　exponent　of　the　geometric　shape　power　function　of　the　acoustic　black　hole　element　changes,　the　sound　insulation　of　the　acoustic　black　hole　superstructure　is　also　discussed.　Because　the　designed　superstructure　of　acoustic　black　hole　requires　high　processing　technology　and　is　not　convenient　in　practical　engineering　application,　a　superstructure　of　acoustic　black　hole　that　is　convenient　for　practical　engineering　application　is　finally　designed　for　experimental　verification,　and　the　influence　of　changed　parameter　on　the　sound　insulation　of　the　structure　is　analyzed.　The　acoustic　superstructure　of　black　holes　has　a　potential　application　foreground　in　aerospace,　automobile　and　naval　ships　which　require　small　size　structures　to　achieve　low-frequency　and　wide-band　noise　reduction.　©　2019,　Editorial　Office　of　Journal　of　Xi＇an　Jiaotong　University.　All　right　reserved.
