VERIFICATION OF THE DOUBLE LAYER HOLOGRAPHIC ARRAY FOR EXTRACTION OF SOUND FIELDS IN REVERBERANT CONDITIONS

Zdenek Havranek, Ludvik Bejcek
  • Abstract:
    This paper describes methods and presents verification results of improvement of algorithms for visualization of sound fields based on near-field acoustical holography (NAH) by the double layer holografic array (DLA) measurement and iterative technique to remove disturbing sound fields which are not in the examinated area under measurement planes (holograms).
