Figure 8: Experiment results of TRESM, IWESM, SDIESM and RWAH algorithms for dual sources.
From: A refined wideband acoustical holography based on equivalent source method
(a,b and c) are the reconstruction results of TRESM at the frequency of 500 Hz, 2000 Hz and 4000 Hz, respectively. (d,e and f) are the reconstruction results of IWESM at the frequency of 500 Hz, 2000 Hz and 4000 Hz, respectively. (g,h and i) are the reconstruction results of SDIESM at the frequency of 500 Hz, 2000 Hz and 4000 Hz, respectively. (j,k and l) are the reconstruction results of RWAH at the frequency of 500 Hz, 2000 Hz and 4000 Hz, respectively. (m,n and o) are the microphone measurement sound pressure level (unit: dB) of the frequency of 500 Hz, 2000 Hz and 4000 Hz, respectively.
