Abstract

In order to solve the sound source measurement problem in the non-free sound field of reverberation environment, a method of sound field reconstruction was presented. In this method, we took measurement, analysis and reconstruction of the sound source. We chose the anechoic tank and reverberation tank as the experimental environment, the transducer as the simulation object, the hydrophone array as the frontend measurer. By using the single layer hydrophone array, the sound pressure distribution of non-free sound field was measured. Sound wave separation was conducted for the measurement results. The sound pressure distributions before and after the sound wave separation were respectively compared with those in the anechoic tank. At last we calculated the errors of sound field reconstruction. The sound field reconstruction errors were presented when the source frequencies were 5 000 Hz and 7 000 Hz. The results show that this sound wave separation method based on sound pressure measured by the single layer hydrophone array can reconstruct the sound field in reverberation environment accurately.
