Ballroom Music Spillover into a Beluga Whale Aquarium Exhibit

Figure 7

Measured (circles) and modeled (diamonds) SPL in a 1/3 octave band in the aquarium for given music in the ballroom with a SPL of 100 dBA at frequencies 215, 1000, 5000, 10000, and 14000 Hz. Full FEM modeling was carried out for two lowest frequencies (215 Hz and 1000 Hz). The FEM results (asterisks) compare well with the measured values and plane wave modeling. The dashed lines are linear fits to the data/model in two frequency bands.
