I found this interesting, thought I would share:
"Acoustic scientists at NYU have recently started to quantify that information by mapping the sound that radiates from a piano. Picture a seven-foot grand piano in a studio. The lid’s missing, so you can see all the strings. Researchers suspend a rod embedded with 32 microphones over the piano’s body...."
"They’d record the piano in one spot. Then move the microphones eight inches. Record the note. Move the mics again. Record the note. Over and over and over, until they reach the back of the piano. At the end, they get “what is basically a very dense acoustical scan of the radiation pattern of the grand piano,” Roginska says...."
