    Hi all, I'm an Architecture student trying to design a project for music practice rooms which people can look into and hear some sounds coming from the musician inside, but can't disturb the musician (i.e. little sound travels into the room), and I found out that a sonic crystal could do just that.

    Armed only with knowledge of pre-University level Physics, I've been trawling the Web for quite some time, and I've been unable to find instances of sonic crystals which block a sizable band of audible frequencies.

    (My exploration started here: )

    Could anyone enlighten what sort of material would be suitable for a columnar sonic crystal that could block out a good amount of everyday outdoor sounds? And dimensions of the column, spacing between columns, total depth of sonic crystal...

    Any help would be really appreciated. Thanks!
