LOUD!!!

If I could just draw myself that picture would be the perfect representation...  I decided to keep it simple. hehe

The first thing I thought was the layout. A stressed layout can portray loudness.  Other things that can come into play are big UPPERCASE letters, and colors (only thought about it since it is only a sketch)

 These are things that, for me, represent the word LOUD:

A night in the CITY. 80s BOOM box. Police SIRENS. TROMPETS. FIESTAS!

and some other things.
