Stage Research

The Sound Template, developed by sound designer Shannon Slaton and available from Stage Research, features specs and sizes of more than 40 of the most widely used theatrical speakers from manufacturers including Meyer Sound, d&b, Apogee, and EAW. This ½"-scale template includes audio symbols, specs, and measurements, as well as all steps and formulas for placing speakers. Users can draw a speaker; use pattern angle and compass holes to draw the sound field; use speaker specs — dB loss and watts to dB — to predict SPL at a certain distance from a speaker; add delay speakers; use distance to predict delay; and predict combined SPLs.
