While a very significant effort has been made to insure the technical accuracy of this program, it is assumed that the user is knowledgeable in the art of system sound estimation and is aware of the tolerances involved in real world acoustical estimation. This program makes certain assumptions as to the dominant sound sources and sound paths which may not always be appropriate to the real system being estimated. Because of this, no assurances can be offered that this software will always generate Packaged Rooftop Builder 1.39r Page 6 of 13 a Performance Summary For 3T - 13 SEER Project: Untitled1 07/08/2015 Prepared By:Airefco, Inc. 12:45PM an accurate sound prediction from user supplied input data.
