Calculation methods used in this program are patterned after the ASHRAE Guide; other ASHRAE Publications and the AHRI
Acoustical Standards. 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
an accurate sound prediction from user supplied input data. If in doubt about the estimation of expected sound levels in a space, an
Acoustical Engineer or a person with sound prediction expertise should be consulted.
