Performance Summary For 27T <br />Project: Climatec Energy - City of San Leandro 01/15/2016 <br />Prepared By: 0254PM <br />Calculation methods used in this program are patterned afterthe ASHRAE Guide. otherASHRAE Publications and the AHRI <br />Acoustical Standards. While a very significant effort has been made to insure the technical accuracy of this program, it is assumed <br />thatthe user is knowledgeable in the art of system sound estimation and is aware of the tolerances involved in real world acoustical <br />estimation. This program makes certain assumptions as to the dominant sound sources and sound paths which may not always be <br />appropriate to the real system being estimated. Because of this, no assurances can be offered that this software will always generate <br />an accurate sound prediction from user supplied input data. If in doubt about the estimation of expected sound levels in a space, an <br />Acoustical Engineer or a person with sound prediction expertise should be consulted. <br />Advanced Acoustics <br />Advanced Accoustics Parameters <br />1.
