- Calculation of noise reduction and acoustic impedance of the duct system is needed for the one-port source model, which is widely used in the field of duct acoustics for extracting the source characteristics and predicting the radiating noise at the open end.
- The program provides you with a complete eight-octave band acoustical analysis. It takes into account natural attenuation of duct and fittings, sound power splits, end reflection, insertion loss of insulated duct and fittings and the critical space/room attenuation.

In 1986, ACCA (Air Conditioning Contractors of America) released their Manual J [ANSI/ACCA 2 Manual J - 2016] load calculation format for residential HVAC applications. It was a success that started a trend for future standard calculation and design manuals. There is a Manual D [ANSI/ACCA 1 Manual D - 2016] for residential duct design. Manual N for commercial load calculations and Manual Q for commercial duct design (low velocity and low pressure design). For air and hydronic balancing and testing there is a Manual B. A Manual Zr [ANSI/ACCA 11 Manual ZR - 2020] for residential zoning systems. A Manual T for air distribution fundamentals. For residential equipment selection use Manual S [ANSI/ACCA 3 Manual S - 2014]. This is different from a Manual RS which covers special design steps and principles to install residential HVAC systems for today's homeowner. Commercial systems selection would be Manual CS. There is a Manual H for heat pump systems. Block story pc. A Manual P for psychrometrics (relative humidity and moisture). There is one for HVAC design for swimming pools and spas: Manual SPS Rauland 2524 master clock manual. [ANSI/ACCA 10 Manual SPS - 2011 (RA 2017)]. Many manuals are compliant with American National Standards Institute (ANSI) standards and national building codes. ACCA produces other quality books and design materials. They are a great asset to the HVACR industry and their website can be found here.
