Abstract:
An interactive Windows-based computer program has been developed that can be used to conduct complete acoustical analyses of HVAC systems. The program can be used to track sound from a HVAC sound source such as a fan to a room. Both sound from a single path between a sound source and room or from multiple paths between a sound source and room can be investigated. The program has a full set of editing features that include change, delete, and insert options which allow an individual to interactively design an HVAC system to meet specified acoustic design criteria. Design templates for systems in which multiple acoustical analyses will be conducted can be developed and stored to minimize the time associated with inputting data to the program. The program has options for printing out tabulated results and noise criteria and room criterion curves for inclusion in reports.
