Developed to help designers accurately model the sound level reaching building tenant's ears, the Trane Acoustics Program (TAP) "projects" equipment sound power data through the surroundings (e.g., floors, ductwork, walls), to estimate the sound level that will be heard. Industry-standard calculations published by ASHRAE's 1991 Algorithms for HVAC Acoustics handbook are the basis for this estimate. In TAP, you can model the conditions of an HVAC system by choosing specific equipment and building component criteria. TAP will analyze the sound path and calculate the total effect for the enclosed space.
You can continuously adjust the data and system design criteria to compare the results effortlessly. TAP will even plot presentation quality graphs of NC or RC levels. The Windows-based format means:
- Easy-to-use Windows environment
- Double click functionality
- On-line help documentation
- Professional presentation outputs
When multiple paths are involved (i.e., discharge airborne, duct breakout, return and/or casing-radiated), TAP not only determines the overall sound level at the receiver, but also how much of that sound each path contributes. Customize the descriptions of equipment and building components that generate, attenuate, reduce or regenerate sound. From your input, TAP will accurately model the sound level that will be heard by the building's tenants. Quickly design alternate systems and compare the results on presentation quality graphs. TAP has a built-in graphing function that plots the analysis results on an NC or RC chart.

Strengths
Evaluating the total effect of sound in an enclosed space requires many complex mathematical equations. Solving
those equations manually takes hours of precious design time and is prone to error. TAP streamlines this analysis task with
easy-to-use menus and dialog boxes that help the user create pictorial diagrams of sound paths. As path elements are added,
moved or deleted, TAP dynamically recalculates the resulting sound power levels; and when multiple paths are involved, TAP
not only determines the overall sound level at the receiver, but also how much of that sound each path contributes.
Weaknesses
Requires detailed information on sound paths.
