Acoustical Analysis
Solving these algorithms manually can be tedious and time consuming,
especially when one or more paths need further attenuation and the
calculations have to be repeated. Fortunately, computer software tools are
available to spare analysts from the calculation-intensive equations.
Also, computer programs make it easier to perform tradeoff, or “what if?,”
analyses. Examples may include determining the effects of using a duct
silencer, changing the construction of the equipment-room wall, adding
absorptive materials to a ceiling, or placing a barrier wall between an outdoor
sound source and the property lot line.
