Early energy ratios

These parameters are defined in the Calculate->ISO 3382 section.

The early limits can be changed to numbers other than recommended in the standard. For Clarity, it is also possible to get two values as output of the calculation if two numbers are typed, separated by a ‘&’. For example, ‘50&80’, which is the default setting, gives the two clarity values C50 and C80 as output. Note that this applies when writing parameters to grid or text file. When using the Room Ac. Parameters plot type, only one parameter is plotted, and the lowest early time is used, in this example C50.
