The literature deals with three general categories of acoustic measurement: sound pressure level (SPL) measurements, sound intensity (SI)

Unlike the test tires specified in the ISO CPX draft standard, tires used today in OBSI testing seemed to be somewhat arbitrary relative to "typical" tire noise as little data comparing OBSI to statistical passby (SPB) for light vehicles has been reported.

From page 6... ...
Differences between CPX to CPB or SPB relationships have been reported in some European studies. Also, one study suggested that porosity played a role in CPB and OBSI data measured for two test surfaces, one slightly porous and one non-porous (12)
