Original text. Later amendments are not shown.

The reference sound is assessed at a single point in one discrete gear, simulating an acceleration condition starting with an entry speed at vaa equal to 50 km/h and assuming an exit speed at vbb equal to 61 km/h. The sound compliance at this point can either be calculated using the results of point 3.2.2 and the specification below or be evaluated by direct measurement using the gear as specified below.
