- clarification of Table 5 of classification of characteristics;
- clarification of graphical representation;
- clarification of environmental influences;
- rewritten clause for EMC;
- tolerances and more specific values for noise measurements;
- inclusion of near-field response for sound source-to-microphone distances of the order of 30 cm.
