Bibliography

IEC 60268-4:2014 specifies methods of measurement for the electrical impedance, sensitivity, directional response pattern, dynamic range and external influences of sound system microphones, and also details the characteristics to be specified by the manufacturer. This fifth edition cancels and replaces the fourth edition published in 2010, and constitutes a technical revision. It includes the following changes:
- 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.
