In Reply to: EMC - Standards for audio interfaces posted by Zehner Andy on 09/23/02 at 10:54 AM:

If you connect loudspeakers, headphones, microphones or taping machines together, not very important with EMC, but if you connect them with "radio" together, when the loudspeaker output power very high, the EMC problems coming, you will get feedback through air, and you will receive your audio noise from some frequency at radio. normally have no any standard limited at your system relation to EMC, (this only I remember).

But your system have another things are very important: you have loudspeaker and microphone working together, you need pay attention for both, because they will get feedback from loudspeaker to microphone very easy.
