Power supplies make sometimes a lot noise in the range of kHz. Is there a regulation for the maximum allowed noise emission for consumer electronics on the European market?
Is there a regulation which would protect customers who buy an alarm clock, but can not sleep anymore, because it chirps loud?
Where can I look up, which sound profile a device for the European market may emit?
So far I found only the German "Technische Anleitung zum Schutz gegen Lärm – TA Lärm" and The Outdoor Noise Directive 2000/14/EC (OND).
