Directly next to it (30cm), I measured an average of 69dB (with a short peak of 73.5dB) during the entire boiling process of 1.6l of water, which corresponds to the volume of a normal conversation. But if you take into account the current guidelines of the BAG and keep a safe distance of 2m, the average is still 62dB. For me, therefore, a 5 on a scale of 1 to 10.
