Yes. Layered cookware can produce different sounds under induction, so the pan and power setting are relevant observations.
What the observation means
A familiar low buzz differs from a new harsh sound, damaged pan or electrical crackling. The manual may describe normal operating noises, but it cannot excuse every change.
A useful next step
Record whether the sound follows one compatible pan or occurs across suitable cookware. Do not heat empty pans to compare noise. Stop use for smoke, damage or electrical warning signs, and avoid treating sound alone as a definite diagnosis of the hob's electronics.
Manuals and supporting guidance
Model-specific instructions take priority. These references support the practical principles discussed here; they do not diagnose your appliance.
