Claim 6:
7. The method according to claim 3, wherein the electronic device includes at least one loudspeaker configured to generate a signal, at least one microphone configured to capture the generated signal from the loudspeaker, and an Active Noise Cancellation, ANC, circuit or an Active Noise Reduction, ANR, circuit configured to generate a noise cancelation signal, the method further comprising:
measuring a first transfer function value between an external loudspeaker and an additional microphone, wherein the additional microphone is placed inside the reference termination, and wherein the first transfer function value is measured by producing a signal using the external loud speaker and capturing the signal by the additional microphone;
measuring a second transfer function value between the external loudspeaker and the additional microphone, wherein the second transfer function value is measured by reproducing the signal using the external loud speaker and capturing the reproduced signal by the additional microphone; and
calculating a value of a fifth parameter, wherein the value of the fifth parameter is indicative of a damping of the electronic device, based on the first transfer function value and the second transfer function value.
