A method in a communication device for suppressing noise of a first signal, captured via a primary microphone, arranged on the communication device such that it is capable of capturing noise and intermittent speech, the noise suppression being executed by processing signal power spectrum estimates of the first signal and a second signal, captured via a reference microphone arranged on the communication device, such that it is capable of capturing noise at substantially the same signal level as the primary microphone and speech at a lower signal level than the primary microphone, the method comprising: - determining, on the basis of the difference between the signal power spectrum of the first signal for a respective time frame and its long term average value, whether the first signal comprises non-stationary signal components or substantially stationary noise; - determining, on the basis of a ratio between a dynamically adapted inter-microphone gain offset and a power spectrum ratio of the first and second signals, whether the first signal comprises near-field signal components or substantially far-field noise, in case it was determined that the first signal comprises non-stationary signal components, or updating the inter-microphone gain offset based on the power spectrum ratio of the first and second signals, in case it was determined that the first signal comprises substantially stationary noise; - updating a noise power spectrum estimate of the first signal with a stationary noise power spectrum estimate if the first signal is considered to comprise substantially stationary noise, or with a far-field noise power spectrum estimate if the first signal is considered to comprise substantially far-field noise; - computing a frequency response of a noise suppressing filter on the basis of the estimated noise power spectrum, and - suppressing noise from the first signal by applying said frequency response on said first signal. - determining, on the basis of the difference between the signal power spectrum of the first signal for a respective time frame and its long term average value, whether the first signal comprises non-stationary signal components or substantially stationary noise; - determining, on the basis of a ratio between a dynamically adapted inter-microphone gain offset and a power spectrum ratio of the first and second signals, whether the first signal comprises near-field signal components or substantially far-field noise, in case it was determined that the first signal comprises non-stationary signal components, or updating the inter-microphone gain offset based on the power spectrum ratio of the first and second signals, in case it was determined that the first signal comprises substantially stationary noise; - updating a noise power spectrum estimate of the first signal with a stationary noise power spectrum estimate if the first signal is considered to comprise substantially stationary noise, or with a far-field noise power spectrum estimate if the first signal is considered to comprise substantially far-field noise; - computing a frequency response of a noise suppressing filter on the basis of the estimated noise power spectrum, and - suppressing noise from the first signal by applying said frequency response on said first signal.
