An audio system includes an input node for receiving an audio input signal, a signal processor coupled to the input node to receive the audio input signal, and an output node for providing an audio output signal to a speaker. The audio system includes a first fuzzy logic controller configured to receive sampled signals related to the audio input signal and a gain of the signal processor, the first fuzzy logic controller configured to determine a risk level of the audio output signal. The audio system also includes a second fuzzy logic controller configured to receive feedback signals related to the audio output signal and to determine a correction factor. Further, the audio system is configured to determine a control signal based on the risk level and the correction factor, and to adjust the audio output signal based on the control signal.
