1. A physiological monitoring device, comprising:

  • an acoustic transducer;

    a processor communicatively coupled with the acoustic transducer; and

    an output interface communicatively coupled with the processor, wherein a physiological signal detected by the acoustic transducer is transmitted to the processor, and wherein under control of the processor the device segments the physiological signal, in an estimation period for a physiological parameter, into initial time windows, identifies one or more noisy time windows among the initial time windows, replaces the noisy time windows with replacement time windows having a baseline amplitude, calculates an estimate of the physiological parameter using amplitudes of the physiological signal in non-replaced initial time windows and the replacement time windows, and transmits the estimate to the output interface whereon the estimate is outputted.
