A method for providing decision support includes using a programmed computer to input a regression model specification, and to repeat the input a plurality of times to obtain and store a plurality of regression model specifications. The double talk detector declares near-end speech to be present if an estimated power level of the upper band signals exceeds the upper adaptive decision threshold value, and declares the near-end speech to be absent if the estimated power level of the upper band signals falls below the lower adaptive decision threshold value for a predetermined number of iterative cycles. The electrode assembly includes an electrically conductive tip electrode and a coupler which is connected between the tip electrode and the distal end of the flexible tubing. A second baffle is located to direct cooling air over a back of the remote radio head.
