4 Audiogram Patient s Audiogram Enter patient s audiogram using AC and/or BC thresholds, unmasked or masked or No Response (NR). If this audiogram is imported from NOAH, it cannot be changed. Entering Hearing Thresholds There are two ways to plot the patient's hearing thresholds: Plot the hearing thresholds directly into the audiogram by pointing and clicking with a mouse. Thresholds can be entered in 5 db increments in the graph. Enter hearing thresholds in the table below the audiogram using the keyboard. Thresholds can be entered in 1 db increments. To enter masked thresholds, click the M Button in combination with either AC or BC. To enter a No Response (NR), enter a threshold, then right-click the threshold and select No Response from the drop down list. Note: The prescription will be based on the BC thresholds. If bone conduction information is not entered, the fitting software uses a threshold value of 0 db HL. If some thresholds are missing, the fitting software will estimate a value based on the adjoining thresholds. Audiogram Buttons Button Functionality Delete Button Erases a curve of thresholds on the right and/or left side(s). To erase only one threshold, right-click and choose remove. BC BC Button Click to enter bone conduction (BC) thresholds. AC AC Button Click to enter air conduction (AC) thresholds. M Button Click to note masking for AC or BC thresholds.
