The AC440 sof tware is an independent two-channel audiometer. It f eatures tone audiometry f or air and
bone, speech testing and a variety of masking and signal types. Stimuli are presented using the PC
keyboard, mouse, or a dedicated audiometry keyboard. Test results are displayed on screen and saved to
the associated database (e.g., Noah, OtoAccess®). They are immediately available f or inspection, hearing
aid f itting, printout, export, and so on. The AC440 module can also be operated external to a database in
