title: Digital instrument for measurement of aural acoustic immittance: a preliminary report.
abstract: Development of techniques for measurement of aural acoustic immittance (AAI) is reviewed. Measurement characteristics of selected AAI instruments are compared. Real-ear data obtained with a digital instrument are presented. Review of data support the suggestion that digital AAI instruments promote development of quantitative measurement protocols with greater efficiency and power.
