Abstract

The systems, methods and associated devices performing diagnostic hearing tests which use a computer network to allow interaction between a test administration site and one or a plurality of remote patient sites. The test can be administered by an audiologist or clinician at a site remote from the patient, in a manner, which can allow interaction between the user and the clinician during at least a portion of the administration of the test. The diagnostic hearing tests can be performed such that they meet standardized guidelines such as ANSI requirements or certification standards and can include distortion product emission level measurements or middle ear compliance measurements.
