Acoustic Impedance Tests (also known as Impedance Tests, Acoustic, Acoustic Impedance Test): Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests

Definition

Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).

Common questions about Acoustic Impedance Tests

What does Acoustic Impedance Tests mean in medicine?
Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance). This definition is taken from the National Library of Medicine's MeSH (Medical Subject Headings) 2026 release, which is the standard vocabulary used to index PubMed and most medical literature.
Is Acoustic Impedance Tests known by any other names?
Yes. Acoustic Impedance Tests is also referred to as Impedance Tests, Acoustic, Acoustic Impedance Test, Impedance Test, Acoustic, Test, Acoustic Impedance in different clinical, research and patient-facing contexts. The MeSH descriptor groups all of these synonyms under a single canonical concept so research and records stay consistent.
Where does Acoustic Impedance Tests sit in the medical classification?
Acoustic Impedance Tests falls under the broader medical category "Analytical, Diagnostic and Therapeutic Techniques and Equipment" in the MeSH hierarchy (tree numbers: E01.370.382.375.050). Browsing the related concepts on this page takes you to neighbouring topics in the same branch of medicine.
