Immittance is calculated using which two measurements?

Immittance refers to the measure of how easily energy flows through the middle ear system, and it is a combined term that encompasses both admittance and impedance. Admittance is the measure of how much sound energy is accepted by the system, while impedance refers to the opposition to sound energy flow. The relationship between these two is critical in audiometric assessments, particularly in tympanometry, where the ability of the middle ear to transmit sound is evaluated.

The measurements of admittance and impedance provide important information regarding the functioning of the middle ear, helping to identify potential conditions such as fluid presence or eustachian tube dysfunction. Understanding these concepts is essential for audiologists when interpreting tympanometric results and diagnosing auditory disorders. Other provided options do not align with the fundamental definitions of immittance; thus, they do not accurately describe the necessary measurements involved in this concept.
