Defined in the ANSI standard – ANSI s3.39-1987 (R2007) as “the dynamic measure of acoustic immitance in the ear canal as a function of changes in air pressure in the ear canal” Katz pg. 175 HIMSA highly recommends the below 3rd party documentation for individuals not familiar with Audiology.

Edition Copyright © 2017 HIMSA II K/S REV History REV1 / September 2011, first release of format 100 translated to XSD REV2 / July 2012, HIMSA released REV 2 of the IMP 500 data standard in conjunction with Noah 4.3. was made because ImpedanceMeasurementCondition_Type > Frequency needed to be changed from mandatory to optional. This change was needed because the element is used depending on the SignalOutput. All changes for REV 2 are marked between the “!!” symbols. REV 3 / May 2014, clear up annotations dealing with the description of Contra Reflex Measurement and IPSI Reflex Measurement REV 4 / August 9 2015 - Annotation updates only. See new annotations for attributes ValidatedByNOAH and ConvertedFromDataStandard REV 5 / April 18 2017 With the release of the Noah 4 Audiogram module (version 1.2) HIMSA has updated the Admittance runtime data converter format 100 –> 500. The changes that were made were done so to address issues where the previous converter would create a format 500 XML file that would pass validation. This was a known issue with the original move to XML based data standards. However, HIMSA recently discovered that there was an undesirable side effect when creating updated format (e.g. format 501). Without fixing this issue the invalid XML caused further problems converting to format 501. The detailed changes can be found by searching for the text “@@ REV 5 Converter Change 100>500” The general changes are choosing default values if not present or entering in a value of -32676 rather than a value of zero (as this can be a valid result). REV 6 / July 30 2018 It has been brought to HIMSA's attention that the ResultOfReflexTest annotations for REFLEX are incorrect. The values were incorrectly carried over from fromat 100. This issue has existed since the first REV of format 500. The correct values of 1=True and 0=False are not documented.

The muscle contraction is a normal bilateral response to acoustic or other eliciting stimuli, (which is not necessarily bilateral). The amount of contraction and subsequent acoustic reflex decay are measured by immitance audiometry. The reflex is commonly described as ipsilateral or contralateral depending on which side the response is observed relative to the stimulus. Usually manual inspection of the recorded response is required to verify that a reflex response has been recorded as normal breathing can cause artefact on the test recordings. Generally there are 3 tests undertaken using the acoustic reflex response, which are: 1) Normal reflex test 2) Reflex decay test 3) Reflex latency test 1) Normal reflex test Changes in the immitance of the ear are monitored as a tonal or noise stimuli is presented which elicits an acoustic reflex. The test establishes the lowest sound level that elicits a reliable acoustic reflex response which is seen as a measurable change in acoustic immitance. As the acoustic reflex is a bilateral response we can stimulate either ear and record a response from the same or opposite ear. The stimulus can be presented in the same ear as the immitance recording and this is called an ipsilateral reflex. Alternatively the immitance can be recorded in the opposite ear to the stimulus and this is called a contralateral reflex. Ipsilateral and contralateral reflexes test different neural pathways. For clarity the definitions used are detailed below. + Right contralateral reflex denotes the stimulus is delivered in the left ear and the probe recording the response is in the right ear. + Left contralateral reflex denotes the stimulus is delivered in the right ear and the probe recording the response is in the left ear. + Right ipsilateral denotes stimulus and probe in the right ear. + Left ipsilateral denotes stimulus and probe in left ear. Ref: Pg 207 Katz 2) Reflex Decay test Acoustic reflex decay or adaptation, is the reduction in the magnitude of the acoustic reflex response during the presentation of a sustained stimulus. (pg 220 Katz) Test frequencies tend to be 500Hz and 1000Hz as the reflex tends to naturally rapidly decay at high frequencies. A reflex is said to decay if it falls to 50% or less of its original value in the 10 or 30 second stimulus time. Abnormally rapid reflex decay is associated with retrocochlear hearing loss. This curve illustrates the normal situation where the decay value is negative. The formula used for calculating the decay is Y2 - Y1 _______ Decay = Y1 . 100 percent. Range [0..100] percent. 3) Reflex Latency test Acoustic reflex latency refers to how long it takes for the acoustic reflex to occur after the stimulus is presented. The delay is measured from the onset of the stimulus until the beginning of the reflex response. (pg 223 Katz). Generally taken as the time it takes after the stimulus is presented for the immitance change to rise to 10% of it’s eventual value. The latency period tends to be substantially increased in retrocochlear hearing losses. ## reflexTest ##</xs:documentation> </xs:annotation> </xs:element> <xs:element name="EustachianTubeFunctionIntactEarDrumTest" type="EustachianTubeFunctionIntactEarDrumTest" minOccurs="0"> <xs:annotation> <xs:documentation>Eustachian Tube Test (Intact ear drum) The principle of this test is to record a maximum compliance point and if it is recorded at a significantly negative pressure to continue the test.

Since 1 cubic cm is equal to 1 ml, the three admittance units therefore should yield the same numeric values. + degree_3600 / If polar notation of the complex admittance is preferred, this measure expresses the phase angle in tenths of a degree. + deka_Pascal / Pressure in tens of Pascal, daPa, Pa/10. 1 daPa equals 1 mm of water. 6/25/2012 Annotation The IMP standard format 100 defined the possible values in the following manner • cubicCentiMetre_100 -- Cubic Centi Metre x 100 • milliLitre_100 -- Milli Litre x 100 • milli_mho -- Milli mho x 100 i.e. "SI-mho" • degree_3600 -- Phase in degrees x 10 • deka_Pascal -- Pressure in deka Pascal (daPa or tens of Pa) This means that a module saving data would set the compliance unit, using the list above, but would also have to save the compliance value accordingly. For example, if the unit was cubiccenterMetre then the value would have to be X 100. This concept was used as the original header file did not have the ability to use decimal values. While HIMSA migrated this standard (format 500) to XML we in almost all cases defined the xml element as a decimal where the format value was defined as “value”X100 ect. In this case we are not able to make this similar type of change as value will in some cases by X100, X10, or nothing. If a module is saving data using format 500 then it is mandatory that the developer save the value as an integer by multiplying the value according to the list of values above. Conversely, a module reading data must divide the integer accordingly.
