COMPENSATION
(“HEQ”)
The HEQ compensation produces a measurement that is intended as a basis for subsequent headphone EQ. A
subjectively neutral headphone will measure approximately flat with this compensation. Therefore, subsequent
EQ can use a flat EQ target, as indicated in Figure 12.
Note: as the diagram suggests, some adjustment to the target based on listening will be required. Please follow
the guidance in this application note:

FIELD COMPENSATION
(“IDF”)
The IDF compensation for IEMs is intended to equalize an IEM to a diffuse field response. We used the Etymotic
ER4SR as the model for this. (Note: you cannot directly compare headphone and IEM measurements.)
The suggested EQ target for this compensation is therefore flat with a 3 − 5 bass boost, as illustrated in Figure 13.
As always with EQ, some adjustment based on listening will be required.
