The free-field correction values for earphones provide the loudness based equivalence to loudspeaker presentation. Correction values are especially used for the calibration of audiometric equipment for speech audiometry performed with headphones. Calibration values may be found in, e.g. the ISO 389 series of standards.

At a given frequency in the sinusoidal steady state, the free-field response is the ratio of the out put voltage of the microphone to the sound pres sure which existed at the microphone's acoustic center (or specified reference point) prior to the introduction of the microphone into the path of a plane progressive sound wave.

When the microphone is of the free field type, SPL is read directly from the SLM. If a pressure microphone is used, then appropriate corrections must be made. These corrections, as well as information regarding angle of incidence and compensations for diffuse sound field, are usually available from the manufacturer of the SLM.
