The standard covers requirements, conditions, and procedures for threshold-of-hearing measurementsin a sound field. However, the standard may also be used for conducting other sound-field hearing testsand as a research tool for assessing the effects of listening conditions and headgear worn by the listeneron detectability of various test signals. Three sound fields are referenced in the standard: the free soundfield, the quasi-free sound field, and the diffuse sound field. The test signals covered by the standardare frequency-modulated tones (warble tones) and narrow-band noises. However, other calibratedsignals that meet requirements of this standard may also be used. The standard applies to binauralIistening to test signals presented by one or more loudspeakers in a test room. Monaural air conductionhearing thresholds may also be determined if the opposite ear can be properly occluded. Specialapplication of the standard to the assessment of spatial hearing is presented in Annex B.
