Free-Field Audiometric Speech Testing in a One-Room ...
https://jamanetwork.com/journals/jamaotolaryngology/fullarticle/597906
The need of speech audiometry to supplement pure-tone audiometry has been firmly established. Many otolaryngologists have been discouraged from adapting their offices for this use because the number of hearing tests done would not justify the expense of a standard two-room testing arrangement.

Speech Audiometry/Free-Field Aided Test. Speech audiometry is a hearing test that uses speech stimulus to find out about a person’s ability to hear and understand speech. Speech test helps in different aspects: To cross check the puretone hearing thresholds. To assess the suitability of various implant solutions.

https://pubmed.ncbi.nlm.nih.gov/27765530/
For these tests, an environment in calibrated free field was arranged where speech was presented to the subject being tested from two speakers located at 45°, and noise from a third speaker, located at 180°. Results: All participants had speech audiometry results in the free field between 88% and 100% in the three listening situations.

https://pubmed.ncbi.nlm.nih.gov/21299375/
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.

Sound Field Measurement Tutorial
https://www.asha.org/policy/RP1991-00025/
For the measurement of speech recognition thresholds (SRTs) in the sound field, it is assumed that any sound field that meets the permissible ambient noise levels shown in Table 2 is also adequate for speech threshold testing under the same conditions. For measuring SRTs, components above the 4000 Hz octave band need not be considered.

bone conduction thresholds, and/or speech discrimination testing. Sometimes these evaluations were done on all NHANES examinees, and some surveys included hearing evaluations on only a subset of examinees (such as children or adults). Table 1-1 summarizes the audiometric procedures included in each of the health examination surveys since 1960:
