Background: Cochlear implant processors operate by the sound processing strategies designed by the manufacturers. The outcomes of free field audiometry, frequently employed after fitting, may vary depending on the working principle of the strategy utilized and the type of stimulus employed. Aims: to compare the types of stimuli used in the free field audiometry test following Cochlear brand cochlear implant fitting. Method: A total of 14 cochlear implant users, comprising four females and 10 males, with a mean age of 34.57 years (standard deviation: 12.41 years; age range: 19–58 years), were included in the study. The participants had been using cochlear implants for a minimum of one year and a maximum of 31 years. Following the cochlear implant fitting, the Digital Noise Cancellation function and Directional Microphone technology were deactivated, and auditory thresholds were determined at 250, 500, 1k, 2k, 4k, 6k, and 8k Hz with Narrow Band Noise (NBN), Modulated Tone (Warble Tone/WT), and Pure Tone (PT), respectively. Subsequently, speech recognition thresholds were determined using Ling sounds. The distribution of the results was analyzed using the Shapiro-Wilk test. Statistical analysis was conducted using the Friedman, Wilcoxon paired comparison, and Spearman correlation tests. Results: In the free field audiometry test, a notable discrepancy was observed in the hearing thresholds elicited by distinct stimuli across all frequencies, except 250 Hz. In the paired comparisons, it was observed that the free field results obtained with modulated tones were more compatible with the results of speech tests. Conclusion: It is recommended that Cochlear brand cochlear implants be evaluated in the free field with warble tones. Furthermore, as a result of the aforementioned test with WT, it is recommended to use a correction factor of -10 dB for the M stimulus, -5 dB for the u stimulus, and +5 dB for the ş stimulus
