Discomfort level test. Frequency response adjustment Adjustment of the amplitude-frequency response (AFC) of headphones, bone vibrator and masking signal ensures precise tuning of each channel on an expanded frequency grid. The option allows calibration at any signal level in the range from 40 to 80 dB, which increases the accuracy of audiometric studies and ensures measurement stability under various operating conditions. Description of tests Tone in Noise Test The “Tone in Noise” test is an audiometric research method based on assessing the hearing thresholds of tonal signals under conditions of dosed masking with white noise. The method allows you to analyze changes in auditory sensitivity under the influence of noise masking and is used to clarify the nature of hearing impairment, including the differentiation of cochlear and retrocochlear pathologies. During the study, tonal signals are presented against a background of gradually increasing noise levels, which provides an accurate assessment of the dependence of the auditory threshold on the intensity of the masking signal. Stenger test The Stenger test is used in audiometry to detect asymmetric or feigned hearing loss when both ears are simultaneously stimulated with sound signals of the same frequency. The method is based on the Sterng phenomenon, in which the patient does not perceive a sound presented to the ear with worse hearing if a more intense signal is simultaneously presented to the better hearing ear. The test allows you to objectively assess the reliability of audiometric data and is used in the differential diagnosis of functional and organic hearing impairment. ABLB test The ABLB test (aural loudness equalization test) is used in audiometry to evaluate differences in loudness perception between the left and right ears when stimulated with pure tones. The method allows us to identify the phenomenon of loudness leveling (recruitment), characteristic of cochlear lesions, and is used in the differential diagnosis of sensorineural hearing loss. During the study, the patient is alternately presented with sound signals of varying intensity in both ears until a subjective sensation of equal volume is achieved. SISI test The SISI (Short-Term Loudness Sensitivity Index) test is used in audiometry to assess a patient's ability to detect minimal changes in sound intensity. The method is based on the presentation of a tone signal of constant volume with a periodic short-term increase in intensity by a fixed amount. The test is used for the differential diagnosis of cochlear lesions of the auditory analyzer and allows one to assess the presence of the recruitment phenomenon. Uploading data to removable media The function of uploading data to removable media ensures that the results of audiometric studies are saved for subsequent analysis, archiving or transfer to medical information systems. Examination results are saved in the device’s internal memory with the ability to export to a USB drive, which simplifies working with patient data and provides quick access to examination history. Support for transferring data to external media allows you to use the results in documentation, dynamic monitoring of patients and reporting in clinical practice.
