METHOD FOR ADAPTIVE INVERSE TONAL SCREENING OF AUDIBILITY LEVEL Russian patent published in 2025 - IPC A61B5/12 

FIELD: medicine.

SUBSTANCE: invention relates to medicine, namely to a method for adaptive inverse tonal screening of the audibility level. In the automatic mode, the patient is presented with audio signals at different frequencies when the audio signal levels change. To form test sequences, tone signal levels of 5, 10, 20, 35 and 50 dB are used. Test "0" is performed with a tone signal level of 20 dB. If the patient responded “There is a signal” at all presented frequencies, the test “-1” is performed with a tone signal level of 10 dB. If the patient replied “There is a signal” at all presented frequencies, test “-2” with a tone signal level of 5 dB. If the patient replied “There is signal” at all presented frequencies, the examination is completed and “excellent audibility” is determined. If the response “No signal” is received from the patient at least at one of the frequencies, the examination is terminated and “good audibility” is determined. If as a result of the test “-1” from the patient there is a response “No signal” at least at one of the frequencies, the examination is completed and the “Norm of audibility” is determined. If as a result of the test “0” from the patient there is a response “No signal” at least at one of the frequencies, the test “1” is performed with a tone signal level of 35 dB. If the patient has responded “There is a signal” at all presented frequencies, the examination is terminated and a potential “mild hearing loss” is determined. If as a result of the test “1” the patient responded “No signal” at least at one of the frequencies, test “2” is performed with the tone signal level of 50 dB. If the patient replied “There is signal” at all presented frequencies, the examination is terminated and “average hearing loss” is determined. If as a result of the test “2” the patient replied “No signal” at least at one of the frequencies, the study is completed and “high hearing loss” is determined.

EFFECT: shorter examination time and higher diagnostic accuracy.
