FIELD: medicine.
SUBSTANCE: invention relates to field of medicine, namely to otorhinolaryngology. Harmonic signals are formed. Their level is made step-by-step by means of step-by-step controlled attenuator. Frequency of harmonic signals is measured randomly within acoustic range of perception by means of convertible generator. Patient fixes signal of quantitative value of level of perceptibility threshold by means of registration unit. For the examined person not to become accustomed to dynamics of signal increase and decrease, fixation of perceptibility threshold is performed by alternate step-by-step supply of acoustic signal by increase and decrease of its intensity, with alternation of signal intensity.
EFFECT: method makes it possible to increase reliability of signal diagnostics.
