Why is it recommended to use multi-frequency steady-state evoked potentials to estimate hearing loss when fitting hearing aids for infants and young children?

Multi-frequency steady-state evoked potential detection has the following characteristics:

(1) Multi-frequency steady-state evoked potentials are used to generate audiograms by statistical analysis of evoked potentials;

(2) Multi-frequency steady-state evoked potential is an “objective” test. For infants and young children that are difficult to use traditional behavioral audiometry to accurately test, multi-frequency steady-state (ASSR) can be used to predict audiograms without the cooperation of the subject (can be Sleeping, anesthetized or taking sedatives) automatic test results, easy to accurately judge:

(3) Multi-frequency steady-state evoked potentials use spectrum analysis to analyze the entire frequency range;

(4) Multi-frequency steady-state evoked potential audiometry can be used without anesthetics;

(5) Multi-frequency steady-state evoked potential can be measured to 130dBHL (ABR can only measure 100dBHL);

successful  Hearing aid  Fitting must rely on accurate hearing threshold testing data. For 6-month-old infants, it is difficult for behavioral hearing tests to detect accurate hearing thresholds. The results of behavioral hearing tests must be verified by objective tests, and the results obtained from objective tests Behavioral audiometry must be required to verify. Although brainstem evoked potentials and 40Hz mid-latency response are objective detection methods, they cannot fully and accurately estimate the degree of hearing loss in children.

Therefore, the multi-frequency steady-state evoked potential test is one of the reliable and important methods for infant hearing detection. It is extremely important for determining the degree of hearing loss of infants and young children (especially 6 months) at various frequencies. It is the best choice for infant hearing aids. Equipped with indispensable testing methods, but still need to cooperate with the other diagnostic testing methods mentioned above.
