Students attend this class just as they do other specials, in some cases with more frequency or total time allotment than other specials.
Symptoms are rated on a 6-point Likert scale, with higher scores indicating more frequency or intense symptoms.
Subjects with a conductive component in the audiogram (presence of an air-bone gap at two or more frequencies equal or higher than 10 dB HL) were excluded from the final sample.
*ZDV = zidovudine, †ddI = didanosine, ‡RNA = ribonucleic acid, §PTA = pure tone average At study entry, 22 of 33 subjects had a hearing level greater than 25 dB at one or more frequencies in one or both ears, 16 had at least one hearing level greater than 40 dB and 7 had at least one hearing level greater than 60 dB.
Physical systems, the natural frequencies of which depend parametrically on certain quantities, may exhibit the phenomenon of frequency coalescence, when two or more natural frequencies become equal; or the phenomenon of avoided crossings, when two or more frequencies approach rapidly and then avoid crossing each other.
Recently, there has been interest in designing multiple-frequency notch filters that aim to suppress two or more frequencies of an input signal [20-25 [20-25
Generally, dynamic flow events have been found to introduce contaminating signal components at one or more frequencies, other than that of the meter drive.
A feasible solution/assignment to this input is a function Y ¯ : T ¯ → 2 F, mapping each set uniquely to one or more frequencies.
By comparing two or more frequencies, detecting the difference between the actual frequency and the expectation frequency based on distribution hypothesis in a certain significance level, which reflects whether there exists significant difference between the actual level and theoretical level.
Furthermore, SNHL of greater than 30 dB at one or more frequencies in both ears with evidence of active deterioration (elevated threshold) in at least one ear of 15 dB at one frequency (excluding 250 Hz as a sole indicator), or 10 dB at 2+ frequencies developing in >3 days but <90 days [3], [16].
