However, another cross-sectional study based on the Longitudinal Study of Children Survey of cohort aged 4 to 5 years has used this hearing variable and reported association between hearing impairment and language development, educational outcome, and metal health in children [ 14].
Univariate conditional logistic regression analysis for the healthy group and the COPD group was computed for the hearing impairment variables controlling for matching variable age.
Employing a repeated measures design with two independent variables (hearing condition and audio condition) and one between groups independent variable (native language), the results revealed the beneficial effects on noise cancelling headphones on performance.
The hearing-related outcome variables included are hearing loss (yes), tinnitus, sound sensitivity (ie, hyperacusis) and sound-induced auditory fatigue (once a week or more often), general hearing status (poor or very poor) and difficulty perceiving speech ('yes' both at work and in leisure time).
You will hear the key variables that so many have mimicked — a love of the dramatic line and a generous variety of vocal strategies (strobing vibrato, whispering, shrieking, flinty high notes that enter an octave above your expectation).
I had heard of dummy variables previously but never seen a practical example.
As shown in Fig. S1, 37 of the 107 matrilineal relatives exhibited bilateral hearing impairment with variable severity ranged from profound, severe, moderate to mild hearing loss, and 11 subjects had a history of aminoglycoside exposure.
Hearing loss was variable among patients.
MD has a clinical heterogeneity and the time course of the episodes of vertigo and hearing loss is variable.
Hearing loss is variable in the human population, and polymorphisms are associated with familial, environmental and drug induced adult-onset hearing loss [ 55- 57].
