Childhood hearing level varies considerably within the range considered normal. Four classes of outcome were investigated for associations with hearing thresholds in this range: ability to identify speech in noise, neurocognitive ability, linguistic abil
averaged emission cochleograms drawn from the mean pseudothresholds of tone-burst e-OAEs at 6 stimulus frequencies between 500 Hz and 4 kHz and averaged pure-tone audiograms was analyzed, a clear difference was found among the three age groups in a frequency range between 500 Hz and 2 kHz...
What is the normal range for hematocrit by age? The normal ranges for hematocrit depend on the age after adolescence and the sex of the individual. Hematocrit normal ranges by age chart are shown here: The normal hematocrit ranges by age chart ...
The patients were matched according to age at implantation (mean age 44.5; SD 14.1; range 20–64), hearing loss in the ear to be implanted (which had largely retained low frequency hearing: hearing thresholds for 0.5 kHz of up to 80 dB), gender, and side of implantation. In addition, ...

In the past, researchers investigated silent lipreading in normal hearing subjects with functional neuroimaging tools and showed how the brain processes visual stimuli that are normally accompanied by an auditory counterpart. Previously, we showed activation differences between males and females in primary...
agetest repeatabilitynormative dataObjective: The objective was to assess the effect of age on thresholds for the TEN(HL) test for diagnosing dead regions in the cochlea, as a function of signal frequency and TEN(HL) level. Design: The TEN(HL) test was administered twice for each ear of ...
A good heart rate differs from individual to individual, and it depends upon your age and the kind of physical work you do. Given below is the chart showing normal heart rates by age. Table. Heart Rate by Age Range However, a heart rate that is lower than 60 per minute does not neces...
‘Normal’ hearing thresholds relate to speech-in-noise Audiometric thresholds (2-frequency average at 4–8 kHz across the left and right ears) accounted for 15% of the variance in speech-in-babble thresholds (r = 0.39,p < 0.001; 95% CI = 0.21–0.55). The correlation ...
In contrast, DPOAE growth measured in the same frequency range showed clear declines as early 30 years of age, particularly across moderate stimulus levels (L2 = 25–45 dB SPL). These substantial declines in DPOAE growth were not fully explained by differences in behavioral thresholds ...
