An examination of 1300 students between the ages of 10 and 20 who had not yet been exposed to industrial noise was performed in order to establish to what extent general environmental noise influences hearing. The fact that there was no age-dependent increase of high tone hearing loss, as well as the small correlation between hearing loss and total noise… (More)
Both the outer and inner nose as well as the position of the parietal bones of 972 patients at an age of 3 to 82, were examined giving evidence of the configuration of the infant's head at birth and thereby of the "severity" of the birth. In comparison with the sectio-patients the configuration of the infant's head in the birth canal reveals statistically… (More)
This paper describes an ongoing research and development project aimed at providing contextualised, individualised online writing support for postgraduate students. It is the result of a collaboration between UK and NZ academics who share similar challenges and concerns. The massification of higher education globally means that many tertiary students drawn… (More)
Auditory thresholds were obtained by controlling Preyer's pinna-reflex for sound pressure levels quantitatively and selectively for single frequencies. Under the reported test conditions the auditory thresholds are very well reproducible and quickly done.
The positive evidence of the caloric test increases, when the time-course of the induced heat wave in the petrous bone was eliminated, which differs from man to man. This is possible by changing head position during calorisation, so that a nearly rectangular stimulus results.
T HE EXACT contribution of phrenic nerve function to ventilation and its effects on lung volumes have not been clearly described in humans. A case is presented of intraoperative transection of the right phrenic nerve and the subsequent changes in pulmonary function resulting from diaphragmatic paralysis. A 64-year-old man was scheduled for a right anterior… (More)
The adequate stimulus of the semicircular canals by a rotatory acceleration is producing a nystagmus, whose graph of the postrotatorius I is adequate to a decreasing e-function. The constants of the function are calculabe, the variance is very small. The inadequate stimulus of the semicircular canals by caloric stimulation effects a nystagmus, which shows… (More)
After caloric stimulation with water at 30 degrees C for 30 sec an electronystagmogram (ENG) was registered. Simultaneously with the ENG the test person's nystagmus was observed by Frenzel's glasses. If the evaluation is limited to the frequency of the nystagmus and if it is possible to neglect the velocity of the slow phase, the simple observation through… (More)
