Effect of sedation upon evoked response audiometry: Amplitude and latency vs sound pressure level
Autor: T. Karnahl, C. D. Benning
Publikováno v: Archiv f�r klinische und experimentelle Ohren- Nasen- und Kehlkopfheilkunde. 201:181-188
The first part of this paper is concerned with the acoustically evoked responses for a frequency of 1 kHz, obtained in eleven, normal hearing, adult subjects. Amplitudes as well as latencies were different in the adapted and non-adapted states of the

[Electric response audiometry (brain stem potentials and late potential N1) in patients with acoustic neurinoma or space-occupying lesion in the region of the brain stem]
Autor: C, Zöllner, T, Karnahl, K, Weigel
Publikováno v: Neurochirurgia. 21(6)
In patients with acoustic neuronoma or space-occupying lesion in the region of the brainstem we recorded preoperatively the brainstem potentials as well as the late potential N1. With one exception all patients investigated showed changes in the brai

[Age-dependent electric response audiometry (ERA)-findings in correlation with speech development (author's transl)]
Autor: T, Karnahl, C, Holm
Publikováno v: HNO. 23(9)
The occurrence of periods of speech-certainty and speech-uncertainty can be observed in normal as well as in children impaired with hearing, voice and speech defects. This behaviour of voice and speech development has not yet been explained by subjec

[ERA-findings by 'cortical hearing disorder' (author's transl)]
Autor: C, Zöllner, T, Karnahl, P, Pedersen
Publikováno v: Archives of oto-rhino-laryngology. 217(4)
Since about the last 2 years the late potential's component N1 (90--110 ms) as well as the early acoustically evoked potentials, appearing in a latency range of 1--8 ms and consisting of the nerve action potential (Pot. I) and the brain-stem potentia

[Electric response audiometry (brainstem potentials, late auditory potential N1): observations at patients suffering from menière's disease or sudden hearing loss (author's transl)]
Autor: C, Zöllner, T, Karnahl
Publikováno v: Laryngologie, Rhinologie, Otologie. 58(4)
At some patients suffering from Menière's disease or sudden hearing loss the late auditory potential N1 and the brainstem potentials were registered. It could be shown, that an exact differential diagnosis between these both illnesses was not possib

['On-line artefact rejection' at electric response audiometry (ERA). Use of an active, analog delay line as buffer in combination with a recognition of disturbing signals (author's transl)]
Autor: P, Pedersen, T, Karnahl, C, Zöllner
Publikováno v: Archives of oto-rhino-laryngology. 218(1-2)
Some brief theoretical considerations about an artefact rejection basing upon the valuation of amplitudes are followed by a report on a new development of an "on-line artefact rejection" which uses an active analog delay line as buffer combined with

[Electrocochleographic potential pattern, recorded by different pick-ups (author's transl)]
Autor: C, Zöllner, T, Karnahl
Publikováno v: Laryngologie, Rhinologie, Otologie. 54(8)
At electrocochleography, the active electrode was placed on the earlobe, the mastoid, the nasopharynx, the hard palate and the external ear-canal respectively. It could be shown that the potential pattern, consisting of five components, during the fi

At some patients suffering from Menières disease or sudden hearing loss the brainstem potentials and the late auditory potential N1 were registered. It could be shown that an exact differential diagnosis between these both illnesses was not possible
