Measurement of bone conduction levels for high frequencies
For assessment of safety, it is necessary to measure the maximum possible force exerted by a bone conduction device coupled to the human head.

Doppler ultrasonography in tinnitus patients
Tinnitus can be functionally measured and localized through sensorimotor and neurosensory tests. According to our Neurofisiología Otooftalmológica data bank, 60% of patients requiring a consultation have a history of cardiocirculatory disorders. This figure has moved us to study cerebrovascular processes in those patients seeking consultation for a tinnitus symptom only. The sudden appearance of the […]
Vertigo as a prognostic sign in sudden sensorineural hearing loss
Several prognostic indicators of favorable outcome in idiopathic sudden sensorineural hearing loss (ISSHL) have been proposed: an initial profound hearing loss, a down-sloping audiometric curve, advanced age, and the presence of vertigo. The latter has been disputed in the literature. The present study addressed the correlation between vertigo and outcome of ISSHL. Sixty-seven patients with […]
Effects of discotheque music on audiometric results and central acoustic evoked neuromagnetic responses
Audiograms and auditory evoked magnetic fields (AEFs) were observed in young male and female adults at different ages before and after being exposed to discotheque music for 4 hours. Sound pressure levels (SPLs) ranged from 95 dB (SPL) up to 130 dB (SPL).
The alteration of hearing process in antiorthostatic position modelling microgravitation
The cranial shifting of body fluids developing in microgravity can be modelled by –300 head-down tilt body position (antiorthostatic posture) on Earth. Authors examined a group of 13 healthy voluntary young men in antiorthostatic posture and recorded the alteration of parameters in complex examinations. Among them pure tone threshold and speech threshold examinations were carried […]
