Aim of study: Hearing loss caused by exposure to recreational noise is considered a devastating disability, not least because it is virtually 100 percent preventable. No consensus exists regarding the magnitude of the risk. This study prospectively assesses the hearing threshold in a group of Portuguese adolescents, related to their habits of noise exposure. Method: […]
Introdução: O diagnóstico precoce de surdez infantil é um requisito essencial para uma correcção apropriada da hipoacusia. Até recentemente o rastreio auditivo baseava-se exclusivamente na avaliação dos Potenciais Evocados Auditivos do Tronco Cerebral (PEA), um método exigente em termos técnicos, demorado e que implica frequentemente uma sedação da criança. O advento das Otoemissões Acústicas (OEA), […]
During the last years, cellular phones produced a real, total and incontrovertible revolution, involving the whole social and environmental domain. However, to date, there is only a reduced knowledge on what are the biological systems influenced by the use of this kind of devices. Among them, the produced electromagnetic fields (EMF) could affect, before any […]
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 […]
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 […]
During the last half century, medical developments have expedited an increase of expectation of life, all over the world. This extension of life has made that some pathologies that in former years were considered of low prevalence, nowadays they have become top priority for public health.
Some new therapies for tinnitus employ bone-conducted sound in the high audio and ultrasonic frequencies, but there has been little previous research on sound transmission through the head at these 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.
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).
All of 1,420 children seen for clarification of a hearing disorder or to follow up for known difficulty in hearing were questioned as to whether they experienced tinnitus. The interview was carried out after a hearing test was conducted, which was based on play audiometry or normal pure-tone threshold audiometry, depending on the age of […]
