With only one test, gets the audiogram accurately and quickly without the cooperation of the patient and make an objective diagnosis in newborns and adults
Cochlear microphonics response are registered by two conventional surface electrodes placed behind the pinna (mastoid) and another one on the forehead. Data for each of the audiometric frequencies used in clinical procedures are obtained by a computer process reaches an identical audiometric profile obtained by conventional techniques. The system also provides a range of clinical information for the diagnosis of hearing disorders. All studies are performed without the cooperation of the patient, so it can be used even in premature newborns. The method provides fully reliable, as demonstrated in various hospitals in Madrid: Ramón y Cajal, La Paz, H. Clinico, among others. Given the extensive information obtained and the reliability of the system the results are superior to those obtained by other techniques, without increasing the cost of the studies. This solution has been developed by the Centre for Biomedical Technology of the Technical University of Madrid.
Cochlear microphonics, are the response to sound stimulation of the auditory sensory receptors. Due to its small magnitude, they are difficult to register and for this reason, they are not currently used for diagnosis in clinical audiology.
Our technique completely eliminates external perturbations that could mask these biological signals, achieving more accurate results than those obtained with other techniques. Besides the usual audiogram, the differential intensity level (recruitment) and other parameters and diagnostic audiological research interest is determined.
"AudioMC make simple and reliable diagnosis of hearing disorders in neonates and patients with little or no responsiveness, which so far has not been achieved with other techniques"
“Our solution offers audiometric objective diagnosis in cases in which only screening is possible nowadays, in very few minutes and in a cost-effective way”
