ABSTRACT

Hearing loss is highly incident among newborns. Early intervention during the period of auditory maturation allows adequate levels of intellectual development to be achieved. The development of a Transient Otoacoustic Emissions Recorder is proposed as part of a neonatal screening system based on high-performance microcontrollers. The test consists of periodically applying a click stimulus to obtain the cochlear response. The acquired signals are averaged and the Fast Fourier Transform is applied. The spectrum obtained is divided into half-octave bands to assess the correlation as well as the signal-noise ratio. If these parameters are greater than the reference thresholds in most of the bands, the patient is considered suitable for normal cognitive development. The firmware was implemented on the STM32F405 processor and evaluated with the Baby Isao simulator; obtaining a sensitivity of 87.5% and a specificity of 93.75%.
