“…Numerous solutions for resolving this issue, some of which are more or less efficient, have been proposed. Among the best solutions so far, with excellent hopes for positive development in terms of technical performances, is the cochlear implant [1][2][3][4][5][6][7][8][9]. A cochlear implant is an electronic medical device that replaces the function of the damaged inner ear by enabling radio communication between two antennas and work through electrical stimulation of an array of electrodes implanted in the cochlea.…”

The present paper discusses the climatic effects of humidity and temperature on cochlear implant functioning and the quality of the electrical sound signal. MATLAB Simulink simulations were prepared, offering insights into signal behavior under such climatic parameter changes. A simulation setup of the cochlear implant was developed, where a source type selection was used to change between a voice recording and a “chirp” sound. In addition, a DC blocking filter was applied to the input signal. A simulation code, with the application of the climatic influence via the air attenuation function, was developed. Thereby, the attenuation of temperature and humidity in the sound atmospheric circulation of the input signal, at T = 0 °C and RH = 0% and at T = 36 °C and RH = 40% was graphically represented. The results of the electrical pulse generator for each of the eight channels, with the IIR filter, Gaussian noise, temperature variation, humidity influence, and control of denoise block activity, were thus obtained.
