Abstract
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.
Highlights
We start by giving the main scientific arguments for our work, we present the cochlear implant and make an important analysis of the electrical signal in the cochlear implant, and its behavior based on temperature and humidity, via MATLAB Simulink simulations
Thereby, the cochlear implant signal source block, was introduced, where source type selection was used to change between a voice recording and a “chirp” sound, and again on the DC blocking filter, which was applied to the input signal
The simulation of a cochlear implant using MATLAB Simulink started by organizing a simulation setup of the cochlear implant, where a source type selection was used to change between a voice recording and a “chirp” sound
Summary
Hearing is an important component of human beings’ quality of life, at any age. The decrease of hearing capability towards deafness, and its inherent social complications, can be a major source of discomfort. As babies learn through speech recognition, the fact that they cannot hear may lead to the mispronunciation of words and difficulties in learning language. These challenges may result in major setbacks in their life and in human interaction, with respect to other children their age. Without proper treatment, they may require special assistance within society
