Abstract
Hearing impairment is the partial or total loss of hearing. There are approximately 34 million hearing impaired children in the world. The equipment used as a means of communication to improve interaction with society is very expensive, so in this study was built an electronic device with the ability to recognize some words configured as an emergency message. This equipment will be used as a basic means of communication for hearing impaired children at a very low price. The equipment consists of a transmitter and a receiver, which communicate over Wi-Fi 802.11 at distances between 0m and 95m using low-power electronic devices and recent technology such as WeMos D1 mini Lite cards. This device was tested on approximately 20 people caring for hearing impaired children, obtaining a measure of approval of approximately 74%. This is the first step in research that we plan to continue to reduce health gaps and improve communication for children with disabilities. Our group works for preventive health, reducing health gaps in the most vulnerable population.
Highlights
In the world, there are approximately 466 million people with a hearing-impairment of which 34 million children, according to the World Health Organization [1]
The solution for some of them is the cochlear implant, known as the bionic ear, is that device that is implanted through surgery, helping to improve hearing- impairment in children, helping them overcome these problems originating in the inner ear or cochlea
2) Voice recognition module v3: The voice recognition module used for the recording of the words that will cause an action on the receiving device, communicates through the serial port Tx and Rx, in order to record the words to be used, in addition to this the module only recognizes the voice of the person who recorded it according to the frequency of his voice, preventing outsiders from manipulating him
Summary
There are approximately 466 million people with a hearing-impairment (in adults over 40dB and in children at 30dB) of which 34 million children, according to the World Health Organization [1]. Hearingimpairment in children represents a severe public health problem, which the State should have as a priority, since progress can be dangerous throughout the country, despite having the hearing loss program that has granted about 500 implants cochlear, much more is needed to provide optimal care to all children who require it. This situation has been caused by the lack of medical instrumentation, which allows this condition to be diagnosed, in addition to lacking an institution with the necessary spaces and conditions to perform patient surgeries.
