CH hello, this is my first attempt. I used the acronym is whether the words in full.
starting the acronym: clean, readable font, in red with a light reflection effect to make the logo fresh and modern but at the same time professional. C has been treated, making it similar to an ear. inside I introduced three white bands representing the frequencies and thus the accessibility to the "feel"
for the words whole, has been incorporated into a kind of banner with the same effect as a reflection
hope that you like and do not hesitate to ask for changes of any kind
