Creating acoustic comfort: Silence Effect

November 04, 2021

How many times has an annoying sound crept into our videoconferences? It is rare that we do not hear a dog barking, a car engine, a doorbell, or normal sounds around us. Perhaps, we have even become accustomed to it, but the truth is that on numerous occasions these noises can become very annoying; How many times have we had to say “please mute your microphones”?

Imagine how uncomfortable it can be for a student who is at home following an online class, if these annoying noises are joined by the normal, and probably even healthy, murmur of a class in progress. Because let’s remember that our classes, in general, are noisy, especially when the teacher is not explaining something but working individually, in pairs, or in groups, as we usually do in our classrooms. The situation can become very annoying when, in addition to this background “noise” (because let’s remember that the students at home what they will hear will be an annoying murmur), there is also the voice of the teacher who wants to keep quiet, or who tries to speak in front of a particularly noisy group, of which there are some…

Thanks to our “silence effect” that starts automatically at the beginning of a videoconference with ClassInTheBox, the acoustic comfort for remote participants, whether in a videoconference or in a class broadcast, is guaranteed. Our audio codecs filter out the human voice, transmitting it in high quality and eliminating all the background noise that disturbs the other party.

The silence effect is also responsible for the fact that when we connect the show mode (which allows us to project our voice through the speakers of the classroom, the room or the auditorium) our voice is not coupled and there are annoying echoes that we have all suffered, especially when we bring the microphone close to the speakers.

Therefore, remember that with ClassInTheBox, in addition to the visual communication achieved thanks to the alternation of the two cameras and the sharing of material (presentations, videos, apps, etc.) from the teacher’s screen, one of its main advantages is the creation of a comfortable acoustic environment where background noise is not an obstacle to receive the teacher’s or speaker’s audio with the highest possible quality.
