Interaction - like communication between events, teachers and students, and board members - is the most critical aspect of a meeting.

It is precisely with video conferencing systems that participants from different locations can communicate smoothly, but communication between people in the same room is often overlooked.

Traditional audio systems can allow the audience to hear the speaker or lecturer's voice, but cannot allow the audience to clearly hear each other's voices.

Why can't you hear clearly?

1. The volume level naturally decreases as distance increases

As the distance between the speaker and the audience increases, the volume level will naturally decrease.

In a typical indoor environment, the consonant carrier frequency - medium and high frequency, which is crucial to speech recognition, is often first offset by background noise and chaotic acoustic reflection.

2. Sound spreads forward from the speaker's mouth

Due to the fact that sound mainly travels forward from the speaker's mouth, this impact becomes more severe when people are facing each other in front of each other.

But even in face-to-face communication, if the person sitting at one end of the room does not use Dantian's power to make a sound, the person on the other end may not be able to hear what the other person is saying.

Even worse, people may not complain about these issues because they believe that they alone cannot hear them clearly.

Solution: Voice Enhancement

The solution to this problem is a special audio system called "voice enhancement".

The voice enhancement system amplifies the voices of people in a certain area of the room to a sufficient level, so that people in other areas of the room can clearly hear their voices.

Unlike traditional public address systems, speech enhancement systems only enhance those frequency ranges that are most critical for speech recognition, and only recover the volume loss caused by distance between the speaker and the audience in the room.

Usually, a voice enhancement system increases the volume level in the room by up to 3 to 6 decibels. The resulting effect is very natural and imperceptible, to the extent that many users do not realize the existence of voice enhancement until they turn off the audio system.
