How Active Voice Amplifier Works
Active Voice Amplifier works at the software level. The microphone installed in the TV receives sound vibrations that are present in the room. If the background sound level exceeds the set level, the level is determined by testing and a gradation scale is developed. That automatically increases the level of reproducible sound, the program mixers installed in the TV software increase the volume level only in the frequency band of a person’s voice, this is from about 100 Hz to 4 kHz. Note that the software adjustment is balanced in such a way that a person who watches TV will hear the conversation in the transmission shown on TV, clearly and legibly.
