Identification of audio and room parameters for optimum speech intelligibility in room

The installation of electronic amplification system in the meeting or conference room is intended to having a louder, clear and an even sound propagation. Furthermore the conversation exchanged will be at ease, since speakers do not have to raise their voice to be heard. However, the interaction bet...

Electronics Nuclear engineering The installation of electronic amplification system in the meeting or conference room is intended to having a louder, clear and an even sound propagation.
