The Zoom desktop client uses ultrasonic sound to detect its proximity to a Zoom Room or another device joined into the meeting. In addition, the Zoom Desktop Client will automatically disable computer audio to prevent audio echo in a Zoom Room.

Prerequisites for eliminating echoes with proximity detection

• Zoom Rooms global minimum version or higher
• Zoom Rooms controller global minimum version or higher
• Automatic direct sharing using ultrasonic proximity signal option is enabled

Instructions

Since Zoom Rooms are the audio source, the Zoom Desktop Client will automatically disable computer audio (both speaker and microphone audio) if it detects proximity to a Zoom Room. You do not have to do anything if this feature is enabled.
