Audio feedback in a video call can be caused by several factors, including:
Proximity of microphone and speakers: When the microphone picks up sound from the speakers, it creates a loop, resulting in feedback.
Volume settings: High speaker volume or microphone sensitivity can lead to feedback as the sound is picked up and re-amplified.
Poor-quality equipment: Low-quality microphones or speakers may produce feedback due to their design or performance limitations.
Room acoustics: Reverberation or echo in the room can contribute to feedback by amplifying sound reflections.
Network latency: Delay in audio transmission over the network can cause overlapping audio, leading to feedback.
Interference: External sources such as electronic devices or radio signals can interfere with audio transmission, leading to feedback.
To prevent audio feedback, ensure that the microphone and speakers are adequately spaced, adjust volume settings appropriately, use high-quality equipment, optimise room acoustics, minimise network latency, keep software updated, and reduce external interference sources.
