What is "over modulation" in communication?

Over modulation refers to a situation in audio communication where the signal level is too strong, leading to distortion or clipping of the sound. This commonly occurs when a speaker gets too close to the microphone or speaks loudly, which can cause the audio signal to exceed the maximum level that the recording or transmission medium can handle. This results in a degraded sound quality where certain parts of the audio may become unintelligible, effectively compromising the communication.

In contrast, using a deep voice for communication does not inherently lead to over modulation; it's more about the distance from the microphone and the volume of the voice. Speaking too far from the microphone typically results in low volume levels rather than distortion, and while excessive technical jargon can confuse the listener, it does not affect the audio quality in terms of modulation.
