What happens if you talk too loudly into a microphone during FM transmission?

When you speak too loudly into a microphone during FM transmission, audio distortion can occur. This happens because the microphone picks up sound levels that exceed its designed dynamic range, leading to clipping of the audio signal. As the sound gets too intense, the waveform becomes flattened, which results in a loss of clarity and introduction of unwanted artifacts in the audio.

In FM transmission, while the modulation is primarily amplitude variation, excessive loudness can cause the modulation to exceed the acceptable level, creating distortion that negatively affects sound quality. This distortion makes it difficult for the receiver to accurately reproduce the intended audio, leading to poor listening experiences.

The other choices do not accurately describe the effects of excessive loudness on FM transmission. For instance, audio quality does not improve under such conditions, signal strength doesn't increase simply due to loudness, and longer transmission range is not a result of distortion. Instead, it is important to maintain an appropriate audio input level to ensure clarity and fidelity in FM broadcasts.
