Velocity microphone referred to as a
- Omni directional microphone
- Uni-directional microphone
- Lapel microphone
- Ribbon microphone
Correct Ans: (D)
Explanation:
A velocity microphone, more widely recognized as a ribbon microphone, operates on the principle of sound pressure velocity rather than pressure level alone. This unique mechanism involves a thin metal ribbon—usually aluminum—suspended in a magnetic field. When sound waves strike the ribbon, they cause it to vibrate. These vibrations generate an electrical signal, which replicates the original audio with high accuracy.
Unlike dynamic or condenser microphones, ribbon microphones are extremely sensitive to subtle sound variations. Consequently, they have gained popularity in professional recording environments, particularly for capturing vocals, acoustic instruments, and broadcast-quality audio. Their figure-eight pickup pattern, which picks up sound from the front and back while rejecting the sides, also makes them suitable for nuanced stereo or ambient recordings.
Historically, audio engineers and broadcasters favored these microphones for their natural, warm sound reproduction. Even today, despite the rise of modern alternatives, ribbon microphones continue to hold their place in studios due to their fidelity and vintage charm. Engineers often choose them when the goal is to deliver a rich, smooth tone that closely mirrors the original performance.
However, these microphones require careful handling. Their delicate ribbon elements can get damaged by strong gusts of air or phantom power, which most condenser microphones rely on. For this reason, users must operate them with precision and protect them from mechanical shock or high sound pressure.
In summary, a velocity microphone stands out due to its refined sound capture and classic engineering. Known commonly as a ribbon microphone, it continues to be an essential tool in the arsenal of sound professionals committed to audio excellence.
