Summary

The presenter demonstrates how to use a handheld directional microphone, using a Shure SM58 as an example, to get a clearer, more controlled vocal sound and avoid problems for the sound engineer. The two main factors are how the microphone is held and how far it is from the mouth.

Handling the microphone

• Don’t hit or tap it to test it. Impacts can cause loud pops and may damage equipment, particularly more delicate or expensive microphones. Instead, speak normally and ask the engineer to confirm that the signal is coming through.
• Hold the handle, not the grille. The grille and the openings around the microphone head are part of its acoustic design. Covering them changes how the microphone picks up sound.
• Avoid cupping or enclosing the microphone head. Covering its side or rear openings can alter its directionality and tone, making the sound muffled, boomy, or “honky.” It can also increase the level of unwanted sound and feedback from stage monitors.
• Keep the side openings clear if using a stylized grip. The presenter demonstrates holding the microphone with the thumb and index finger while leaving the sides open. If you intentionally want a cupped-microphone effect, tell the engineer.

Using distance to shape tone and volume

• Move closer to a directional microphone to increase bass through the proximity effect, creating a fuller, warmer sound. Speaking or singing softly at close range can make the voice sound rich.
• Move farther away to reduce bass relative to mid- and high frequencies. This can make a voice sound clearer or less heavy, though it may make a harsh voice seem thinner.
• Choose a distance that suits the voice and desired sound rather than keeping the microphone at a fixed distance.

Distance also strongly affects loudness. Moving the microphone closer can make the voice much louder without requiring more vocal effort. Under ideal conditions, halving the distance can produce roughly a 6 dB increase. Adjusting microphone distance may therefore help more than simply asking for more volume or monitor level.

Overall lesson

A microphone’s sound is affected by its pickup pattern, the openings around its grille, and its distance from the sound source. Keep the grille unobstructed, avoid impact-testing, and use distance deliberately to manage both tone and volume.
