The proximity effect in audio is an increase in bass or low frequency response when a sound source is close to a directional or cardioid microphone. [1] [2] Proximity effect is a change in the frequency response of a directional pattern microphone that results in an emphasis on lower frequencies. It is caused by the use of ports to create ...
The internal electronic circuitry of an active noise-canceling mic attempts to subtract noise signal from the primary microphone. The circuit may employ passive or active noise canceling techniques to filter out the noise, producing an output signal that has a lower noise floor and a higher signal-to-noise ratio .
Like all directional microphones, the SM58 is subject to proximity effect, a low-frequency boost when used close to the source. The cardioid response reduces pickup from the side and rear, helping to avoid feedback onstage. There are wired (with and without on/off switch) and wireless versions.
At a distance of about 50 cm (0.5 m) the time delay for a signal reaching first one and then the other microphone from the side is approximately 1.5 ms (1 to 2 ms). If the distance is increased between the microphones it effectively decreases the pickup angle.
In 2024, Sennheiser introduced a smaller version: the MD 421 Kompakt model. The microphone is intended for tight locations such as a drum kit or in front of a guitar amplifier on a small stage. Its new swivel clip is integral to the microphone, not removable. A drum clamp is available as the MZH model. [12]
An infrared proximity sensor Optical proximity sensor in a 2016 Samsung smartphone.A proximity sensor is a standard feature of most smartphones, disabling the touchscreen when positioned near an ear during phone calls; more recent (late 2019-early 2020) smartphones with OLED displays may have the sensor mounted under the display.
The large size and weight of the RE20 requires a strong microphone stand or boom arm, and a very sturdy microphone clip or robust hanging yoke. The supplied mic clip (model number 320) is tightened securely with a knurled knob. An optional shock-mount is available for the RE20 family of microphones: the EV model 309A.
