Glossary

Equivalent noise level

The output signal of every microphone always includes a low noise signal in addition to the useful signal. In order to illustrate the extent of the noise voltage, it is given as a fictitious sound pressure level. In an ideally noise-free microphone, a sound pressure level of this magnitude would result in an output voltage of the magnitude of the noise. Self-noise is measured and weighted either in accordance with CCIR 468-3 or – in order to assimilate the measured result with the listening impression of the human ear – in accordance with DIN/IEC 651 (so-called A-weighted). Studio condenser microphones generally have an equivalent noise level of between 20 and 30 dB (CCIR) or between 10 and 20 dB(A).

Frequency response

The frequency response of a microphone is given within the limits defined by the manufacturer. In studio condenser microphones it is generally within the range of between 20 Hz and 20 kHz.

Max. sound pressure level (active)

The maximum sound pressure a unit can reproduce before a given THD is reached.

Min. terminating impedance

Impedance at which the connected unit meets the specified technical data. If the unit is connected to a lower impedance, it will usually have a lower output voltage or a greater distortion.

Nominal impedance

See impedance.

Phantom powering

Almost all studio microphones are supplied with 48V ±4V phantom power (P48, IEC 268-15). This supply voltage is applied to both modulation lines, while the return current flows via the cable screen. Some microphones can also be powered by batteries or from plug-in mains adapters.

Pick-up pattern

Also known as polar pattern, directivity. According to their acoustic design, microphones differ in their sensitivity towards sound from different directions. Pressure microphones have a sensitivity that is largely independent of direction (omni-directional pick-up pattern). Pressure gradient microphones have the pick-up patterns wide cardioid, cardioid, super-cardioid or figure-of-eight. Interference microphones can be used to achieve a further concentration of the pick-up pattern (lobar pick-up pattern). As a special case, dummy head microphones achieve the pick-up pattern of the human ear/head (dummy head stereo).

Sensitivity in free field, no load (1kHz)

Voltage measured at the unloaded output of a microphone which is exposed to a sound pressure of 1 Pa and a frequency of 1 kHz in an anechoic chamber.

Transducer principle

Two transducer principles have become established for the conversion of electric energy into mechanical energy: electrodynamic and electrostatic transducers, whereby the latter is only to be found in audiophile systems, due to their relatively high manufacturing costs. Electrodynamic transducers basically consist of a ring-shaped permanent magnet and an oscillation coil, which is fixed to the receiver diaphragm. When an audio-frequency alternating current is passed through the oscillation coil, it is caused to vibrate in accordance with the audio-frequency alternating current, thus causing the diaphragm to vibrate in the same way.
