Measurement microphones are generally scalar sensors of pressure; they exhibit an omnidirectional response, limited only by the scattering profile of their physical dimensions. Sound intensity or sound power measurements require pressure-gradient measurements, which are typically made using arrays of at least two microphones, or with hot-wire anemometers.

The SR30 (same as SR77) is a remarkable cardioid that maintains most of the characteristics of our omni microphones. At 6 inches away from the source it sounds as onmi-like as a cardioid can. The off-axis rejection is substantial yet uncolored. Its iSaber más
- MBHO MBNM 550469,00 €Primarily designed for calibration purposes, the MBNM 550 ELis an electret omni with superb linearity characteristics. As it is a neutral ( + 1 or - 0 dB) microphone with response at the tip nearly matching its response at the side or back, many prefer utilizing this microphone to minimize sound balance problems while recording solo instruments or voices in the near field. The capsule easures only 6 mm and works well with voltages from 16 - 48 V. Each MBNM 550 ELmicropho-ne is supplied with an individual test chart. Saber más
