A hyper-cardioid microphone is similar to cardioid, but with a slightly larger figure-8 contribution, leading to a tighter area of front sensitivity and a smaller lobe of rear sensitivity. It is produced by combining the two components in a 3:1 ratio, producing nulls at 109.5°. This ratio maximizes the directivity factor (or directivity index). [51] [52] Estreich, Bob.

While you can find some inexpensive options, the nice touch screen phones that have all the bells and whistles can start to rise in cost, making them a bit less comparable than other options at the price point.

The quality of the sound should be really fine. You should make sure that you are buying a reliable and quality mic that provides 360-degrees omnidirectional sound quality.

If your conference room has some high ceilings, then a hanging microphone might be necessary to ensure it will catch every voice in the room. Even going beyond just the room layout, your team might have some specific audio requirements for their hardware. Some setups might allow users to mute their mics, but others might just be one single mic and muting would mean cutting out everyone. Other directional patterns are produced by enclosing one side of the ribbon in an acoustic trap or baffle, allowing sound to reach only one side. The classic RCA Type 77-DX microphone has several externally adjustable positions of the internal baffle, allowing the selection of several response patterns ranging from "figure-eight" to "unidirectional". Such older ribbon microphones, some of which still provide high-quality sound reproduction, were once valued for this reason, but a good low-frequency response could be obtained only when the ribbon was suspended very loosely, which made them relatively fragile. Modern ribbon materials, including new nanomaterials, [27] have now been introduced that eliminate those concerns and even improve the effective dynamic range of ribbon microphones at low frequencies. Protective wind screens can reduce the danger of damaging a vintage ribbon, and also reduce plosive artifacts in the recording. Properly designed wind screens produce negligible treble attenuation. In common with other classes of dynamic microphone, ribbon microphones do not require phantom power; in fact, this voltage can damage some older ribbon microphones. Some new modern ribbon microphone designs incorporate a preamplifier and, therefore, do require phantom power, and circuits of modern passive ribbon microphones (i.e. those without the aforementioned preamplifier) are specifically designed to resist damage to the ribbon and transformer by phantom power. Also there are new ribbon materials available that are immune to wind blasts and phantom power. A valve microphone is a condenser microphone that uses a vacuum tube (valve) amplifier. [25] They remain popular with enthusiasts of tube sound. Systems for extracting voice input from ambient noise (notably telephones, speech recognition systems, hearing aids)
