Omnidirectional Sound For Maximum Audio Clarity

Pandemic or not, remote work promises to be the way of the future. Some of the largest companies in the world shifted to remote work over the past few years as the COVID-19 pandemic took hold. Even though life is beginning to return to some sense of normalcy, many have become accustomed to the benefits remote work provides, including improved employee morale, higher productivity, and bottom-line savings thanks to a reduction in office space needs.

Today’s conferencing technology makes remote work a breeze. It’s just as easy to participate in a meeting when working from home as it is when you’re in the office.

Even if a company doesn’t adopt remote work, there are plenty of situations where communication takes place over a distance. Long gone are the days when a sales team flew across the country to meet with potential clients. Instead, chances are they’ll communicate via videoconference to get deals done.

Still, the success of videoconferencing depends in large part on the equipment being used. And when it comes to group meetings, that starts with an omnidirectional microphone for maximum audio quality.

Omnidirectional vs. unidirectional

When it comes to microphones, there are two main types: omnidirectional and unidirectional. The prefix “omni” comes from the Latin word for all, such as in omnipresent (present everywhere) or omnipotent (all-powerful). The prefix “uni” comes from the Latin word for one, such as unicycle (a bike with a single wheel) or uniform (a single type or style).

Omnidirectional microphones perform just as the name implies, picking up sound from all directions, while unidirectional microphones mainly pick up sound that is directly in front of them.

And while there are situations where a unidirectional microphone is preferable, for group meetings an omnidirectional microphone is the better choice.

Advantages of omnidirectional microphones

The main advantage of using an omnidirectional microphone for group meetings is obvious: it enables all participants in the meeting to be heard clearly. The microphone can be placed on a table, at the front of the room, or even hung from the ceiling, and it will pick up participants’ voices no matter where they may be sitting or standing.

Omnidirectional microphones can also help minimize the proximity effect. The proximity effect refers to the additional bass a microphone tends to pick up if the speaker is close to the mic. And on the rare occasion they’re used outside, omnidirectional microphones can minimize wind noise.

The only real disadvantage of an omnidirectional mic in a group meeting is their tendency to pick up unwanted background noise. In a conference room or huddle space, though, that’s not likely to be an issue.

Choosing the right omnidirectional microphone

As with anything, the choice of omnidirectional microphone will be determined mainly by how it will be used. Yamaha Unified Communications, for example, offers three main types of omnidirectional microphones, each designed for different settings.

Yamaha UC’s YVC-1000MS, for example, is a great option for those just getting started in conference room audio. The YVC-1000MS features a speaker unit and the ability to daisy chain up to 5 smart microphone pods (3 mics per pod), along with connections to easily add external speakers and additional microphones.

The RM-CG ceiling-mount microphone array includes dynamic beam tracking technology that utilizes four beams to automatically track voices within the room simultaneously. Technologies within the microphone include Adaptive Echo Cancellation, Automatic Gain Control, Noise Reduction, and Dereverberation to help create top-quality audio. The RM-CG is Dante-enabled, meaning it can transmit audio over Ethernet cables with perfect fidelity.

Additionally, part of Yamaha UC’s ADECIA solution family includes the ADECIA Tabletop Microphone & Line Array Speaker Solution, which can automatically detect all components of the system and optimize them for the room environment, accounting for the location of speakers and microphones, reverberation, and echo behavior. Installation of the wired tabletop microphones is done through a LAN cable to the PoE switch. Up to 14 microphone pods (four microphones per pod) can be added for scalability.
