Collaboration spaces

A brief guide to audio in higher education

Distance learning is increasingly important in higher education, highlighting the need for high-quality audio conferencing. But collaboration spaces pose a range of problems, such as achieving adequate pickup in a room where furniture and display configurations may change and participants move about the space. Learn how the leading approaches to audio conferencing for these spaces stack up when it comes to pickup, aesthetics, installation, price and more.

Option A: Multicomponent systems

May include: Podium, headset or lapel mic for the instructor, ceiling mic arrays, hanging mics or distributed mics for students, DSP, amplifier, mixing board, cables and speakers. Components are typically sourced from a single supplier.

Audio pickup

The green circles show approximate voice pickup zones when hanging mics are deployed. It could be difficult for remote participants to hear in-room participants moving outside the circles. Reconfiguring tables, chairs and displays could also result in dead zones with restricted pickup.

Pickup

Instructor: This approach may rely on ceiling mics or use separate podium or lapel mics. Student: Common solutions are in-ceiling beamforming mic arrays or hanging omnidirectional mics. It may also use desktop omnidirectional mics.

Installation

Installing a multicomponent system may be intrusive, including ceiling renovations to build in mics and run cables. These procedures may entail expenses for hardware, technicians and carpenters, and may make the space unavailable for days.

Aesthetics

Installed in-ceiling systems can bring a polished premium look (with a price to match). Hanging omnidirectional microphones are relatively unobtrusive. Desktop omnidirectional microphones and cables can cause clutter and potential hazards.

Calibration and mixing

Many collaboration spaces are reconfigurable to suit a range of learning styles, from lectures to group work. This can be a challenge for traditional multicomponent systems because they must be recalibrated (usually by a technician) each time the room is reconfigured.

Performance

A properly calibrated and mixed system can provide professional grade audio performance. However, performance can be diminished if participants talk away from their microphones or leave the prescribed pickup zones to move about the room or work at displays.

Value

Prices for hardware and installation of traditional multicomponent systems vary widely, but they can be as high as tens of thousands of dollars. Institutions choosing this option should be sure to budget for ongoing maintenance and calibration (many providers offer service plans).

Option B: Virtual microphone system

Includes: Two wall-mounted integrated microphone and speaker bars, cables and connect module connected to a UC&C-equipped computer.

Audio pickup

The HDL300 system employing virtual microphones provides true full-room pickup. In-room participants can be heard by remote participants from anywhere in the room.

Pickup

There is no need for external microphones for the instructor or students. The Dual HDL300 system’s virtual microphones provide true full-room pickup throughout spaces up to 30' x 50' (9.14 x 15.24 m).

Installation

The Dual HDL300 system’s two integrated microphone and speaker bars can be installed on the wall in less than 60 minutes. Installation is minimally invasive and no specialized technicians are required.

Aesthetics

The two 60" x 5.9" (152.4 x 15 cm) wall-mounted units are sleek and unobtrusive. They are available in black or white to suit virtually any decor. External microphones and speakers are not required.

Calibration and mixing

Calibration is automatic and continuous for any room configuration. The Nureva Room Manager extension enables adjustment of audio levels and integration with external speakers. It also upgrades the system through automatic firmware updates.

Performance

Provides professional grade performance. Thanks to its Microphone Mist™ technology, the Dual HDL300 enables true full-room pickup that may exceed the coverage of traditional systems, allowing for more dynamic meetings.

Value

The hardware cost for the Dual HDL300 system is a fraction of most multicomponent systems. There are also significant savings on installation and setup as the system can be easily installed by in-house personnel, and calibration is automatic.
