Audio and communication systems are often an understated workhorse in schools; when they function well, most staff, students and whānau don’t think much about them day-to-day.
However, when something goes wrong – whether that’s technical problems from aging infrastructure, volume issues with a PA system at a school sports day, or even in an emergency – everyone notices.
In a nutshell
Evaluating your existing audio and communication systems and identifying any shortcomings can help to head off any issues before they become troublesome, and with next-generation smart audio systems, there are bound to be options that suit every setting and scenario.
Modern systems rely on IP paging, rather than analogue wiring; simply put, they transmit via the same internet connection used for a school’s wifi. IP communication allows much greater flexibility, including easier installation and more options around uses, placement and customisation.
Benefits of IP systems
Today’s communication systems offer access to a host of features that older ones cannot provide, such as integrating speakers, clocks, bells and emergency systems to create an ecosystem that removes redundancy and is simpler to use.
Another major benefit is that many systems offer zoning and scheduling that work together. If older students work on a different timetable to younger ones, for example, then bells, reminders and other messages can play at the correct times for each zone. It also means that announcements don’t need to interrupt classrooms where they are not relevant.
Emergency management
In an emergency, the seamless integration and smart features of an integrated classroom system come into their own. In weather events, fires and lockdowns, instant, targeted messaging can make all the difference. Systems can also be customised with digital displays to deliver messages to students and staff who cannot hear them.
Pre-recorded messages can also be utilised in emergency scenarios, so key points including safety information and muster areas can be given automatically, freeing up main personnel for other time critical tasks.
With so many possibilities for schools, from integrating new technology into old systems to starting over with a bespoke layout, School News talked to the experts about what to consider when implementing a smart communications system.
Schools are busy places, and clear, concise messaging, that can be delivered flexibly, is essential. In what ways are modern IP paging and PA systems assisting schools with this?
Euan Mackenzie, NAS New Zealand: Clear, reliable communication is important for any well-functioning school, but it’s usually only appreciated when something goes wrong. Recent developments in AV technology are helping schools move beyond clunky ‘sticky-plastered’ systems toward integrated, communication networks that are simple to use, flexible and most importantly dependable.
Couple this type of backend with carefully chosen modern speaker designs and audio systems can deliver consistent, intelligible messaging across classrooms, outdoor spaces, and shared facilities, ensuring that everyday announcements, timetable changes, and pastoral communications are heard clearly by the entire school (and not the neighbours).
One of the most significant shifts has been the move toward networked audio which allows these systems to converge with existing data infrastructure.
Schools can now manage announcements centrally while still allowing for zoned or localised messaging. This reduces disruption, improves clarity, and supports more tailored communication, whether that’s a reminder to a single block or a full-school assembly call.
Just as importantly, these systems are becoming easier to use, meaning staff can act quickly and confidently without needing technical expertise.
Modern sound systems support schools during emergencies by enabling clear, campus-wide communication—explain the benefits they provide in these situations.
Euan Mackenzie: In critical situations such as severe weather events or lockdowns, the difference a well-designed sound system makes cannot be overstated. Clear, immediate instructions reduce confusion and help maintain calm, which is essential for both student safety and staff response. In these moments, communication must be instant, unambiguous, and audible in every corner of the school.
Ultimately, investing in thoughtful, future-proofed audio infrastructure is not just about convenience, it’s about creating an environment where communication supports both learning and safety every day.
What are some factors that schools should consider when hiring, upgrading or replacing audio or communication networks?
Euan Mackenzie: Schools sometimes underestimate the importance of sound intelligibility over sheer volume. A loud system is not necessarily an effective one.
Factors such as speaker placement, background noise, building acoustics, and even future campus expansion all play a role in whether a message is understood.
Resilience is another often overlooked consideration. Systems need backup power and redundancy to remain operational during outages or emergencies.
