Lightspeed™ Classroom SoundField Systems

Clearer Classroom Audio for Teaching and Learning

Background noise, distance and room acoustics can make it harder for students to follow spoken instruction.


Lightspeed™ classroom SoundField systems use a wireless teacher microphone and classroom speakers to distribute speech throughout the learning space. They help make the teacher’s voice easier to hear while supporting a comfortable, natural speaking level. Suitable connections and accessories also allow audio from computers and other teaching resources to be shared through the system.


Hear Room provides independent advice, supply, system design, commissioning, training and ongoing support. We help schools choose and use a Lightspeed system suited to their classrooms, teaching practices and students’ listening needs.

why classroom audio matters

Why Classroom Audio Matters

Clear access to spoken instructions, explanations and discussions is an important part of classroom learning. When speech is difficult to hear, students may miss information or need to work harder to follow what is being said.


Lightspeed™ classroom audio systems help distribute the teacher’s voice across the learning space, supporting more consistent access to speech and helping teachers communicate at a comfortable speaking level.


Good classroom listening also depends on room acoustics, background noise and individual student needs. Hear Room considers these factors when recommending and setting up a system, helping schools take a practical approach to improving listening conditions.

Common Classroom Listening Challenges

Background Noise

Air conditioning, projectors, hallway activity, neighbouring classrooms and student collaboration all contribute to background noise that competes with the teacher's voice.


Distance from the Teacher

Speech naturally becomes quieter as students move further away from the teacher. Students seated at the back or sides of the classroom may hear significantly less clearly than those seated at the front.


Classroom Acoustics

Hard surfaces such as concrete floors, glass and plasterboard reflect sound, creating reverberation that reduces speech intelligibility.


Teacher Voice Fatigue

Teachers often raise their voices throughout the day to ensure every student can hear. Over time, this can lead to vocal fatigue, discomfort and increased strain.

Good classroom audio supports clear speech at a comfortable listening level.

Hear Room assesses room acoustics, room size, teaching practices and students’ listening needs to recommend a suitable classroom audio system. Explore the Lightspeed options below, or contact us for advice on your learning space.

Classroom SoundField FAQs

A classroom SoundField system distributes speech through speakers around the room. A personal microphone system sends speech to a student’s compatible hearing device or receiver. A student may need both. Hear Room checks the student’s listening needs and how the systems can work together.

A SoundField system distributes speech, but background noise and reverberation still need attention. Hear Room considers the room’s acoustics, layout and teaching activities when recommending a system.
