Lightspeed™ Classroom SoundField Systems

Clearer Voices. Better Learning.

Every classroom presents listening challenges. Background noise, distance from the teacher and poor acoustics can reduce speech understanding for every student.


Lightspeed™ SoundField systems distribute the teacher's voice evenly throughout the classroom, creating an environment where every learner can hear clearly, participate confidently and stay engaged.


Hear Room provides independent advice, system design, commissioning and ongoing support to help schools achieve the best possible listening environments.

Why Classroom Audio Matters

Every Student Deserves to Hear Clearly

A classroom is one of the most important listening environments a child will experience. From the first lesson of the day to the final classroom discussion, students rely on hearing clearly to follow instructions, participate in conversations and build new knowledge.

Research consistently shows that spoken communication forms the foundation of classroom learning. Yet even in modern classrooms, background noise, distance from the teacher and room acoustics can reduce speech clarity, making it harder for students to stay engaged and understand what is being taught.

For many students, listening is not effortless—it requires significant concentration. The more energy they spend trying to hear, the less energy they have available for learning.

Lightspeed™ SoundField systems help overcome these everyday listening challenges by distributing the teacher's voice evenly throughout the classroom, giving every student clearer access to instruction, regardless of where they are seated.

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 listening isn't about making the teacher louder—it's about making speech clearer.

Hear Room, we assess each learning space independently to ensure the right classroom audio solution supports both teaching and learning. By considering acoustics, room size, teaching style and student needs, we help schools create environments where every voice can be heard and every learner has the opportunity to succeed.
