The Roger Dynamic SoundField is a classroom amplification system featuring industry-leading sound performance combined with plug-and-play simplicity. Dynamic SoundField is a new generation soundfield technology with automated settings and a specially designed loudspeaker array for even distribution of the teacher’s voice in a classroom. Here you will find detailed documents to explain, support and reference Roger claims for excellence in dynamic soundfield with universal design.


Here is a selection of informational brochures to be educational resources about Roger SoundField.


The Roger Dynamic SoundField is a classroom amplification system featuring industry-leading sound performance combined with plug-and-play simplicity. 

Roger SoundField has the easiest to use, best researched and most user friendly products on the market. Roger speakers level to a specific signal to noise ratio - when the room is quiet, the speaker automatically reduces volume, and when noise levels increase, the speaker increases. Dynamic and intuitive. Roger works. Here’s how.

Unique ‘line source’ loudspeaker unit

Teacher Benefits

[1] 100% of teachers identified a decrease in vocal strain and fatigue as a key personal benefit of using a soundfield amplification system

[2] Teacher absences due to vocal strain and voice fatigue decreased from 15% percent to an average of 2-3% in one year (MARRS, 2005b)

[3] Aids class instruction and management

[4] Fewer discipline problems through improved voice-control of students

[5] Less stress

[6] Improved in-class mobility

The Phonak DigiMaster loudspeaker offers high directionality and creates far less problematic reverberation than any existing soundfield system. The DigiMaster transmits a clear, high-quality signal using just one or two loudspeakers per room (depending on room size). 

Fully automated settings

Roger Dynamic SoundField continually monitors and automatically adjusts its frequency and volume settings by measuring a room’s actual noise level and optimizing accordingly. It provides optimal signal-to-noise ratios (SNRs) and transforms the world’s first intelligent soundfield into a product anyone can use.

Digital sound quality

Roger Dynamic SoundField digitally transmits its signals, automatically changing frequencies when required in order to eliminate potential interference caused by a building’s existing Wi-Fi and Bluetooth networks. The system does not need to operate on a particular channel; therefore, there are no sound “dead spots.” Pairing transmitter and loudspeaker is simple, and there is no limit to the number of license-free systems that can be used on one site.

Works with interactive whiteboards and multimedia

Clients who use an interactive whiteboard or screen can simply connect their computer or multimedia device to the DigiMaster using a standard audio cable. The result is a high-performance system that intelligently amplifies its audio output to ensure listeners hear and understand everything they say. 


The Roger Dynamic SoundField system with the Roger Touchscreen Mic is the only digital classroom solution that can be used simultaneously with additional microphones and personal receivers.

Why SoundField Matters

Hearing well in a classroom setting is important for students to truly excel and have the best learning experience. Modern classrooms can make hearing challenging for children due to factors such as background noise, less than optimal room acoustics and the distance between teacher and students.

In order to overcome these everyday difficulties, sound field classroom amplification is essential. For children with Auditory Processing Disorder (APD), Attention Deficit, Hyperactivity Disorder (ADHD), and even for children learning in their non-native language, having a system which amplifies sound via a loudspeaker has been proven to enhance their listening and learning skills. This approach also means teachers don’t need to raise their voices to be heard, therefore reducing vocal strain, hoarseness and in cases of temporary voice loss, even time off work.

The New Signal Standard

Roger is a new wireless technology standard. Based on Roger, platforms and products will emerge over the coming years. This brochure describes the details of, and the reasoning behind, the Roger technology. Roger allows for low-delay and reliable broadband audio broadcast towards miniature low-power receivers, that can be connected to hearing instruments or cochlear implant sound processors, as well as towards Roger SoundField loudspeakers. Roger is much more than a simple digital radio system. Sophisticated adaptive algorithms at different levels in the Roger architecture give Roger a performance level which was not previously considered physically possible. At the same time, automatic features and simple pairing concepts make management and use of Roger systems very easy.

Improved Speech Recognition

A study by Dr. Jace Wolfe of Hearts for Hearing in Oklahoma found that a Roger Dynamic SoundField system with a single loudspeaker unit resulted in significantly better speech recognition at higher noise levels than a fixed-gain sound field system with four loudspeakers placed strategically in a classroom. Roger Dynamic SoundField is not a fixed-gain system but adjusts its volume setting automatically depending on the classroom noise level. Furthermore, the patching of a fixed-gain sound field system with the microphone unit of an adaptive (Dynamic or Roger) personal ear-level receiver system created a significant drop in performance and should therefore be avoided.

Teacher Ratings

Rina Simonchoni, Teacher, SD23, KLO Middle School, Kelowna BC:

"I was lucky to have the system because it saved me this year. I came back from work with my concussion and was working part time, it wasnít a strain to give instructions or overuse my voice. It gets the attention of the class quickly and helps them to focus. Iíve used other systems before and this is the best Iíve ever had for sure. There was one time when I was recovering from illness and couldnít get rid of my sore throat and dry cough, and it was such a saviour for that so I didnít have to strain my voice. You guys have probably made one of my most challenging years easier because of personal health issues. It saved my voice. Thank you so much for letting me use this system!"

In the study below, teachers at a primary school in New Zealand, used Roger Dynamic SoundField in their classrooms for an average of two months. They then each completed a questionnaire of 13 targeted questions with a response rate of 100%. The teachers reported a significant improvement in student performance when using Roger Dynamic SoundField, their own vocal strain was reduced, it was quieter in class, the equipment was easy to use and the sound quality was highly rated.

Why Dynamic?

Unlike traditional sound field systems with fixed-gain settings, Roger Dynamic SoundField automatically varies the volume of the system with changes in the ambient noise level. Goal of this dynamic behaviour is to improve speech intelligibility of the teacherís voice especially when noise levels increase in class, but at the same time to offer a comfortable volume during more quiet moments.

Roger Dynamic Outperforms Fixed Gain Systems

Roger Dynamic SoundField outperforms fixed gain systems, which are all other systems (Lightspeed, Front Row, Simeon). Below is a Study by Dr. Jace Wolfe to explain the benefits of the Roger Soundfield System over traditional FM and infra-red systems.
