WHAT IS A SOUND FIELD SYSTEM?
"Sound-field is one of the most cost effective interventions a
school can invest in to increase literacy outcomes." (1)
A Sound Field System consists of one or more microphones connected wirelessly to one or more speakers. It is a public address (PA) system suitable for use in classrooms, meeting spaces, training rooms, halls, aged care, and clubs. The user's voice is amplifed over the speaker to achieve a favourable Signal to Noise Ratio (SNR) across the room.
In an education setting, many studies have proven Sound Field Systems to raise learning and literacy outcomes, create improved classroom harmony and student behaviour, whilst reducing voice strain and fatigue among teachers (1).

THE DYNAMIC DIFFERENCE OF PHONAK ROGER SOUND FIELD
- The PHONAK ROGER Sound Field System utilises one or more wireless Touchscreen microphones connected to one or more Digimaster tower speakers. The PHONAK ROGER Sound Field System is not a traditional system. Traditional systems have a fixed gain, ie the volume of amplification is set at one level, and must be adjusted manually. So, if the classroom is quiet, the teachers voice may be too loud; if the classroom is loud, the teachers voice may be too quiet. The teacher will need to manually adjust the volume of the speaker regularly to maintain favourable SNR. Most traditional systems have gain controls at the speaker, so regular adjustment is cumbersome. The teacher will also be guessing what volume level to set the system at to achieve a favourable SNR.
- The PHONAK ROGER Sound Field System operates on a dynamic or adaptive gain principle. The PHONAK ROGER SF Touchscreen microphone is worn around the teacher's neck and continually samples the ambient noise level in the room, then automatically adjusts the volume of the voice through the speaker to give a favourable SNR. When ambient noise is low, the system volume is lowered to the correct level of SNR, but as ambient noise increaeses, the system volume increases incrementally to maintain the favourable SNR, as demonstrated in the diagram below. The system is truely set and forget.

OTHER FEATURES OF pHONAK ROGER SOUNDFIELD SYSTEMS

The PHONAK ROGER SF TOUCHSCREEN MIC and DIGIMASTER speaker can also:- Be paired with further PHONAK ROGER SF TOUCHSCREEN MIC's (or other mics as below) to allow up to 35 microphones on the network.- Send the teachers voice and any sound source plugged into the multimedia hub directly to a student's ROGER FOCUS receivers. ROGER FOCUS receivers are similar to hearing aids, but only amplify the teachers voice. They are ideal for children with ASD (Autism Spectrum Disorder), APD (Auditory Processing Disorder) and UHL (Unilateral Hearing Loss). ROGER FOCUS receivers are available through assessment with an Audiologist. Click here for more info on ROGER FOCUS. - Be paired with ROGER PASS AROUND microphones, so other students can have their voices amplified.- Be paired with the ROGER MULTIMEDIA HUB to allow TV's, smartboards, computers etc to broadcast over the speaker with the teachers voice.- Be paired with ROGER REPEATER for applications where an increased range is required between the Mics and speaker.- Be used with the PHONAK ROGER BOOM MIC for even clearer voice amplification. - Be used as a Bluetooth speaker, with the teachers voice also amplified through the speaker.

The PHONAK ROGER TOUCHSCREEN v3 MIC can do everything the SF Mic can do, and also:- Send the microphone users voice and any sound source plugged into the multimedia hub directly to Phonak hearing aids, cochlear implants (CI), and bone anchored hearing aids (BAHA). - Be paired with PHONAK ROGER NECKLOOP which is worn around the neck of the aided listener, and allows any telecoil-enabled hearing aid of any brand to become a receiver of the signal from the Touchscreen Mic.- Be paired with ROGER WALLPILOT. This is a box fixed to the wall at the entry point of a room that contains a Phonak Sound Field System and allows automatic connection of hearing devices and PHONAK ROGER Microphones to the room's network.
