New UBSN Equipment Accessory - OptoACTIVE

Dear Staff and Students,



We are excited to announce a new equipment accessory here at UBSN - OptoACTIVE, an MRI-compatible active noise cancellation system, now located in ZB216.


OptoACTIVE™ provides the highest level of noise reduction available in MRI-safe headphones, and is the only communications system to use real-time algorithmic, active harmonic noise cancelling, as well as Optoacoustics’ proprietary passive noise reduction techniques, to reduce 60 dB (over 95%) of MR EPI main gradient resonance noise for the patient.


Ultra-slim OptoACTIVE headphones are designed for advanced 20- or 32-channel coils used in 3T and 7T fMRI. OptoACTIVE provides the slimmest and most sensitive headphones available today for use in MRI, with a frequency response range of 50-20,000 Hz. Built-in optical microphones enable automatic self-calibration, SPL monitoring and real-time in-ear stereo sound recording. With its proprietary DSP and predictive behaviour algorithms, OptoACTIVE sets the standard for robust, dependable active noise control in a wide variety of applications and settings, regardless of the MRI platform.


For enquiries, please contact our officer-in-charge: Dr. Celia DONG (
