Cambridge Research Systems' team is proud to introduce BOLDfonic, an integrated, single-source solution for calibrated audio.

Looking for a calibrated audio solution for 3T and 7T fMRI?

BOLDfonic delivers high-fidelity acoustic stimuli for fMRI while also attenuating scanner noise.

Our electro-dynamic driver technology uses the magnetic field of the MRI scanner to drive the headphone membranes. This results in powerful speakers with an excellent frequency response across a wide dynamic range. A novel USB sound processor with automated synchronous triggering capabilities and a fully–loaded amplifier system provide all the controls you need for rigorous multimodal EEG/fMRI studies.

BOLDfonic integrates perfectly with our LCD monitor system, eye tracker and the other Made for fMRI devices from our range
