Questions about the BOLDfonic?

 

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. 

Guide price includes a desktop microphone and speakers, plus one pair of headphones and the earbuds. Many options are available, so please contact us for more details.

A range of MRI compatible headphones

The circumaural, closed-back headphone is available in a number of sizes and cable routing arrangements to suit different headcoil designs (see table below). It offers superior gradient noise dampening compared to simple pneumatic, air tube solutions. Where space permits, soft, memory foam cushions can also be inserted between the head and contact points of the coil to provide even better isolation, reduce bone conduction and improve patient comfort.

A unique electro-dynamic driver uses the magnetic field of the MRI scanner to drive the headphone membrane. This results in powerful speakers with an excellent frequency response across a wide range. An additional piezoelectric driver can be fitted to some designs, which enables those headphones to be used outside the bore too.
