IntroducingnordicAudio. An MR-compatible audio system that brings quality sound to the MR environment.
30dB SNR noise reduction
In addition to the passive noise attenuation provided by the headphones, the real-time active noise cancellation based on destructive interference of the perceived sound from the MR scanner provides a level of sophistication which is greater than other solutions on the market.
Innovative speaker technology
The latest Microelectromechanical Systems (MEMS) technology has been used in an innovative design to provide exquisite sound quality, which can compete with the best off-the-shelf personal headphones on the market.
Unlike many other headphones used in the MR environment, the slim design allows the subject to wear this headset inside some of the most confined head coils available for advanced neuroimaging.
Easy-to-use and comfortable
Like all of our products, we strive for ease-of-use and ergonomic design, as well as providing a comfortable experience for the subject even in a restricted space.
Latency is an important consideration in functional MRI. With a direct connection via optical fibre, the potential delay in transmission of audio stimuli is minimized.
Retain excellent image quality
The headset design uses specially selected materials to avoid artefacts in the MR images, even when scanning the brain.
Slim headphones that are designed to fit perfectly in most head coils.
