More Sound.
Less Noise.

Introduction

Quality audio solutions for the MR environment are hard to find. Low quality audio results in a very poor patient experience. It can severely limit communication between patient and operator, limit the effectiveness of entertainment solutions, and restrict the ability to transmit audible stimuli for functional MRI.

Introducing nordicAudio.
An MR-compatible audio system that brings quality sound to the MR environment.

Key features

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.

Slim design

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.

Fibre-optical connection

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.

Test data

Frequency response

nordicAudio scores 85% on the Harman preference rating model (I.e., very good). The Harman Target represents “neutral” sound, where all frequency ranges are perceived as equally loud.

For reference, Bose QC 25 scores 77%*.
