![]() A simulation tool was developed enabling researchers to explore the effects of electrical stimulation on the temporal pattern of nerve impulses generated by CIs and, from this, to develop computer models of neural sensitivity to binaural electrical stimulation. Software processing can be changed on the fly. The new platform is well suited to assessing sensitivity to binaural spatial cues, including interaural time differences (ITDs), in real-time, and supports instantaneously variable stimulation rates. A crucial aspect of this research platform lies in its use of the Master Hearing Aid (MHA) technology of Hörtech, the hearing technologies centre allied to Oldenburg Univerity. In order to provide CI researchers with the tools necessary to assess binaural function, a portable, real-time research platform was developed, capable of processing signals from 4 microphones simultaneously. Critical aspects of the programme were to ensure the successful delivery of the milestones and deliverables within each WP, and to ensure compatibility across WPs. The programme of work was divided into six work packages (WPs), each with a named lead partner. The aim of this programme, Advancing Binaural Cochlear Implant Technology (ABCIT), therefore, was to develop a framework in which binaural hearing was central to the function of CI technology. ![]() Bilateral cochlear implantees (most children born deaf and an increasing number of adult recipients) are fitted with essentially two independent devices, each without regard to the sound processing or electrical stimulation of the other ear. Compared to normal-hearing individuals, users of cochlear implants (CIs) are at a disadvantage when facing binaural tasks. Binaural (two-eared) hearing is critical for localizing the source of a sound, and for hearing out conversations in background noise (cocktail party listening). This makes the 3DIO binaural microphones ideal for applications such as 360 and 180 VR video and any professional recording situation where authentic sound quality is critical.Executive Summary: 1.0Ğxecutive Summary In 2012, a consortium of researchers and commercial partners in the UK, France and Germany secured €4M from the European Union’s ‘Framework 7’ research fund to develop a research programme aimed at progressing bilateral cochlear implantation towards true binaural performance. ![]() When listening to binaural recordings with headphones, a natural three-dimensional sound gives the listener the sensation of being in the space where the audio was recorded. Furthermore, the time delay between the left and right ear gives us proper directional perception. These ears (pinnae) dramatically alter the incoming sound waves, however the human brain understands and interprets these alterations as directional cues. Binaural recording is the process using microphones shaped like human ears to capture audio in the same way that we hear. It also prevents any harsh effects sometimes associated with binaural recordings using smaller capsules.ģDIO manufacture premium quality 3D audio recording devices that are popular with professional recording engineers as well as amateur enthusiasts. drum cymbals or strummed acoustic guitars. The frequency response of the EM172 capsules rolls off slightly above 10kHz making them excellent for recording instruments with loud high frequencies e.g. The 3Dio Free Space has a very warm and solid response in low to mid-range frequencies and also provides low-end support for bass-heavy sounds. This allows users to capture sound just as we would naturally hear it and enable you to pinpoint the sound location in space. The 3Dio Free Space binaural microphone is an affordable, high-quality binaural microphone comprising Primo EM172 microphone capsules embedded inside two prosthetic ears.
