This innovative device features a dynamic noise modulation system that transitions between ANC and transparency modes, tailored to the acoustic needs of patient rooms, operating theatres, ICUs, and dental practices. It is designed for use in sleep laboratories to enhance rest and in audiometry rooms for precise auditory assessments. The portable and cost-effective design eliminates the need for traditional acoustic modifications. Post-ear surgery patients benefit from its calming auditory settings, while pediatric care is supported through its soothing properties. Its versatility extends to diagnostic imaging and recovery rooms, ensuring tranquil environments. Beyond healthcare, this ANC headphone has potential therapeutic applications, including vestibular rehabilitation, by supporting the recovery of the villi in semicircular canals. Its adaptability across environments such as libraries, mining, production industries, theatres, and urban noise landscapes highlights its broad utility. Although the ANC circuitry has been carefully designed, empirical validation is still pending. This manuscript explores the headphone’s diverse applications and its ability to transform noise management and auditory health across multiple domains. Tailored modes for specific scenarios, including traffic noise, emphasize its innovative potential as a key tool in auditory technology.展开更多

To ad- dress this problem, we propose an effective sound image externalization approach. Specifically, we consider several important factors related to sound propagation, which include image-source model based early reflections with distance decay, wall absorption and air absorption, late reverberation and other dynamic factors like head movement. We apply our sound image externalization approach to a headphone based real-time 3D audio system. Subjective listening tests show that the sound image externalization performance is significantly improved and the sound source direction is preserved as well. A/B preference test further shows that, as compared with a recent popular approach, the proposed approach is mostly preferred by the listeners.展开更多
