Inmergo is a novel and patent-pending audio technology which inventive step is to avail of optimised liquids and gels as sound mediums. It generates an omnidirectional surround effect and gives richness and vibrotactile feedback to the low-end enhancing a more immersive perception of sound. It has also been proven to be a successful form of Hi-Fi audio solution inclusive to people suffering from hearing loss or dysfunction in the middle and outer ear or with cochlear implants, being awarded the Helen and Hamlyn Design Award 2019 for Disability. Inmergo has born as research on human hearing capabilities, particularly inspired by recent design efforts on bone conduction technology. This has been associated mainly with devices who are meant to let the user hear outer sound while simultaneously listening to music, at the expense of sound quality. Inmergo aims then to reimagine and reinvent bone-conduction from being a low-quality technology to a hi-fi enhancement with a much larger valuable impact range and applications. The project has been supported by several consultations and institutions such as Imperial College, UCL Ear Institute, NHS, Action on Hearing Loss and Goldsmiths Music Mind and Brain. This helped to define quantitative acoustic analysis and qualitative user testing donating wonder, joy and relaxation to more than 20 subjects including a deaf person with a unilateral cochlear implant which defined it as one of the best listening experiences of her life. A flexible membrane is designed to comfortably adapt to different anthropometrics, guaranteeing a better sound transmission, while the driver is stabilised within the rigid cabinet submerged into the fluid, at the right distance from the ear, and simultaneously acting as a natural sound cancelling medium. I have then realised and exhibited a 2-units portable headphone and a 5-units sensory helmet which represent the highest achievement of this fluid conduction technology.
