This image depicts a retroreflective dome that I designed and constructed. The dome’s geometry is precisely engineered to reflect sound directly back to its source, creating a unique and immersive auditory environment for performers. Below, you will find audio files of cello improvisations recorded within this dome. The recordings were captured binaurally at my ear positions, offering a highly realistic and spatially detailed listening experience that closely mirrors what a performer would hear inside the structure. In addition to its artistic applications, this dome has been utilised in acoustics research as a specialised reflector, enabling individuals to hear themselves more clearly in environments with multiple simultaneous speakers.
