Amma Ateria is a Hong Kong-born electroacoustic composer and sound artist working in California and New York. Her work explores the coexistence of polarity, psychoacoustics in binaural beats, and equal-loudness contour. With the immediacy of tension and release, she navigates between oppositions, transforming deafening noise into meditative stance. Her compositions, developed during recovery from a concussion, utilize brainwave entrainment, time shifts, and changes of neurological responses to DELTA, THETA, ALPHA, BETA, GAMMA waves as their materials and focal point. With memories of condensed cities, she gravitates towards frequencies of close-ranged airplanes, polyrhythmic occurrences, out-of-body experiences, sustained harmonics intersected with musique concrète, and distorted speech as lost speech.
