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