Amma Ateria is an electroacoustic composer and sound artist born in Hong Kong, works in California and New York. Her work explores themes in the coexistence of polarity, psychoacoustics in binaural beats, and equal-loudness contour. With immediacy of tension / release, her performances navigate between stark oppositions, transforming deafening noise into meditative stance. Through cross-modal synesthetic influences from the contemporary moment, notions of externalizing resonances act in forms of questioning boundaries  via the sonic spectrum. Her research focuses on objective / subjective perceptions of sound pressure level through velocity simulation, noise colours in electronic synthesis, and behavioral assignments with multi-channel systems. Her compositions developed during concussion recovery utilizes brainwave entrainment, time shifts, and changes of neurological responses to DELTA, THETA, ALPHA, BETA, GAMMA waves as materials and focal point. 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.
