The Sound Museum, nestled on Baizhang Lake in Yaan, reconnects the community and nature through sound. Inspired by the concept of The Earths Sound Bowl, the architecture emerges from the land as if it were a natural instrument. By harnessing the reflective and propagative properties of sound, we designed dual acoustic pathwaysone converging inward and the other radiating outward. This allows the building to achieve unique sonic effects while using sound as a medium to interconnect its various spaces. The project consists of three primary components: the Sky Theater, the Outdoor Theater, and the Earth Theater. In the Outdoor Theater, acoustic reflections enable visitors to hear performances from the Sky Theater, as well as sounds from the Earth Theater transmitted through gaps. The Earth Theater serves as a meditative space when not in use for performancesvisually isolated from the outside world, yet permeable to natural sounds through strategic openings. During performances, it transforms into a unique acoustic environment. The Sky Theater is an expansive performance space that opens toward the sky and the lake. Functioning as a "sound bowl," it captures the subtle orchestra of the site: the patter of rain, the whisper of wind through reedsframing these natural rhythms for mindful listening. During non-performance hours, the Sound Museum itself becomes an instrument, using sound to encourage spontaneous encounters and interactions among diverse visitors. The buildings materiality reinterprets local terrazzo craftsmanship, with surfaces finished to varying degrees of roughness to either reflect or absorb sound. Through the medium of sound, the Sound Museum seeks to redefine the relationships between people and nature. Innovatively organized through meticulous sectional studies, the building functions as a perforated instrument that absorbs both human and natural sounds. As time flows and nature shifts, a continuous symphony unfolds within its spaces.
