A brick wall of sound was a sound installtion for the windows at Ny Musikk's offices in Oslo in autumn 2005.
The offices were at street level with large storefront windows. Transducers was placed inside on the window surface, making the sound emit from the window surface. A large picture of a brick wall covered the windows. A tapping sound was heard when you walked past the window, to get attention. The passersby could trigger the sounds by touching special places on the glass.
