With parallels to that giant, concrete speaker in Taiwan, photographer Piercarlo Quecchia has tracked down all of Britain’s remaining strange and sculptural sound mirrors, built after World War 1 to detect incoming enemy aeroplanes.
Acoustic defense: photo series reflects on derelict British “sound mirrors”
“They represent an incredible demonstration of how sound can generate a physical form: both the curvature radius and the dimensions of the dishes are studied and designed according to the sound frequency that they must reflect,” explains the photographer. He hopes the series will continue to raise awareness of these artifacts.
There are more images of these brutalist-looking structures on his website.
Sound Mirrors’ Portraits – Piercarlo Quecchia
They consist of concrete parabolas with a diameter of a few meters. In the twenties of the last century, their use combined with microphones, allowed to intercept planes directed towards the coast, discovering in advance any possible attacks. The need to be positioned near the coasts mainly in raised areas, the strong materiality of the concrete and their huge dimensions make them spectacular and extremely fascinating structures, able to dominate the entire surrounding landscape.
