Instrument des Tages (140): Ein vereister See

Der Berliner Komponist und Klangkünstler Andreas Bick hat einen gefrorenen See in der Nähe von Berlin aufgenommen. Schwankungen der Umgebungstemperatur veranlassen gefrorene Seen dazu, richtig laut zu werden. Wenn das Eis sich ausdehnt oder zusammenzieht, werden die daraus resultierenden Spannungen hörbar. Die besten Zeiten, um einem gefrorenen See zuzuhören, sind der frühe Morgen und der Abend.

Hier die Klänge des gefrorenen Sees. ♫

Andreas Bick über die eisige Klangwelt:

“In my experience, thin ice is especially interesting for acoustic phenomena; it is more elastic and sounds are propagated better across the surface. Snowfall, on the other hand, has a muffling effect and the sound can only travel to a limited extent. The ice sheet acts as a huge membrane across which the cracking and popping sounds spread.

Underwater microphones proved especially well-suited for these recordings: in a small hole drilled close beneath the surface of the water, the sounds emitted by the body of ice carry particularly well. The most striking thing about these recordings is the synthetic-sounding descending tones caused by the phenomenon of the dispersion of sound waves. The high frequencies of the popping and cracking noises are transmitted faster by the ice than the deeper frequencies, which reach the listener with a time lag as glissandi sinking to almost bottomless depths.
