Signal

Move across the poster. The signal keeps its shape. The noise does not.

A lecture series for anyone who has strained to hear one voice in a crowded room.

Every Tuesday, one way of hearing.

Scientists, engineers and artists talk about what it takes to pull meaning out of a racket. Each talk runs for an hour, followed by questions and a glass of something.

  1. The first sound you ever heardMira Oberholzer, acoustician
  2. Cocktail parties and the selective earTomas Reyes, cognitive scientist
  3. Listening for thirteen billion yearsInes Kalb, radio astronomer
  4. What the city sounds like at 4 a.m.Jun Takeda, field recordist
  5. Compression, or how to lose data wellLeila Haddad, audio engineer
  6. Silence is not emptyAnouk Sutter, composer

Talks start at 19:30, doors at 19:00. Each evening has 120 seats, and reserving one takes a minute.
