ANNA RAMOS AND ROC JIMENEZ DE CISNEROS: FOUR CONSECUTIVE STEPS TOWARDS MIDDLE WORLD – PART 3 – FOR RADIO BOREDCAST

These ultrasonic recordings of Vespertilionidae bat echolocation calls were made in the summer of 2011 using a CDB101R3 heterodyne stereo bat detector and a Tascam DR-100 digital recorder. The recordings were made in Parc de la Ciutadella in Barcelona.

Many overlapping pulse trains indicate groups of low flying bats feeding on insects – often just a few centimetres above head height. Those sections in which pulses do not overlap feature isolated bats flying in circles of about 15 meters in diameter. The frequency range of calls lies approximately between 35-60 KHz, and in some sections it is possible to hear other sound sources such as crickets, footsteps, people talking, or the fountain where the bats catch their prey.

The four shows in this series are based on the same recording, slowed down in each successive show in an attempt to reflect on the relativity of the concept of slowness and to try and transcend the anthropomorphic take on this subject. Middle World, a term coined by Richard Dawkins, is used to describe the realm between the microscopic world of quarks and atoms and the larger view of the universe at the galactic and universal level. This term is used as an explanation of oddity at both extreme levels of existence.
