Killer Whale Echolocation Clicks

Trains, Fog, Echolocation

A field recording of Sperm Whales, echolocating,  in Southern Bay, north of Princeton, Newfoundland. The clicks' frequency can suggest a whale's size and the rate, the distance between the whale and an object (e.g., prey). 

A Sperm whale head contains the spermaceti organ, a cavity filled with almost 2,000 L of wax-like liquid, and the junk compartment, comprising a series of wafer-like bodies believed to act as acoustic lenses. 

Echolocation signals are produced with consistent inter-click intervals (of approximately 0.4 s) while coda clicks are arranged in stereotypical sequences called “codas” lasting less than 2 s. Codas are characterized by the different number of constituent clicks and the intervals between them (called inter-click intervals or ICIs). Codas are typically produced in multi-party exchanges that can last from about 10 s to over half an hour. Each click, in turn, presents itself as a sequence of equally spaced pulses, with inter-pulse interval (IPI) of an order of 3–4 ms in an adult female, which is the result of the sound reflecting within the spermaceti organ.

Sperm Whale Echolocations

echolocation

through the woods

This piece was inspired during a trip to Pembrokeshire in 2019 where I witnessed the nightly antics of a colony of bats. It's quite a spectacle to observe them during their hunt for food, a little like an airborne ballet as they swoop at their prey.

The piece took about a year to compose. The echolocation sounds were recorded using a bat detector that lowered the frequency of the ultrasonic sounds so they were audible to the human ear.

Prior to this, I was unaware of just how prevalent bats are in the UK. Most of the sounds used were recorded in my parent's back garden.

This track contains a recording of the echolocation sounds of some of the 13 native to Vitosha mountain species of bats. The original frequency of the sounds on this recording was at about 40 kHz. They were pitched down in order to make them audible for us. I tried to do the pitching down in a way that preserves the original character of the sound the best, but it's not possible to preserve it entirely, the original sounds are even pluckier and more well defined. 
Observing different recordings I noticed that the bats are using sounds in a very broad frequency spectrum - some were as low as 18 kHz, others were as high as 60 kHz. Very fascinating creatures! Enjoy the clicks!

Did you know that you are an acoustic dampening device? That frequencies come to rest in your puffy jacket, frizzy hair, soft skin?
