We are given early signs of O'Donoughue's intentions when he follows in the footsteps of Ben Burt who was one of the original pioneers of sound. After he recorded the sound of him breathing in an old scuba regulator to achieve the sound of Darth Vader it is clear that O'Donoughue obviously had similar plans when recording himself blowing up a balloon to simulate the sound of snoring/sleeping.
Ever since the early creativity shown by Jack foley the possibility within sound has only been on the uprise, and with access to a foley studio O'Donoughue hasn't held back. Even the slightest sounds within the piece such as when the boy tries to grab his phone to switch off his alarm sound would go unnoticed unless pointed out. The clear and crisp sound that is produced from a foley studio is what keeps sound in film unnoticed. While people are quick to praise a film's cinematography, music, special effects and editing, the art of sound effects creation, or Foley, usually goes unnoticed.
However, unlike those other aspects of filmmaking, Foley artists don't want their work to stand out . And whilst the concept of O'Donoughue's piece may seem simplistic it is the magic of foley that keeps you from knowing the true complexity of it.
The ending of the piece should be specifically highlighted as in the clip all three alarms go off at the same time, during this scene the camera focuses on each alarm one at a time and O'Donoughue has managed to smoothly blend each of the sounds together by fading in and out of one another whilst keeping them all playing at different volumes, giving you the impression that you are as close to the alarm as the camera is. The camera then pans out and all of the sounds increase in volume heavily to express what the boy in the clip is hearing and the laziness of the boy is almost contagious as the three alarms at top volume give the viewers the same feeling of annoyance. The clip is then ended with the boy drawing his covers over his head which brings an end to all the sound completely by cutting to black.
Whilst O'Donoughue has a unique range of acoustic sounds and transitions he has achieved that of which to give the audience the illusion of that they might not be hearing what they think.
