This is a neat illustration of the problem of identifying music with its notation. Equating music with a sequence of note onsets, because this is how it looks on the page.

Is there no musical repetition here

Noise in the workplace
It seems noisy environments have quite a few negative implications:
"But the most problematic aspect of the open office may be physical rather than psychological: simple noise. In laboratory settings, noise has been repeatedly tied to reduced cognitive performance. The psychologist Nick Perham, who studies the effect of sound on how we think, has found that office commotion impairs workers’ ability to recall information, and even to do basic arithmetic. Listening to music to block out the office intrusion doesn’t help: even that, Perham found, impairs our mental acuity. Exposure to noise in an office may also take a toll on the health of employees. In a study by the Cornell University psychologists Gary Evans and Dana Johnson, clerical workers who were exposed to open-office noise for three hours had increased levels of epinephrine—a hormone that we often call adrenaline, associated with the so-called fight-or-flight response. What’s more, Evans and Johnson discovered that people in noisy environments made fewer ergonomic adjustments than they would in private, causing increased physical strain. The subjects subsequently attempted to solve fewer puzzles than they had after working in a quiet environment; in other words, they became less motivated and less creative."

Octave scrambled melody
As Diana Deutsch demonstrated, spreading the notes of a melody across different octaves effects our ability to recognise the melody.

Phenomenology of Sound
An introduction to Schaeffer's idea of the sound object, and a more detailed article explaining the idea of phenomenology in general and Schaeffer's development of it to sound.
Denis Smalley built on scheffer's idea to talk about the spectromorphology of sound. Here is an overview with list of additional sources.
Francis Dhomont's Acousmatic update gives his view as a composer influenced by Schaeffer and spectromorphology.
