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."

Automatic composition

In the words of the author:
"Autocousmatic generates electroacoustic music intended for acousmatic presentation. Based only on a seed directory of source sound files, a desired duration and number of output channels, the program creates multi-channel spectromorphological tape pieces. Audio analysis capabilities are used to discover 'useful' portions of sound files and assess processed files. The project investigates a deeper relation from machine listening to algorithmic composition tasks, and welcomes feedback."
Listen to some of the examples on the website and judge for yourself. And you can read Nick's CMJ article about the system.

Octave scrambled melody

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

Psychoacoustics in the recording studio

Producer Bruce Swedien considers understanding the nature of sound and hearing as an essential element in developing your studio skills:
Determining the abilities and limitations of human hearing is invaluable to us involved in the production of music recordings. Any resource that produces sound for the purpose of human listening should take into account what the listener’s ears are going to do with that sound, if we are going to take that resource to its utmost potential.
He also mentions the importance of listening - especially to live instruments - and the acoustic environment. Read the full article.

Why so loud?

Perhaps a truism of composition is that most (all?) effects can be overused. Including compression:

Hearing explained

A good resource covering the basics acoustics and psychoacoustics, as well as the ear, the auditory brain, and to hearing loss and current research.

The Science of Music

four programs from BBC radio4 with Robert Winston and guests.

Analysing electroacoustic music

New sounds, new techniques, new approaches to understanding(?):
  • Several Analysis articles from eContact.
  • The orema project is a growing resource with analysis examples, discussion of approaches, and other useful resources.
  • Rajmil Fischman's graphic score for Point-virgule.
  • graphic score of Schaeffer's Etude aux Objects
  • And a temporal analysis of another Schaeffer study. 

Soundscape Composition

Listen:


Organised Sound 7:1 is an issue dedicated to soundscape composition with papers by some prominent practitioners including Hilegard Westerkamp and Barry Truax. 
Issue 14:1, on the topic of sound art, also has good, relevant articles. While issue 16:3 (listening) is also highly relevant.
Andra McCartney on Soundscape composition and electroacoustic music. 

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.

Physclips

This wonderful multimedia presentations about the physics of sound and hearing. These were created for physics students so some parts have scary equations. Nevertheless these have excellent illustrations and explain the basics of sound from acoustic vibrations to perception very well. 

Music & Computers

This introductory text covers a range of topics from basic acoustics to synthesis with good examples and interactive tools.
