In The Studio: 10 Things About Sound You May Not Know…

5) Noise harms and even kills. There is now wealth of evidence about the harmful effect of noise, and yet most people still consider noise a local matter, not the major global issue it has become.

According to a 1999 U.S. Census report, Americans named noise as the number one problem in neighborhoods. Of the households surveyed, 11.3 percent stated that street or traffic noise was bothersome, and 4.4 percent said it was so bad that they wanted to move. More Americans are bothered by noise than by crime, odors and other problems listed under “other bothersome conditions.”

The European Union says: “Around 20% of the Union’s population or close on 80 million people suffer from noise levels that scientists and health experts consider to be unacceptable, where most people become annoyed, where sleep is disturbed and where adverse health effects are to be feared. An additional 170 million citizens are living in so-called ‘grey areas’ where the noise levels are such to cause serious annoyance during the daytime.”

The World Health Organization says: “Traffic noise alone is harming the health of almost every third person in the WHO European Region. One in five Europeans is regularly exposed to sound levels at night that could significantly damage health.”

The WHO is also the source for the startling statistic about noise killing 200,000 people a year. Its findings (LARES report) estimate that 3 percent of deaths from ischemic heart disease result from long-term exposure to noise. With 7 million deaths a year globally, that means 210,000 people are dying of noise every year.

The cost of noise to society is astronomical. The EU again: “Present economic estimates of the annual damage in the EU due to environmental noise range from EUR 13 billion to 38 billion. Elements that contribute are a reduction of housing prices, medical costs, reduced possibilities of land use and cost of lost labour days.” (Future Noise Policy European Commission Green Paper 1996).

Then there is the effect of noise on social behavior. The U.S. report “Noise and its effects” (Administrative Conference of the United States, Alice Suter, 1991) says: “Even moderate noise levels can increase anxiety, decrease the incidence of helping behavior, and increase the risk of hostile behavior in experimental subjects. These effects may, to some extent, help explain the “dehumanization” of today’s urban environment.”

Perhaps Confucius and Socrates have a point.

6) Schizophonia is unhealthy. “Schizophonia” describes a state where what you hear and what you see are unrelated. The word was coined by the great Canadian audiologist Murray Schafer and was intended to communicate unhealthiness. Schafer explains: “I coined the term schizophonia intending it to be a nervous word. Related to schizophrenia, I wanted it to convey the same sense of aberration and drama.”

My assertion that continual schizophonia is unhealthy is a hypothesis that science could and should test, both at personal and also a social level. You have only to consider the bizarre jollity of train carriages now—full of lively conversation but none of it with anyone else in the carriage—to entertain the possibility that this is somehow unnatural.

Old-style silence at least had the virtue of being an honest lack of connection with those around us. Now we ignore our neighbors, merrily discussing intimate details of our lives as if the people around us simply don’t exist. Surely this is not a positive social phenomenon.
