Song sparrows adjust their songs to fit in with urban noise

While at Reed College in Oregon, Yezerinac and student William E. Wood examined the effects of urban noise on the song sparrow songs of Portland. They recorded 28 birds in areas with various levels of background noise, carefully measuring frequency (pitch) and amplitude (volume; the amount of energy invested in making a sound).

Birds in the noisiest spots were more likely to cede some of their lower frequencies to background noise, while their songs' higher-frequency notes remained constant.

One Square Inch of Silence

One Square Inch of Silence is the quietest place in the United States.

One Square Inch of Silence was designated on Earth Day 2005 (April 22, 2005) to protect and manage the natural soundscape in Olympic Park’s backcountry wilderness. The logic is simple; if a loud noise, such as the passing of an aircraft, can impact many square miles, then a natural place, if maintained in a 100% noise-free condition, will also impact many square miles around it. It is predicted that protecting a single square inch of land from noise pollution will benefit large areas of the park.

Eerie Sounds of Saturn's Radio Emissions

Saturn is a source of intense radio emissions, which have been monitored by the Cassini spacecraft. The radio waves are closely related to the auroras near the poles of the planet. These auroras are similar to Earth's northern and southern lights. This is an audio file of radio emissions from Saturn.

Soundwalkers

Soundwalkers documentary by Raquel Castro

There are some fundamental principles regarding the construction of an acoustically healthy society, one where we can exist within the sounds of life. Respect towards voice and words, sonic awareness, the awakening of the sense of hearing. To preserve the sounds that tend to fade out, while remaining open to the sounds that spring out of each technological stride. To build an aural idiom that interprets its own symbolism. To accept the silence, enforcing it in the due moments. And, above all else, to listen.
