Sound

The Wave Organ is an acoustic sculpture that amplifies the sounds of the waves from the bay, creating low, gurgling notes that ebb and flow with the ocean.

Technicians have set out into US national parks to document the natural noises of the park, as well as ambient human noise, an audible invasion that may be stressful to wildlife.

A new brain study shows that we have a network of volume settings that can selectively silence and amplify the sounds we make and hear.

While the high-pitched melodies of small birds, like chirping sparrows, rise above man-made noise, larger birds are forced away from noisy areas as their lower-pitched songs are drowned out in the cacophony.

Google's augmented reality spectacles create sound by sending vibrations directly through the wearer's skull. Called "bone conduction audio," the tech allows you to hear the noise in the environment too.

Their buzzing can reach 90 decibels, as loud as some power motors. They have been seen in clusters of up to 1.5 million per acre. As if from some horror movie, cicada nymphs have been described as “boiling out of the ground."

Elephants can relate information regarding their location, sexual receptivity, and the presence of water to other herds via low frequency sound waves traveling through the ground.

An experimental aircraft that designers hoped would hit 3,600 mph in a test flight over the Pacific on Tuesday "suffered a control failure" and failed in its attempt to go hypersonic.

Some biologists are studying how separate species orchestrate different sounds together, and how the resulting soundscape can be used to gauge the health of ecosystems.

With a little luck and a crack team behind him, Felix Baumgartner plans to skydive into the record books. Climbing to roughly 23 miles (37 kilometers), he'd be the first human to achieve supersonic speed with just his body.

Bosch has released a brand new ultrasonic sensor, blind spot assistant which can warn you if another vehicle is alongside or diagonally behind.
