"Ever wonder why your voice sounds so much better when you sing in the shower? It has to do with an acoustic "blur" called reverberation. From classical to pop music, reverberation "makes music sound nicer," acoustic engineer Trevor Cox tells Fresh Air's Terry Gross. It helps blend the sound, "but you don't want too much," he warns."

It's one thing to record audio of a drummer and then digitally synthesize the reverberation to mimic various environments, but it's another thing entirely to film a drummer actually playing in all of those environments and then stitch it together into a single track. That's exactly what Audio Zero and Wikidrummers did with drummer Julien Audigier who played the same drum pattern in a variety of indoor and outdoor locations to show the effects of natural reverb, sometimes even blending multiple tracks into a single shot. Amazing. "

"Reverberating through the Pulitzer's iconic building, Adkins's works carry the potential of sound, and remain alluring even in silence. "

OPEN ACCESS FORTHCOMING AUTHORS ABOUT CONTACT A Slightly Curving Place asks what it means to listen to the past and its absence which remains. It responds to the practice of acoustic archaeologist Umashankar Manthravadi, whose life and work are a history of sound and technology through the second half of the twentieth century. As a self-taught acoustic archaeologist, he has been building ambisonic microphones since the 1990s to measure the acoustic properties of premodern performance spaces. Comprising a range of perspectives in which his propositions reverberate, the publication attends to what he does, and to the political and performative potential of the past that he opens up.

"This 9-channel sound, light & smoke installation was created in collaboration with the independent sonic arts collective Call & Response, Sep 2015 London Subterraneous takes the work of seventeenth century alchemist and scientist Athanasius Kircher as inspiration. Kircher was a polymath and inventor, who researched fields as diverse as medicine and Egyptology, and designed and constructed wondrous sound and vision automatons. These included a collection of so called speaking statues whose spiral mouths would lead out into the streets of Rome like giant trumpets. In this way the speaking trumpets or 'hearing lens' would reveal the cacophony of Rome to the listener. London Subterraneous aims to link Kircher's 'speaking trumpets' with his fascination of geology and underground reverberations and find a way to explore London's mundus subterraneous For this project, special microphones have been used to access sounds from a series of "stink pipes" that connect the city's familiar terrestrial environment to a lesser-known complex network of sewers and rivers below. The towering, hollow pipes, now rusting fixtures dotted across London erected as safety valves to vent excess toxic gases along a newly built Victorian sewer network in the 1860's allow us to connect through our past and eavesdrop on the capital's underground world. The resultant exhibition is a portrait of some of the sounds created below ground and through the pipes themselves "Although these stink pipes are nowadays "useless" this work aims to reveal them as poles of sound, or as singing flutes. In a way these are tones from the past." Jacob Kirkegaard"

«Using simple and functional components, Zimoun builds architecturally-minded platforms of sound. Exploring mechanical rhythm and flow in prepared systems, his installations incorporate commonplace industrial objects. In an obsessive display of curiously collected material, these works articulate a tension between the orderly patterns of Modernism and the chaotic forces of life. Carrying an emotional depth, the acoustic hum of natural phenomena blends effortlessly with electric reverberation in Zimoun's minimalist constructions.» bitforms nyc

"The Cathedral of Noyon houses the most unusual-and largely unknown-installation of acoustic vases in Western Europe, the caveau phonocamptique, a chamber installed beneath the pavement of the crossing. Acoustic vases are simple earthenware pots placed in the walls and vaults of postclassical churches, their installation inspired by Marcus Vitruvius Pollio's De architectura libri decem. "

""Toward the Circle" is silent short film created during a research residency at the Experimental Media and Performing Arts Center (EMPAC) in Troy, NY. It presents a sequence of enclosures, each with a simulated burst of sound energy, that hints at an important relationship between sound and architecture.

"This is me walking through different rooms of the same building. I compare the acoustic response of each room by means of a pair of metal plates that I attached to the sole of my shoes."

This is a pretty good layman's description of the relationship between sound wavelengths (their pitch in Hz) and the size of the room they are played back in.

"The world of acoustics is not just confined to finely tuned auditoriums and recording studios. The most intriguing sonic experiences can be had in some of the world's unique buildings and structures. "

"Sounds carry intelligence. If you are too narrow in your awareness of sounds, you are likely to be disconnected from your environment. Ears do not listen to sounds; the brain does. Listening is a lifetime practice that depends on accumulated experiences with sound; it can be focused to detail or open to the entire field of sound. Octogenarian composer and sound art pioneer Pauline Oliveros describes the sound experiment that led her to found an institute related to Deep Listening, and develop it as a theory relevant to music, psychology, and our collective quality of life. Pauline is a composer and accordionist who significantly contributed to the development of electronic music. The culmination of her life-long fascination with music and sound is what inspired the practice of Deep Listening, the art of listening and responding to environmental conditions. As a Professor of Practice in the Arts Department at Rensselaer Polytechnic Institute, she produced highly regarded work as a composer and improviser. Pauline's 1989 recording, Deep Listening, is considered a classic in her field."

Chapter One: An Acoustics Primer Sound waves reflect off of harder surfaces the same way billiard balls bounce off the bumpers of a pool table-the angle of incidence equals the angle of reflection. A sound wave hitting a flat wall at 45° will reflect off it at 45°. These bounces will continue until the sound has been completely attenuated by the inefficient reflection (called damping) of the surfaces along with the normal falloff of the sound waves themselves."
