"A new study shows microphones suspended from helium balloons in the stratosphere can detect low-frequency sounds from ocean waves. The new method shows promise for detecting acoustic signals from natural disasters and nuclear explosions that cannot always be reliably detected by sensors on the ground, according to the study's authors."

Vibrations conducted through a person's bones produce the uncanny sensation of low sounds emanating from within the body. The New York-based artist Sergei Tcherepnin draws on this effect in Stereo Classroom Chairs (2015), mounting a transducer to the underside of each wooden seat on which visitors are invited to sit. When not attached, a transducer plays sounds quietly, at a level that is almost inaudible. When its surface touches another object, however, the material characteristics of that object filter the sounds in various ways. Here, Tcherepnin's audio composition travels through the body of each sitter with a physical intensity. The chair amplifies the composition, while the sitter acts as the filter, amplifying low-frequency sounds and muffling higher frequencies.

"Stars oscillate on a - very - low frequency, which has to be pitched up many times to be heard by us humans. Scientists use the Kepler Space Telescope to measure these oscillations, and by the frequency they can tell the size of the stars. They combine this with the study of planets in the zone around the star where the temperature allows water to be liquid. Will this eventually lead us to the discovery of extraterrestrial life? "

"In this article we look at how bass is felt rather than heard, and, after reviewing some of the research that has been done in this area, we investigate the points at which low frequencies go beyond sound and become a tactile sensation in an experiment of our own."

"Fure, a composer and sonic artist whose works often involve the live modification of prerecorded electroacoustic tracks, unleashed an hour-long storm of sound, incorporating extremely low bass frequencies that began below the range of human hearing and slid upward to a barely perceptible 30 Hz. For a few minutes, I stood in front of a tower of speakers, having taken the precaution of inserting earplugs, and had a purely visceral encounter with sound-one that gave me the unsettling and liberating sensation of being no longer material in my own body."

"The 80-acre green space is the Buitenschot Land Art Park. Its trenches and ridges hold bike paths and sports fields, but these recreational features are a bonus. Its main purpose is to deflect ground noise, the low-frequency drone that planes make when they take off and land."

"ELECTROCHROMA is a 58ʼ30" audiovisual work that emerged from the manipulation of light to generate imagery as well as using a combination of extended techniques applied to sonic-material sources, including translation of image to sound to create the 5.1 surround audio composition. The work utilizes various analog and digital procedures and a variety of software processes to manipulate the moving image and sound. The workʼs imagery ranges from dark to light monochromatic spheres, shifting dynamics and intensity, including flickering and pulsating patterns, retinal impact, and sensory overloads. The sound composition focuses on timbre, low ends, modulated frequencies, textures, static noises, and electronic sounds moving through space. Other sonic layers were created through the use of electromagnetism, custom electronic sounds, and voices scored for the work and performed in a recording studio by artist Marylea Martha Quintana."

"A new art expedition aims to record qualitative and quantitative data with a custom-built set of tools on a year of trips through some of the most fascinating places in America. " " Up first, we see their very low-frequency antenna, which they built from a kit developed by Stephen McGreevy with Christopher Woebken's design. The antenna captures the sounds of spaceweather, the nice name for the environmental conditions created by the sun casting particles at the Earth. As Geoff told me, "You can walk right up to the tripod, put on green headphones, and zone out to the otherworldly whistles and pops of the Earth's magnetosphere."

"You might have seen the news last month that two students from George Mason University developed a way to put out fires using sound. "It happens so quickly you almost don't believe it," the Washington Post reported at the time. "Seth Robertson and Viet Tran ignite a fire, snap on their low-rumbling bass frequency generator and extinguish the flames in seconds." "

S.T.R.H. Smoleński's installation fills the main exhibition hall of the Łaźnia Centre for Contemporary Art in Gdańsk entirely, denying viewers a safe distance and pulling them towards its interior. The visual elements consist of massive, static, 3-dimensional objects which generate low-frequency sound at specific intervals. The sound unfolds from a nearly inaudible acoustic pressure into powerful rumblings that shake everything in their path - including the walls of the space and the body of the viewer - and eventually dissipate into complete silence. This way, contact with the work of art becomes a total sensory experience that involves not only the viewer's vision and hearing but their whole body; it is an entirely physical sensation. Though not devoid of a visual presence, the piece makes its impact mainly with sound, which, generated in specific ways, creates the impression of an all-encompassing experience - a synthesis of the senses that combines cues perceived by spatial receptors (eyes and ears) and contact receptors (skin and muscle).

"At the center of the conference is a specially built raised floor that is activated by low-frequency vibration. By sitting, standing, and lying on the floor, hearing and deaf participants are able to experience sound through their bodies. During the conference, presenters use the floor as a vehicle for tactile communication."

"I gave a talk on my Masters Thesis Project in Architecture focusing on Altering Soundscapes in Exterior Environments using Helmholtz Resonators in Ceramic Bricks to absorb Low Frequency Traffic Noise."

This CD consists of geothermal recordings of vibrations in the ground around the area of Krisuvik, Geysir and Myvatn in Iceland. The recordings have been carried out using accelerometers inserted into the earth at various places around the geysers, mapping the sonic aspects of volcanic activity at the surface of the earth."
