An intriguing tour d'horizon of the world of sound.
Cox (Acoustic Engineering/Salford Univ.; Acoustic Absorbers and Diffusers, 2009) explores how the psychological and physical worlds of sound come together.
Using the design of concert halls to illustrate “the fusion of the objectivity of physics with the subjectivity of perception,” the author explains how, in the final analysis, it is the audience that judges the quality of the acoustics. The reverberation of sound as it bounces around a room determines how we hear a sound—e.g., a live room such as a bathroom, where the sound is enhanced by the reflection of the sound, compared to the way that a plush hotel room dampens sound. However, a crucial element that necessarily eludes the acoustical engineer is the role of expectation in our response to sound. Neuroscientists are just beginning to unravel the mystery of how we perceive sound. Cox has devoted much of his career to the design of concert halls and theaters that enhance sound quality or quiet spaces that reduce unwanted noise. Fifteen years ago, he also became fascinated with common, everyday sounds in our environment. It all began when a BBC interviewer tapped his expertise as a sound engineer to explain the unusual acoustics found in a London sewer 20 feet below street level. The experience was a life-changer. “In the right place a 'defect' [such as]…the metallic, spiraling echo in the sewer, could be fascinating to listen to,” writes Cox. This was the start of a new phase of his career, during which he has presented 17 popular-science documentaries on different aspects of sound for BBC radio. He visited ancient Greek theaters and 16th-century cathedrals, participated in a Buddhist retreat and explored the acoustics of whispering galleries. His travels also took him to Neolithic sites and the sand dunes of the Mojave Desert.

Nicely textured account of what the Earth would look like if humans disappeared.
Disaster movies have depicted the State of Liberty poking out from the ground and empty cities overgrown with trees and vines, but what would really happen if, for one reason or another, every single one of us vanished from the planet? Building on a Discover magazine article, Weisman (Journalism/Univ. of Arizona; An Echo in My Blood, 1999, etc.) addresses the question. There are no shocks here—nature goes on. But it is unsettling to observe the processes. Drawing on interviews with architects, biologists, engineers, physicists, wildlife managers, archaeologists, extinction experts and many others willing to conjecture, Weisman shows how underground water would destroy city streets, lightning would set fires, moisture and animals would turn temperate-zone suburbs into forests in 500 years and 441 nuclear plants would overheat and burn or melt. “Watch, and maybe learn,” writes the author. Many of his lessons come from past developments, such as the sudden disappearance of the Maya 1,600 years ago and the evolution of animals and humans in Africa. Bridges will fall, subways near fault lines in New York and San Francisco will cave in, glaciers will wipe away much of the built world and scavengers will clean our human bones within a few months. Yet some things will persist after we’re gone: bronze sculptures, Mount Rushmore (about 7.2 millions years, given granite’s erosion rate of one inch every 10,000 years), particles of everything made of plastic, manmade underground malls in Montreal and Moscow. In Hawaii, lacking predators, cows and pigs will rule.
Weisman quietly unfolds his sobering cautionary tale, allowing us to conclude what we may about the balancing act that nature and humans need to maintain to survive.Pub Date: July 10, 2007

Science writer Ackerman (Ah-Choo!: The Uncommon Life of Your Common Cold, 2010, etc.) looks at the new science surrounding avian intelligence.
The takeaway: calling someone a birdbrain is a compliment. And in any event, as Ackerman observes early on, “intelligence is a slippery concept, even in our own species, tricky to define and tricky to measure.” Is a bird that uses a rock to break open a clamshell the mental equivalent of a tool-using primate? Perhaps that’s the wrong question, for birds are so unlike humans that “it’s difficult for us to fully appreciate their mental capabilities,” given that they’re really just small, feathered dinosaurs who inhabit a wholly different world from our once-arboreal and now terrestrial one. Crows and other corvids have gotten all the good publicity related to bird intelligence in recent years, but Ackerman, who does allow that some birds are brighter than others, points favorably to the much-despised pigeon as an animal that “can remember hundreds of different objects for long periods of time, discriminate between different painting styles, and figure out where it’s going, even when displaced from familiar territory by hundreds of miles.” Not bad for a critter best known for bespattering statues in public parks. Ackerman travels far afield to places such as Barbados and New Caledonia to study such matters as memory, communication, and decision-making, the last largely based on visual cues—though, as she notes, birds also draw ably on other senses, including smell, which in turn opens up insight onto “a weird evolutionary paradox that scientists have puzzled over for more than a decade”—a matter of the geometry of, yes, the bird brain.
Ackerman writes with a light but assured touch, her prose rich in fact but economical in delivering it. Fans of birds in all their diversity will want to read this one.Pub Date: April 12, 2016
