In previous newsletters, we have discussed animals such as dolphins and bats that are able to “see” with their hearing, a process known as echolocation, in which the animal can map their environment by sensing sound reflected back to them. There are animals, however, that utilize sound in a slightly different manner – not so much by “hearing” sound waves, but by feeling their vibrations. Read on to learn about audible arachnids.

“In space, no one can hear you scream.” The tagline from the sci-fi classic Alien is mostly true, but not entirely true. The transmission of sound requires a medium, which on Earth is usually air. Space is mostly an empty void, an icy vacuum that does not have the medium necessary for transmission of sound that humans can hear. However, space is not entirely empty, which allows for some sound transmission, if you know where to look. Read on to learn more about how sound travels in space.
Noise-Con 2022 was my first in-person conference since COVID, and it did not disappoint! Thanks to Institute of Noise Control Engineering – USA for putting on such a great conference in Lexington.

I was also the proud recipient of the Lang Award for Distinguished Noise Control Engineer! I want to share my acceptance speech for those of you who couldn’t attend.
The Metropolitan team has been out and about on construction sites throughout the city measuring vibration with our new platform SenSV. With the life science industry booming in Philadelphia, we have been using SenSV to measure ambient vibration in buildings to determine their suitability for various lab functions.

It’s May, and beach season is almost here! To humans, swimming in the ocean is a well-deserved vacation, but to marine animals, the ocean is home.

Read on to learn how animals are affected by ocean noise pollution.

Sports are an important part of American culture, at both professional and amateur levels of play, but they can present acoustic issues. Residents who live near courts and fields are often disturbed by the sounds of basketballs pounding on the pavement, whistles on the football field, or the crack of a base hit. A new sport, pickleball, is dominating the sports scene in many places across the country, with a two-year growth rate of almost 40% and up to 4.2 million players in 2021. Despite its popularity, it tends to generate many noise complaints from nearby residents. Read on to learn more about this banging sport and what can be done.
