World Listening Day 2022: Listening Across Boundaries

Today we announced that the theme for World Listening Day 2022 will be “Listening Across Boundaries.” I’m super excited to have been chosen as the theme creator for this year and that my choice of theme seems to resonate with so many and in such interesting directions.

World Listening Day is celebrated every year on July 18th.

Mark Ballora

Mark Ballora, a dear friend and collaborator, was a pioneer in acoustics and “sonification” of data. A memorial service is being held this weekend at Penn State, where he was a professor of music technology.

Naturally I collected my thoughts about carrying forward his energy and vision in musical form. This short composition (<2.5 min) incorporates a musical cipher of his name, coral reef sounds, and audio recordings he made of me pitched at his vocal frequency, as a symbol of my dedication to seeing his voice, missions, and work are carried forward.

National Academies Keck Futures Initiative Announces Winners of the NAKFI Challenge

WASHINGTON — The National Academies Keck Futures Initiative (NAKFI) is pleased to announce the recipients of three $500,000 NAKFI Challenge awards. A 15-year, $40 million dollar program funded by the W.M. Keck Foundation, NAKFI was initiated in 2003 to break down barriers between fields and to promote interdisciplinary research. The NAKFI Challenge awards support activities that will carry forward NAKFI’s work beyond its 15 years as an activity of the National Academies of Sciences, Engineering, and Medicine.

Open only to NAKFI alumni who participated in the program’s annual interdisciplinary conferences, the call for proposals generated 78 applications. Applications underwent a round of peer-to-peer community judging by fellow applicants. The 30 highest scoring proposals were then judged by an expert panel consisting of members of NAKFI conference organizing committees. The three winners were chosen by the presidents of the National Academy of Sciences, the National Academy of Engineering, and the National Academy of Medicine.

The recipients, with NAKFI alumni in bold, and their project titles are:

Jody Deming, University of Washington
* Fiscal agent for grant, Djerassi Residents Artists Program
Daniel Kohn, Kohnworkshop
Heather R. Spence, Marine & Bioacoustics Programs, Michelle’s Earth Foundation (GRACIASS)
Jonathan Berger, Stanford University
Timothy J. Broderick, Institute for Human and Machine Cognition
Margot H. Knight, Djerassi Residents Artists Program
Timothy W. Weaver, University of Denver
Ocean Memory: A New Cross-Disciplinary Approach to Global-Scale Challenges
Memory involves the recall of events, pruned and processed from countless recordings by neural networks and thereby shaping future behavior. The ocean and its inhabitants hold memories of events throughout the evolution of the planet, awaiting our cognition. This proposal established a thriving community exploring and expressing Ocean Memory, a new line of highly evocative scientific inquiry , aiming for a sea change in our ability to address challenges of the Anthropocene. The approach builds upon NAKFI best practices, spanning disciplines required to address agents of memory and adding novel elements of distributed interactive spaces and grants for cross-disciplinary mentoring.

‘Reef Recall’ cello+soundscape performance July 8 in DC

_20151009_113752As part of my ongoing work on Ocean Memory, on July 8 2018 at noon I will present a new composition for live solo cello with recorded coral reef soundscape composition entitled ‘Reef Recall.’ The piece explores past crustacean and fish conversations in the context of natural and human-imposed cycles. The performance is sponsored by the Smithsonian Hirshhorn Museum and DC Listening Lounge ‘Sound Scene XI: Mapping Memory’.

Sound Walk for Dolphin Day

Celebrate Dolphin Day by going on a sound walk!


Sound is central to dolphin lives. They use sound not only for communication, but also to “see” using echolocation!

You can learn more about sound in the environment and have a good time by going on a Sound Walk:

Choose a location. Any location. Alone or with a group.
Close your eyes and listen to any sounds you hear.
Now open your eyes and move to another nearby location. Do the same thing.
What sounds are the same? What sounds are different?
Try to describe the sounds. What is the source of the sound? What does the sound “sound” like?
What sounds are produced by living creatures? By machines?
Which sounds seem pleasant? Unpleasant?

Keep going as long as you can! You can also try multiple locations, indoors or outdoors.

You’ll be amazed at the things you discover when you actively focus on the wealth of sonic information that is all around us!

Spread the word and raise awareness of noise pollution and the importance of sound to dolphins!

Sound and the Sea panel at National Academy of Sciences

In March I had the honor and privilege to curate and moderate a panel on Sound and the Sea at the National Academy of Sciences, as part of the DASER series. Bringing together science, music, policy and more we explored the ocean as a world of sound and how we can better respect and listen to it.

Videos of the presentations are now up on you tube -check them out!
