OTTAWA, Ontario, May 14, 2024 – Walking out of a hair salon can have customers feeling brand new, but the noisy environment may have negative effects at the cost of a new “do.” At Image Creators salon in Maryland, owner Silvia Campana along with her employees and customers noticed they had to work hard to understand each other’s words while in the salon, but they couldn’t put their finger on exactly why. In addition to difficulties understanding speech, Campana experienced increased ear pain and tinnitus after long-term exposure to high sound pressure levels while working at the salon. These challenges inspired some creative solutions.

Campana consulted with Donna Ellis at Lines by Nature LLC to enhance the acoustical landscape at the high-end beauty salon. Ellis experimented with noise reduction methods to contribute to the calming, luxurious environment desired by the clientele and employees. She will present her work Tuesday, May 14, at 3:00 p.m. EDT as part of a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, running May 13-17 at the Shaw Centre located in downtown Ottawa, Ontario, Canada.

“Many noisy environments can be fixed in reasonably fast, cost-effective ways to provide social environments where our hearing is protected, where we can relax, and where we can have meaningful conversations with our friends, business colleagues, and family,” said Ellis.

Ellis collaborated with Campana to improve the salon’s acoustics and reduce the noise levels for the customers and staff. The main noise sources came from long reverberation times, high background noise from the HVAC system, hair dryers, and multiple people talking.

The pair found great success by installing acoustically absorptive materials throughout the salon. Reducing noise levels noticeably improved the ability to converse easily. In addition, receptionists were able to actually answer the phones at the counter and staff reported reduced ear pain.

“After the acoustics were retrofit the customers sensed a difference,” said Ellis. “When asked what changed, salon staff point up and it clicks. Customers often share their gratitude and surprise at the difference good acoustics make on their salon experience.”

The safety upgrades created for the salon are transferable to other noisy locations. With healthy noise levels being the focus, Ellis has data to show how noise reduction can be implemented within interior spaces.

“By balancing the listening environment, our findings can be applied to other salons, restaurants, stores, and conference centers to name a few,” said Ellis. “The solutions would support clear verbal communication in enclosed spaces and protect the occupational safety of the employees and customers.”

Ellis collected positive feedback from the occupants and emphasized the importance for communities and industries to support healthy human function as a whole.

Courtship Through Flute Song in Indigenous Southern Plains Culture #ASA186

Courtship Through Flute Song in Indigenous Southern Plains Culture #ASA186

For some tribes, performing an original flute song is the first step toward marriage.

OTTAWA, Ontario, May 14, 2024 – Every love story is unique, and in traditional Indigenous Southern Plains culture, it begins with an original ballad performed on the flute. In order to win a lover’s affection, and respect among the tribe, each pursuer must compose one good flute serenade.

Warrior with flute

“Warrior with flute” by Timothy Tate Nevaquaya.

Paula Conlon, a former music professor at the University of Oklahoma, has researched the history and cultural significance of the Indigenous flute since the 1980s. Conlon will present her work Tuesday, May 14, at 9:45 a.m. EDT as part of a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, running May 13-17 at the Shaw Centre located in downtown Ottawa, Ontario, Canada.

Conlon’s deep dive into this tradition includes a focus on four aspects that make a flute song “good” music: characteristics of the musical elements within the song, features that epitomize quintessential flutes, the qualities of the individual flute player, and how the flute players serve in their respective communities as mentors and role models. She also found that a love worth pursuing inspires its own music.

“Traditionally, a flute player would not use the same love song to court multiple partners, similar to a love letter or love poem,” said Conlon.

To study this romantic art form, Conlon looked to the works of flutists who helped maintain the tradition.

“The findings are based on an analysis of historical recordings of Indigenous flute love songs and the related literature, and the flute songs of Kiowa flutist Belo Cozad and Comanche flutist Doc Tate Nevaquaya,” said Conlon.

The decline of this courting tradition followed the end of the Reservation Era in 1887. Cozad and Nevaquaya are recognized for the survival of the Plains’ flute tradition, and nearly a century after the Reservation Era, in the late 20th century the tradition experienced a resurgence.

Nevaquaya was a leader in the Indigenous flute revival. He learned how to construct the flutes, personalized playing techniques, and put a spotlight on the old repertoire. He notably developed two new composition styles — one for modern courtship and the other to expand on the creativity of the individual flutist. His solo flute album, released in 1979, is regarded as a bridge between the traditional culture and the style of up-and-coming flute players.

“In 2024, it is another generation of Indigenous flute players, including Nevaquaya’s sons, Timothy, Edmond, and Calvert, who are making their mark,” said Conlon.

During her two-decade-long tenure in Oklahoma, Conlon developed relationships with many of the Indigenous flute players in the area. Now living in her hometown of Ottawa, she plans to continue this investigation by conducting comparable research on Indigenous flute players in Canada.

Catch and Release Can Give Sea Turtles the Bends #ASA186

Catch and Release Can Give Sea Turtles the Bends #ASA186

Veterinarians team up with fishers to evaluate the health of accidentally caught sea turtles.

OTTAWA, Ontario, May 13, 2024 – Six out of seven sea turtle species are endangered, and humans are primarily responsible. Commercial fishing activities are the largest human-caused disturbance to sea turtles due to accidental capture.

Fishers are typically unaware if a sea turtle is caught in their net until its completely pulled out of the water. However, releasing sea turtles without veterinary evaluations can be harmful. When accidentally caught, the turtles’ normal diving processes are interrupted, which can cause abnormal gas in their organs, gas emboli, to form. Veterinarians around the globe are working to understand the possible consequences of this pathology and determine the best treatment for turtles depending on when they surface. Here, they used ultrasound imaging to get a closer look at sea turtles’ bodies in realtime, focusing on the heart, liver, and kidney.

Katherine Eltz, a first-year doctoral student at the University of North Carolina at Chapel Hill, determined that there are ways to differentiate gas levels over time in sea turtles. Eltz, whose home laboratory focuses on ultrasound imaging for decompression sickness mitigation in humans, collaborated with veterinarians who measured gas emboli in turtles in real time on fishing boats. She will present her work Monday, May 13, at 4:00 p.m. EDT as part of a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, running May 13-17 at the Shaw Centre located in downtown Ottawa, Ontario, Canada.

“Veterinarians can examine whole-body MRI or X-ray scans and find specific bubbles in a variety of different organs,” said Eltz. “The benefit of ultrasound is that we can see bubbles flowing through vessels or stationary in tissues. The portability of ultrasound means that it can be brought onto fishing boats, which we took advantage of to collect half of the data used in this project.”

Her collaborators from the Oceanogràfic Foundation were the first to report decompression sickness in turtles. Eltz examined ultrasound data collected from sea turtles found off the coast of Brazil, Italy, and Spain, though this issue is found in sea turtles worldwide. The data collection from Eltz’s collaborators at Oceanogràfic comes from veterinarians who joined fishers off the coasts of these countries and imaged the turtles immediately to monitor their bubbles after surfacing.

Eltz’s results come from two experimental groups with different circumstances regarding time and gas severity. The brightness from the ultrasounds taken from the groups is a valuable quantitative metric to separate each ultrasound by grade. These findings can help veterinarians better treat sea turtles presenting with gas embolism. Ultrasound brightness could become a quantitative metric for veterinarians to determine which turtles need hyperbaric oxygen treatment and which can be released.

“The largest task still at hand is to work towards standardizing the acquisition of the ultrasound data collected for this project,” said Eltz. “Now, I can work with veterinarians to help adjust their methods, including improved image processing to standardize the data in post-processing.”

With a rich dataset from Oceanogràfic at her disposal, Eltz hopes to examine other possible factors that may be related to gas severity. These insights all help lead to better prediction of the outcomes for bycaught sea turtles.

Intense Ultrasound Extracts Genetic Info for Less Invasive Cancer Biopsies #ASA186

Intense Ultrasound Extracts Genetic Info for Less Invasive Cancer Biopsies #ASA186

Upcoming technology can extract cancer biomarkers from cells to enable affordable, noninvasive, and regular cancer screening.

OTTAWA, Ontario, May 13, 2024 – Ultrasound imaging offers a valuable and noninvasive way to find and monitor cancerous tumors. However, much of the most crucial information about a cancer, such as specific cell types and mutations, cannot be learned from imaging and requires invasive and damaging biopsies. One research group developed a way to employ ultrasound to extract this genetic information in a gentler way.

At the University of Alberta, a team led by Roger Zemp explored how intense ultrasound can release biological indicators of disease, or biomarkers, from cells. These biomarkers, like miRNA, mRNA, DNA, or other genetic mutations, can help identify different types of cancer and inform the subsequent therapy. Zemp will present this work Monday, May 13, at 8:30 a.m. EDT as part of a joint meeting of the Acoustical Society of America and the Canadian Acoustical Association, running May 13-17 at the Shaw Centre located in downtown Ottawa, Ontario, Canada.

“Ultrasound, at exposure levels higher than is used for imaging, can create tiny pores in cell membranes, which safely reseal,” Zemp said. “This process is known as sonoporation. The pores formed due to sonoporation were previously used to get drugs into cells and tissues. In our case, we care about releasing the contents of cells for diagnostics.”

The ultrasound releases biomarkers from the cells into the bloodstream, increasing their concentration to a level high enough for detection. Using this method, oncologists can detect cancer and monitor its progression or treatment without the need for painful biopsies. Instead, they can use blood samples, which are easier to procure and less expensive.

“Ultrasound can enhance the levels of these genetic and vesicle biomarkers in blood samples by over 100 times,” said Zemp. “We were able to detect panels of tumor-specific mutations, and now epigenetic mutations that were not otherwise detectable in blood samples.”

Not only was this approach successful at detecting biomarkers, but it also boasts a lower price compared to conventional testing. 

“We’ve also found that we can conduct ultrasound-aided blood testing to look for circulating tumor cells in blood samples with single-cell sensitivity for the price of a COVID test,” said Zemp. “This is significantly cheaper than the current methods, which cost about $10,000 per test.”

The team also demonstrated the potential for applying intense ultrasound to liquefy small volumes of tissue for biomarker detection. The liquified tissue can be retrieved from blood samples or through fine-needle syringes, a much more comfortable option compared to the damaging core-needle alternative.

More accessible techniques to identify cancer will not only allow for earlier detection and treatment but will also allow medical practitioners to be nimble in their approach. They can establish if certain therapies are working without the risks and expenses often associated with repeated biopsies.

“We hope that our ultrasound technologies will benefit patients by providing clinicians a new kind of molecular readout of cells and tissues with minimal discomfort,” said Zemp.
