Pickleball Courts in a Legal Pickle #ASA186

Pickleball Courts in a Legal Pickle #ASA186

When advising on the noise associated with pickleball, loudness is just one of many concerns, and solutions require infrastructure or limitations on play.

OTTAWA, Ontario, May 17, 2024 – Pickleball Legal Consultant is a job title that likely did not exist a decade ago, but as pickleball courts infiltrate neighborhoods to satiate an appetite for a sport whose namesake is a snack, communities take issue with the resulting influx of noise. Now homeowners’ associations and city councils face litigation by those whose lives are disrupted by pickleball’s din.

Charles Leahy, an attorney, retired mechanical engineer, and former HOA board member became interested in this issue after his HOA dismissed the recommendations of noise consultants and failed to install noise absorbing barriers. Litigation over noise nuisance ensued and threatens closure of the courts.

Leahy sought to understand how acoustic engineers assess the noise, how they fashion their recommendations, and what best practices engineers can employ to persuade the community that the noise is real and needs to be mitigated. He will present his work Friday, May 17, at 8:35 a.m. EDT in a session dedicated to pickleball 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.

Pickleball

Experts recommend HOAs and communities consider the “popping” noise associated with pickleball when deciding to build courts near homes. Image credit: AIP

“Compared to tennis, pickleball is a much smaller court, easier to learn, and especially accessible to seniors,” said Leahy. “Each tennis court can become up to four pickleball courts. Tennis involves a soft and compressible ball and a racket with strings. Pickleball is a hard plastic ball and a hard paddle. Tennis produces a ‘thunk’ sound versus pickleball ’pop,’ which is louder, sharper, more piercing, and more frequent. Thus, more annoying.”

Communities looking to invest in – and those facing lawsuits because of – the courts often seek out engineering consultants to advise them. Leahy examined over 70 pickleball consultant noise reports and compared their recommendations with the American National Standard Institute. He found many reports considered only the decibels associated with the noise, but other factors are important too.

“It’s not just the loudness, it’s the impulsive sharpness and randomness of the ‘pops,’” said Leahy. “It’s the persistence and repetition of the random noises over many hours a day, usually seven days a week.”

His best recommendation is to build courts far from homes, at least 600-800 feet away to allow the sound to naturally dissipate. Less desirable (or more difficult or costly) solutions include enclosing the courts within a building or wall barriers or using less noisy paddles and balls.

“Pickleball has a highly impulsive noise, with each court generating about 900 pop noises per hour,” said Leahy. “It’s incompatible with residential living. Cities can also locate pickleball in industrial and commercial neighborhoods rather than close to homes.

“The benefits of pickleball to the players are undeniable, and the demand for more pickleball courts is real and genuine. However, there needs to be more research, more planning and prevention, and more effort to avoid ending up in front of the judge and jury.”

AI-Powered Headphones Filter Only Unwanted Noise #ASA186

AI-Powered Headphones Filter Only Unwanted Noise #ASA186

Neural network categorizes ambient sounds, giving users the power to choose what to hear.

OTTAWA, Ontario, May 16, 2024 – Noise-canceling headphones are a godsend for living and working in loud environments. They automatically identify background sounds and cancel them out for much-needed peace and quiet. However, typical noise-canceling fails to distinguish between unwanted background sounds and crucial information, leaving headphone users unaware of their surroundings.

Shyam Gollakota, from the University of Washington, is an expert in using AI tools for real-time audio processing. His team created a system for targeted speech hearing in noisy environments and developed AI-based headphones that selectively filter out specific sounds while preserving others. He will present his work Thursday, May 16, at 1:20 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.

“Imagine you are in a park, admiring the sounds of chirping birds, but then you have the loud chatter of a nearby group of people who just can’t stop talking,” said Gollakota. “Now imagine if your headphones could grant you the ability to focus on the sounds of the birds while the rest of the noise just goes away. That is exactly what we set out to achieve with our system.”

Headphones

Researchers augmented noise-canceling headphones with a smartphone-based neural network to identify ambient sounds and preserve them while filtering out everything else. Image credit: Shyam Gollakota

Gollakota and his team combined noise-canceling technology with a smartphone-based neural network trained to identify 20 different environmental sound categories. These include alarm clocks, crying babies, sirens, car horns, and birdsong. When a user selects one or more of these categories, the software identifies and plays those sounds through the headphones in real time while filtering out everything else.

Making this system work seamlessly was not an easy task, however.

“To achieve what we want, we first needed a high-level intelligence to identify all the different sounds in an environment,” said Gollakota. “Then, we needed to separate the target sounds from all the interfering noises. If this is not hard enough, whatever sounds we extracted needed to sync with the user’s visual senses, since they cannot be hearing someone two seconds too late. This means the neural network algorithms must process sounds in real time in under a hundredth of a second, which is what we achieved.”

The team employed this AI-powered approach to focus on human speech. Relying on similar content-aware techniques, their algorithm can identify a speaker and isolate their voice from ambient noise in real time for clearer conversations.

Gollakota is excited to be at the forefront of the next generation of audio devices.

“We have a very unique opportunity to create the future of intelligent hearables that can enhance human hearing capability and augment intelligence to make lives better,” said Gollakota.

Noise Survey Highlights Need for New Direction at Canadian Airports #ASA186

Noise Survey Highlights Need for New Direction at Canadian Airports #ASA186

Annoyance data gathered during pandemic reveals flaws in existing methods to assess and mitigate noise impacts.

OTTAWA, Ontario, May 16, 2024 – The COVID-19 pandemic changed life in many ways, including stopping nearly all commercial flights. At the Toronto Pearson International Airport, airplane traffic dropped by 80% in the first few months of lockdown. For a nearby group of researchers, this presented a unique opportunity.

Julia Jovanovic will present the results of a survey conducted on aircraft noise and annoyance during the pandemic era Thursday, May 16, at 11:10 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.

“For many years, researchers like me have looked to assess the impacts of aircraft noise on communities surrounding airports, particularly in terms of annoyance,” said Jovanovic. “The travel restrictions due to COVID and the resulting sustained reductions in noise gave us an unprecedented opportunity to test the correlation between noise and annoyance.”

In early 2020, the NVH-SQ Research Group out of the University of Windsor surveyed residents living around the airport to gauge how their annoyance levels changed with the reduction in noise. A follow-up survey in 2021 provided even more data for the researchers, and according to Jovanovic, they highlight flaws in the tools authorities use to assess and manage the impacts of aircraft noise on communities.

“The industry has, for too long, erroneously relied on noise complaints as a proxy measure for annoyance,” said Jovanovic. “These surveys show that complaints and annoyance are different phenomena, triggered by different mechanisms. Only annoyance has a proven correlation to overall noise levels.”

According to their data, while noise complaints dropped overall during the pandemic, many of the people sending those complaints continued to do so, and some areas even saw an increase in complaints. This demonstrates the need for collecting survey data on annoyance specifically, something Canadian authorities overseeing air transport have been reluctant to do.

“Even though the annoyance metric draws much criticism due to its subjective nature, it is still indicative of the overall effect of aircraft noise on individuals and the resulting possible long-term health impacts,” said Jovanovic. “These types of surveys are conducted in most developed nations on a regular basis. To the best of our knowledge, we are unaware of any similar efforts in any other Canadian airport.”

Jovanovic and her colleagues hope these results will spur regulatory agencies to collect better data and use it to develop more updated standards and guidelines for protecting the public from aircraft noise and protecting the future of airport operations from continuous residential encroachment.

“The survey should be repeated around all of our nation’s airports to get an accurate representation of the effects of aircraft noise on Canadian communities and update Transport Canada’s severely outdated guidelines for the management of aircraft noise,” said Jovanovic.
