A paper published in Nature Scientific Reports describes researchers using a Dodotronic Ultramic384, an Oppo smartwatch, and a Xiaomi Mi A1 smartphone to record audio of the sound of a #1 hitting the water surface in a toilet bowl. The audio was analyzed using machine-learning regression algorithms to determined urine flow parameters such as voided volume and flow rate, and was compared with a commercial grade Minze uroflowmeter.
The tests involved peeing into a Minze uroflowmeter basin, and at the same time three different microphones recorded the sound. The Minze uroflowmeter was prefilled with 400 ml of water at the bottom of the container, to ensure that the sound generated by the twinkle was against the water, simulating the conditions of a real toilet bowl. All participants were given instructions asking them to aim at the toilet water.
The results showed there was very good correlation between using the smart devices and the ‘gold standard’ device.
The 6th Edition of Engineering Noise Control has been released in paperback, hard cover, and Kindle.
Companion software with the book is also available for download from the authors’ web site.

A story on the New York Post describes a fake kidnapping and ransom demand using deep-fake audio of a 15-year-old girl from Scottsdale Arizona, USA. The kidnappers called the mom and claimed they had kidnapped her daughter, who was on a school ki-trip at the time, and demanded $US 1 million, but then lowered the ransom to $50k. The fake audio of the daughter sounded exactly like her daughter and were convinced it was their daughter. The parents called the police, and they confirmed the daughter was safe on the excursion.
The Acoustics 2021 conference, originally planned for November 2021 in Woollongong, New South Wales, Australia has been postponed until 21-23 February 2022.
New South Wales currently (2021-08-28) has an outbreak of COVID-19, currently 13,880 active cases, so holding a face-to-face conference presents a risk to potential attendees.

A company called Syng, have released a new loudspeaker called the Cell Alpha Triphonic Speaker. Company co-founder, Christopher Stringer worked for Apple during 21 years and left in 2017 to create Syng. He was involved directly in developments for the iPhone and iPad, Apple Watch, and the HomePod. Stringer is referenced on more than 1,400 US patents. The first Triphonic sound system was actually patented in 1984 by Emil L. Torick (inventor) on behalf of CBS Broadcasting.
The global situation with COVID continues and has caused many conferences to change to a virtual conference, and dates have been rescheduled. The Events Calendar on Noiseboard has been updated with conference dates.
