The greater wax moth has the best hearing of any animal, using tympanal organs to detect sounds up to 300kHz, which helps it evade predators like bats. Despite lacking traditional ears, these simple membranes enable the moth to have an extraordinary sense of hearing, likely evolved as a defense mechanism.
Researchers have discovered that slingshot spiders, found along Ohio's riverbanks, use a unique hunting technique similar to Roman gladiators by launching their webs at prey using sound detection. These spiders can detect the sound of approaching insects, like mosquitoes, and release their webs with remarkable speed and precision, intercepting prey in just 38 milliseconds. The study highlights the spiders' ability to compare vibrations through their webs and the air to accurately target their prey.
Apple's Sound Detection feature is now available on the first- and second-gen HomePods and the HomePod Mini, allowing the smart speakers to listen for smoke and CO alarms and send a notification to your phone. The feature does not require smart smoke alarms or an internet connection, making it an attractive option for Apple Home users. The feature is free and all audio analysis is done on-device, with end-to-end encryption for remote check-ins. Amazon's Echo and Google's Nest smart speakers also have similar features, but with different limitations and requirements.
