the sound of your key being inserted into the lock gives attackers all they need to make a working copy of your front door key.

Acoustic transparency
As if all contemporary buildings have tinnitus
acoustic transparency is a quality of ambience—what became known as the “atmosphere” of a space. Very often, you can observe that once rooms are silenced, other sounds are introduced artificially because, in the end, total silence doesn’t feel comfortable.
Metamaterial Noise Cancellation
Acoustic metamaterial and noise cancellation device capable of blocking 94% of transmitted sound energy while preserving air flow
A Better Way to Cancel Noise
It exploits the fact that wireless signals travel faster than sound. The receiver could pick up the construction noise and beam the anti-noise signal to the MUTE earpiece before the sound has enough time to hit his eardrum
Inaudible voice attacks
We test our attack prototype with 984 commands to Amazon Echo and 200 commands to smartphones – the attacks are launched from various distances with 130 different background noises. Attack success at 8m for Amazon Echo and 10m for smartphones at a power of 6 watt.
ASMR
W Magazine recently recruited Parks And Recreation and Legion star Aubrey Plaza for its ongoing, aurally uncomfortable video series, “Celebrity ASMR,” which is exactly what it sounds like. But where folks like Jake Gyllenhaal, Margot Robbie, and Gal Gadot only paid loudly-smacking lip service when they sat down way too close to W’s mics—posting videos a mere 2 or 3 minutes in length—Plaza approached the task with the same intensity with which she appears to tackle pretty much everything in her life, laying down a 36-minute sonic odyssey in search of “the tingles.” Also, a lot of it was about how much she still hates Jerry.
The shushing sound of voices whispering, or clothes rustling—and then a tingling feeling begins on the scalp, and spreads down into the neck, shoulders, and limbs, and along with it comes a state of calm, or even euphoria. This is how people who experience autonomous sensory meridian response, or ASMR, describe the peculiar phenomenon. ASMR is “similar to the deep relaxation someone might feel if they’re getting a massage”. It’s a form of auditory-tactile synesthesia; “brain tingles.”
Window Noise cancelling
using the glass as the resonator for destructive interference. seems plausible, though perhaps a bit exaggerated in its effect. more details. i liked that there was no kickstarter and groaned at the alleged e-smog pollution this helps clear up too.
House Music
Soundscapes for every life situation
Why have a housemate when you can simply listen to endless loops of air-conditioning units, refrigerator hum, distant TV voices, pet sounds, keyboard clacking, footsteps over hardwood floors, and more? The specially curated Household Collection has it all (almost), including someone “handling a wallet,” “peeling a rubber glove off,” and “opening a bedroom door.” There’s also Household Collection 2.
Fingerprinting Phone Calls
yet another application for white noise analysis, this time to serve as a caller / route id for calls.
The tool is called PinDr0p, and works by analysing the various characteristic noise artifacts left in audio by the different types of voice network — cellular, VoIP etc. For instance, packet loss leaves tiny gaps in audio signals, too brief for the human ear to detect, but quite perceptible to the PinDr0p algorithms. Vishers and others wishing to avoid giving away the origin of a call will often route a call through multiple different network types. This system can be used to differentiate telephone calls from your bank from telephone calls from someone in Nigeria pretending to be from your bank.
Electrical frequency analysis
a forensic technique for validating audio recordings by comparing frequency changes in background mains hum in the recording with long-term high-precision historical records of mains frequency changes from a database. In effect the mains hum signal is treated as if it was a time-dependent digital watermark that can be used to identify the time at which the recording was created, and to help detect any edits in the sound recording.
