Current noise cancelling technology comes in the form of headphones and earbuds. To cancel noise, these headphones emit an anti-noise signal to contrast the external sounds. The time available for the headphones to produce this anti-noise signal is extremely short. This results in some noise getting through, which is why all these devices must cover the entire ear with noise-canceling material. However, wearing such ear-blocking devices for long periods of time is not comfortable, and can even be harmful.
"Our goal is to not block the ear canal," said Sheng Shen, lead author and a Ph.D. candidate in the Coordinated Science Laboratory and Dept. of Electrical and Computer Engineering (ECE). "We envision a behind-the-ear device that still achieves noise cancellation as good as the best headphones or earbuds available today."
The main idea behind this research involves combining wireless IoT networks with noise cancellation. A microphone is placed in the environment that senses sounds and sends them over wireless signals to an earpiece. Since wireless signals travel a million times faster than sound, the earphone can receive the sound information much faster than the actual sound itself.

For an IoT to be An Internet Of Thing [twitter.com], it must have at least a) a huge security problem, b) take away a human right like privacy, c) take away money from the owner at frequent intervals for no reason whatsoever.
I good example to illustrate this is the Pay Per Wash washing machine [twitter.com]. Another good example is this fridge [twitter.com] that will give your GDPR warnings whenever you want to open it.
Whether or not it's "interactive" or "Internet" isn't the point. It has to be complete utter shit. Pointless shit. The kind of shit that your dog puts in the corner of your house.

Why get an IoT washing machine at all?
If I ever need a 13-year-old Russian kid to empty water all over my kitchen floor, I just walk round to my neighbour Boris's house and get his son to do it for me.
