New Noise-Cancelling Headphones May Be the Answer to Noise Pollution

Noise pollution is a huge problem around the world, and the detrimental effect it has on humans is no secret. People exposed to more than 70dBA on a continual basis are likely to suffer from noise-induced hearing loss and a plethora of other health problems, including stress and heart disease. Noise-cancelling headphones have been on the market for years and are relatively effective at taking the edge off of unwanted noise. But their technology remains somewhat stagnant, until recently.

Enter Doppler Labs and Hear Active Listening
Doppler Labs, known for making some of the most advanced headphones on the market, recently announced a Kickstarter campaign for a new noise-cancelling system, dubbed “Here Active Listening.” These Bluetooth earbuds will feature brand new, never-before-seen technology.

Unlike traditional noise-cancelling headphones, users of the Hear Active Listening system will actually be able to customize the ambient sounds. Using the ear buds in combination with a Smartphone app, users can control the volume of sounds, mix sounds, and even add sound effects. The system will come with a host of preset filters to cancel out specific sounds. If a user is on an airplane with a crying baby or subjected to the obnoxious screeching of a train, they can simply apply the custom-designed filter to block out that specific sound.

The way the technology works is through a series of algorithms that process external signals. The incoming sounds are analyzed and played back in fewer than 30 microseconds. Here Active Listening then uses the analysis of the sound to target and resolve specific frequencies. So, it is able to effectively modify specific pitches with tailored “cures.”

Once the company reaches its Kickstarter goal of $250,000, Doppler Labs will be a pioneer of the marketplace with this incredible new technology. That means many of us will be able to say goodbye to noise pollution forever, or at least while we’re wearing our Hear buds.
