A newly publishedpatent applicationfrom Apple describes how the company is going to address a fundamental problem with over-the-ear and on-ear headphones: They can be so effective at blocking outside sounds, they become a potential hazard when wearing them outside. The solution, according to the patent, is to engineer headphones with a series of external and internal microphones that can dynamically route outside sounds to the listener, effectively making the headphones acoustically invisible to the wearer.
In an era where more and more headphones are being marketed as havingsuperior noise cancellation, Apple’s invention would set a new level of expectation among users. Why should your headphones only be good at keeping sounds out, if they can intelligently decide to also let sounds in, when you need them to? The patent describes several key benefits of its “spatial headphone transparency” system:
We’d wager that, aside from the many benefits a system like this would offer music lovers, the patent is largely aimed at reducing the risk associated with wearing headphones. Beats, the headphone company started by Dr. Dre and lateracquired by Apple for $3 billion, launched in 2007. It more or less started the large, over-the-ear headphone trend that persists to this day. With that trend came a noticeable uptick in accidents associated with headphone use. From 2004 to 2010 — a period that straddles the Beats launch — headphone-related accidentswent up by nearly 300 percent, according to a study done by the University of Maryland School of Medicine in 2012. Every year since the study was performed, more people have becomevictims of their own lack of situational awarenessbecause of their headphones. Headphones designed to intelligently let sounds in, instead of always keeping them out, could significantly reduce the risks.
Recently, rumors that Apple will belaunching its own brand of over-the-ear headphoneshave begun to heat up, and this patent might just be a preview of how the company will use sophisticated new technology to market them. AirPhones, perhaps?
