Innovative headphones allowing to detect sound sources in the wearer's `blind spot´
With the innovative filter element for headphones, the wearer can distinguish whether an external sound source approaches from the front or back and in general allows to localize sounds in the vertical plane. This innovation may prevent dangerous situations for traffic, for example if a vehicle is approaching in the back of the wearer. Any sound source, i.e. auditory object in the environment of the wearer can be precisely localized, especially auditory objects in the ´blind spot´ of the wearer.
Headphones are small loudspeakers worn on or around the head covering the user's ears. They allow an individual user to listen to sounds privately, as opposed to a loudspeaker that radiates sounds to anyone nearby. Headphones are electroacoustic transducers that convert an electrical signal into a corresponding sound. As a result of the Walkman effect, headphones began to be used in public places such as sidewalks, grocery stores, and public transportation in the 1980s and are now widely used in the public.
The global market for headphones was worth around USD 25 billion in 2019 and is expected to continue to grow rapidly in the coming years at a compound annual growth rate (CAGR) of about 20%. It is also assumed that consumers' increasing preference for stylish, attractive designs in particular will also boost sales.

Fields of application
Improvement of headphones, earspeakers, earphones or, colloquially, cans, circumaural ('around the ear'), supra-aural ('over the ear') headphones and also in- ear headphones, earbuds, earpieces, headsets or bone conduction headphones to avoid the so called front-back confusion
