Abstract

A method of enabling a hearer to hear desired sound while also being able to be aware of ambient sound, comprises providing a first non-audio signal representative of said desired sound, deriving a second non-audio signal from said ambient sound, combining the first and second non-audio signals in providing a third non-audio signal, and converting said third non-audio signal into sound.
