Ambient sound is converted into digital signals. A processor performs active noise cancellation and/or a transformation operation that is distinct from the active noise cancellation on the digital signals. The active noise cancellation and the transformation operation transform the digital signals into modified digital signals. The modified digital signals are converted into modified analog signals. The modified analog signals are outputted as audio waves. An interior microphone is configured to output an output signal to the processor in response to receiving the modified analog signals. In response to receiving the output signal from the interior microphone, the processor is configured to determine whether the modified digital signals produce desired audio waves.

Real-time audio processing of ambient sound

Ear piece

An earpiece for real-time audio processing of ambient sound includes an ear bud that provides passive noise attenuation to the earpiece such that exterior ambient sound is substantially reduced within an ear of a wearer, an exterior microphone that receives ambient sound and converts the received ambient sound into analog electrical signals, and an analog-to-digital converter that converts the analog electrical signals into digital signals representative of the ambient sounds. The earpiece further includes a digital signal processor that performs a transformation operation on the digital signals according to instructions received from a mobile device, the transformation operation transforms the digital signals into modified digital signals, a digital-to-analog converter that converts the modified digital signals into modified analog electrical signals, and a speaker that outputs the modified analog electrical signals as audio waves.

Earplug

There is disclosed a passive acoustical filter including two or more filter elements coupled between an ambient and a listener's ear, each of the filter elements selected from the group consisting of a low pass filter element, a high pass filter element, a band reject filter element, and a band pass filter element.

Passive audio ear filters with multiple filter elements

There is disclosed a passive acoustical filter including a first filter element coupled between an ambient and an ear of a listener, at least a portion of the first filter element filled with a material in which a speed of sound is lower than a speed of sound in air.
