20090161883 | SYSTEM FOR ADJUSTING PERCEIVED LOUDNESS OF AUDIO SIGNALS - A method of adjusting a loudness of an audio signal may include receiving an electronic audio signal and using one or more processors to process at least one channel of the audio signal to determine a loudness of a portion of the audio signal. This processing may include processing the channel with a plurality of approximation filters that can approximate a plurality of auditory filters that further approximate a human hearing system. In addition, the method may include computing at least one gain based at least in part on the determined loudness to cause a loudness of the audio signal to remain substantially constant for a period of time. Moreover, the method may include applying the gain to the electronic audio signal. | 2009-06-25 |
20090161884 | ETHERNET ISOLATOR FOR MICROPHONICS SECURITY AND METHOD THEREOF - A system and method for providing microphonic isolation on a transmission line. The transmission line has a first part and a second part. The first part of transmission line carries a data signal and a microphonic signal. The microphonic signal has frequencies that include those in a range of substantially 20 Hz to substantially 20 kHz. The system includes an isolation apparatus. The isolation apparatus has an input in electrical communication with a first part of the transmission line, an output in electrical communication with the second part of the transmission line, and a filter in electrical communication with the input and the output. The filter is arranged to substantially remove the microphonic signal received at the input from first part of transmission line and pass the data signal to the output. | 2009-06-25 |
20090161885 | Component for noise reducing earphone - An active noise reduction (ANR) component for provision in an earphone housing is disclosed. The device includes a driver and a sensing microphone, the driver and sensing microphone being housed in a component housing. The earphone housing has an outlet passageway from the ANR component to an auditory canal. The ANR component is adapted for use with a controller to provide active noise reduction to the auditory canal over a predetermined range of physical dimensions or acoustic parameters of the housing outlet passageway. The ANR component can thus be used with different housings which simplifies the design process for producing ANR earphone products. | 2009-06-25 |

The auto gain control unit sets the gain in the variable gain amplification unit when the amplitude of the output signal is equal to or below a predetermined reference value. | 2009-06-25 |
20090161889 | DYNAMIC RANGE CONTROLLER - A circuit for preventing clipping in an Automatic Level Control (ALC) or Limiter, where the amplitude of the signal above the clipping point is estimated, then the signal level is automatically reduced over a defined period substantially equal to the feedforward delay in the ALC/Limiter. By adaptively controlling, based on the excess amplitude and the delay time available, an attack rate used in the ALC/Limiter to reduce the gain applied to an input signal, it can be ensured that the output amplitude is brought within the clipping level sufficiently quickly to prevent audible clipping. | 2009-06-25 |
