Apple is working hard to improve the sound quality branded headset EarPods, suggests a new patent application company. The document says that the experts from Cupertino are preparing a special noise reduction system based on the built-in headphones sensors.
This week, the Office of Patents and Trademarks United States published patent application from Apple entitled “Methods and techniques for using the accelerometer signals and microphone to improve voice quality in mobile devices.” The company’s specialists suggest using a range of sensors to improve sound quality. In particular, it is proposed to use the headphones two microphones and an accelerometer.
Apple has noted that a high level of noise is one of the most frequent complaints of user’s headsets and headphones with built-in microphones: simultaneously with the voice of a man in a sound channel reach and the surrounding noise. They are superimposed on the voice and significantly degrade the quality of voice communications.
Special technology provides for the integration of the sensor into each cup EarPods. Thanks to this sensor and two built-in microphones, the headset can detect voice activity of the person and provide the function of active noise cancellation. Apple has argued that this technology can effectively cope with extraneous noise during a call, reducing ambient noise up to 95%.
Built-in headphone accelerometer will detect the user’s speech on the basis of its vibrations of the vocal cords. In combination with the acoustic signals from microphones technology will identify a person’s voice and eliminate background noise.
Patent under number 20140270231 was registered in March 2013. Inventors are two staff Apple – Sorin Dusan and Aram Lindahi.
