Title:
HEARING DEVICE PERFORMING ANALOG FILTERING AND RELATED METHOD THEREOF
Document Type and Number:
Japanese Patent JP2014112836
Kind Code:
A
Abstract:

To provide a hearing device the signal-to-noise ratio of which is improved, by improving the processing of the hearing device under strong wind.

A hearing device 2 includes a microphone 4 for converting voice into an audio signal 5, and a preprocessing unit 6 performing analog processing of the audio signal 5. The preprocessing unit 6 has an input 8 and an output 10 of the audio signal 5, and the input 8 is connected to an output 12 of the microphone 4. An A/D converter 14 converts an analog audio signal 16 processed into a digital audio signal 18. The A/D converter 14 has an input 20 and an output 22, and the input 20 is connected with the output 10 of the preprocessing unit 6. A processing unit 24 performs digital processing of the digital audio signal 18, and a digital audio signal 26 thus processed is sent to a receiver and converted into a compensated audio signal. The processing unit 24 is connected with the preprocessing unit 6 by a connection 28, and sends a control signal 30 to the preprocessing unit 6.
