Title:
NOISE REDUCTION CONVERSATION SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/036154
Kind Code:
A1
Abstract:
The present invention relates to a noise reduction conversation system, comprising a receiver-transmitter provided in a control room, and an acoustic-electric conversion device provided in a scanning room and an air conduit microphone headset connected to same, wherein the receiver-transmitter is connected to the acoustic-electric conversion device, the air conduit microphone headset is used for voice communication between the control room and the scanning room, and the air conduit microphone headset is provided with a noise reduction module after an acoustic signal of the acoustic-electric conversion device is converted into an electric signal. The present invention can not only implement bidirectional wireless transmission of voice information between the control room and the scanning room of nuclear magnetic resonance, but also can reduce the noise of the voice information received by contents in the control room and the scanning room, thereby improving the quality of voice transmission.
