In one example, a method for masking open space noise includes outputting a test signal from a speaker, the test signal operable to measure a speech transmission quality of a transmission channel. The method includes receiving the test signal at a microphone, outputting a detected test signal, and processing the detected test signal to determine the speech transmission quality of the transmission channel. The method further includes adjusting an output level of a noise masking signal from the speaker responsive to the speech transmission quality."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Speech intelligibility measurement and open space noise masking","description":"Methods and apparatuses for addressing open space noise are disclosed.
