How does ChatterBlocker stop noise with more sound?
Our goal is not to stop noise by adding more noise. The goal is to render speech less intelligible, because intelligible speech tends to be the most distracting sound in the workplace. If we can understand the conversations around us, our minds tend to lock onto those conversations and we lose track of our own thoughts. ChatterBlocker doesn’t “stop” noise — it reduces the intelligibility of nearby conversations to make them less distracting. This is done using auditory masking, the same psychoacoustic phenomenon exploited by MP3 and related compression algorithms. Intelligible speech is hidden behind similar, but less distracting sounds. The result isn’t silence but a relaxing murmur. The effect is similar to lying on a crowded beach, where faraway voices mingle with the sounds of the surf to lull you into a state of relaxation. This state allows you to calm the body and focus the mind.
