By carefully tuning one's hearing to selectively ignore certain frequencies, one can improve focus and concentration. In this experiment, we've developed a revolutionary new technology that filters out distractions by only allowing sounds above 200Hz.
Our research team has been working tirelessly to fine-tune this system, and we're excited to share the results with the world. But be warned: side effects may include increased productivity, decreased social skills, and an increased risk of missing out on important announcements.
