I was recently a juror at a trial. For the “approach the bench” moments i expected them to use sound masking. They didnt - they just talked quietly. What you describe sounds obnoxious. If you’re in USA and the company is big enough, then Americans with Disabilities Act could help you. Is there a way to reasonably accommodate your situation? At least remove the sound from outside your office if that’s a problem area. Maybe a door instead.
