Narrative:

No communication report. I turned my radio receiver volume down so I could make a PA. When I finished I turned the volume back up and turned my speaker on. Immediately afterward we received 2 calls from the cabin concerning an ill passenger who required medical attention. The first officer left his seat to let a flight attendant into the cockpit. He was working on a reroute and got a new flight plan via ACARS. I was reviewing the flight operations manual diversion guide because of the ill passenger. We then got an ACARS message telling us to contact ATC. At that time I realized I must have hit my speaker volume when I stowed my oxygen mask. The first officer was listening to ATC on my speaker and was so busy with the new paperwork that he did not turn his speaker on. Scottish ATC told us that they would file a no communication report.
