I was the Captain on Aircraft X from ZZZ to ZZZ1 on Date. Just about top of descent both the FAs (Flight Attendants) and both pilots heard a high pitched squealing sound and the FAs believed it was coming from Door R1 near the floor.The FAs also reported a vibration in the floor at the bottom of Door R1.The FAs never reported smelling anything.About a minute after the sound started the FO (First Officer) thought he might be smelling something coming from his gasper vent on the forward instrument panel. I couldn't initially smell anything but possibly a few minutes later might have briefly but if we did it was very brief and minor. The FO described it as a hot plastic type of smell but very faint and for just a couple of minutes.The squeal and vibration lasted about 10 minutes and the rest of the flight was uneventful.I filled out an odor form for MX (Maintenance); they said it would help them troubleshoot our issue and therefore I also am filing a report.
A320 Captain reported experiencing a 'brief' fumes event at the top of descent. Simultaneously; the flight Attendants reported a temporary 'high pitch squeal' accompanied by a floor vibration.
