If you say someone is 'making all the right noises' it means that they are showing concern or enthusiasm because they feel they are expected to rather than expressing a genuine feeling or emotion. Someone who 'makes all the right noises' says or does the correct things in order to convince others of their position.

1. When I asked for Kevin's opinion on my new car, he made all the right noises, but I could tell by looking at him that he wasn't impressed.
2. The politician knows how to make all the right noises to convince people to vote for him, but I don't think he really means anything he says.

1. Our boss made all the right noises about improving our working conditions, but in the end it never actually led to anything.
2. So far she seems to be making all the right noises, but only time will tell if she will make a good CEO or not.
