Not sure mint, he might, but I'd feel I have to leave a kong for him and if he gets a whiff of one of those it overrides his desire for sleep. Then as soon as he's finished he starts yelling for me.
I've managed to get him to accept that I won't come straight away and can now leave him 10 minutes or so after he's finished chomping, but think half an hour would be pushing it - and he's not daft, he knows I'm not really in the living room with the door pulled to.
I don't know why it's such a huge thing for me and suspect I'm probably making the whole situation worse with my anxiety. He's only ever made enough noise to bother the neighbours once (that was ds2's assembly when he yelled really loudly for 45 minutes and he was in the living room - not the echoey kitchen back then) so they can't really complain and this time it will be mid afternoon, not first thing in the morning. I really don't think it's about them - it's my problem.
I am the same at night. I still have the baby monitor on, so I can intervene before he starts yelling if I hear him, because I'm so worried about him waking the neighbours at ridiculous o'clock. Thing is, I'm hypervigilant about it now and find myself hearing things even when he's asleep and keeping myself awake. 
Don't think I could be brave enough not to record him. It's better knowing - even if it's bad news, as at least I'm forewarned if the neighbours are p'd off.
I'm really looking forward to going to Ireland, as we have a big detached house with no neighbours there, so I can actually leave the monitor off, ignore him and sleeeep.
I think it's all just tied up with the loss of Oldgirl and Lurcherboy's separation anxiety. I really need to untangle it all and try to get over it.
... I caved in and bought the green feeder from Viovet, as it was so much cheaper than everywhere else. Dh will be furious though.
