Working in a small co-work space, the current office manager constantly and repeatedly (every 10 seconds approximately) produces loud noises (mostly [tics][1]) when not engaging in a conversation. A few examples:

- clearing his throat;
- knocking on the table with his knuckles;
- teeth whistling (to mimic the sound of birds);
- horse hoof sounds mimicking (with his tongue)...

These grew in their frequency and intensity since I started working in this place and I am sure I am not the only person being disturbed by these (there is a person sitting right on the same table working on a computer most of the day).

I rarely talk to this manager (a few greetings and very few office related topics, that's all) and I am working on a nearby room, but the sound propagates so well in this office that it is as if I am listening to these sounds right in the same room. Moving to another place is currently not an option.

I always used headphones and recently I started placing head muffs (proper hearing protection) over them, but still some of these sounds are clearly audible. These have been literally _ticking_ me off more often than I'd be glad to admit to, but I never approached this person about this issue (no other person from this co-work space did, I believe).

Only one colleague and friend of this person tried using a shushing sound one day they were together, but still there were no _audible_ results.

I do not want to upset this person, since this manager is the main responsible for the space I am working in, but if I were to approach this subject, how should I do it?
