How often does the letter n occur in:
Q: How does the on-board computer answer multiple nearby people without overlap? Onboard Starfleet computers, personnel can ask the computer questions vocally and get an audio response. 
Presumably on a ship of that size, the computer is doing this in parallel all the time — e.g. telling Person A the current date in one location, while elsewhere Person B is asking for the output to some equation & Person C is looking for the location of a particular crewman.
Is there any in-world explanation for how the computer behaves if Person A, B & C are all within earshot of each other? Does it answer questions one at a time (by order asked / by rank of person asking)? Or is the audio localised somehow (e.g. via the Universal Translator) so people only hear the answer to their own question?
(Happy to get any answers with canonical references, but thinking specifically TNG/DS9-era if it makes a difference)

A: Lets look at a real world example first; Google Home. It can determine who is asking the question based on voice, if you have multiple home devices in your vicinity, it answers from the unit closest to you ( I assume based on loudness of the query picked up by each unit). My wife and I can be in completely separate rooms and be talking to the units at the same time without issue. If we ask the same unit a question, it will answer whoever asked the question first. It wouldnt be much more of a logical leap to have it queue up questions and answer them in the order they were received, but right now Google only listens/answers one thing at a time. 
On a starship we have access to a bunch of advanced sensors that can determine the location of an individual, you could narrow down someones location much more easily. From episodes of TNG/DS9/VOY, any questions asked of the computer seem to come from the console the individual is working at, or somewhere in the room if they are not working by a console. The computer could discern where the user is and from what context they are asking a query and answer appropriately, much like a Google Home unit group.
Further, the computer seems to react in the same way, answering questions in the order they were received. It does seem to respect the chain of command, a superior officer will order the computer to belay an order that was given to it and the computer will not carry out the request or query given to it previously.
Examples:
Voyager: String Theory (Novel)
Voyager: The Nanotech War (Novel)
TNG: Hollow Pursuits (TV)

A: I dont think we ever see this on TV.  If we did, the TV-viewing audience would hear separate parties making separate queries more or less simultaneously, and it would be distracting for us, nevermind the computer.
Which brings me to my answer: its possible that practicality and etiquette come into play.   If someone is playing the radio at the beach, you dont set up next to them and play your radio.  You either find another spot or learn to appreciate reggaeton.  If you find a spot still within ear shot of the other people, but far away enough that your radio can drown out most of the other music, then youre good to go.
Although there are a variety of ways the computer can distinguish between different simultaneous speakers in the same area (frequency/pitch filtering, location sensors, relative volume, spoken language, syntax, artificial intelligence, etc.) its also possible that it may just ask users to Please restate the question.
One good example of the computer using context to figure out when to respond and when not to is from TNG: Schisms.  But in that case they were working together and not talking all at once.

WORF: Computer, make the handle a single grip ten centimetres long, solid metal. Now make one blade longer, curved inward. And give the other blade a jagged edge. [Computer complies.]
TROI: All right, you were lying on the table. You had a bright light shining in your eyes. Were there any smells in the room? Were there
  any sounds? [Computer is silent.]
RIKER: Yes. Yes, there was a sound. Computer, there were noises coming
  from the darkness. Strange, like whispering.  [Computer complies.]
KAMINER: More like clicks. Clicking sounds.  [Computer complies.]
RIKER: Louder. Faster. More of them.  [Computer complies.]
