What's in-between silence and clamor? Sometimes, in a room for example, there's no sound except 1 person talking at times, do we still refer to that as silence. If not, what is it called? I suppose it's something between silence and clamor, but I can't think of a word? Is there a word that means almost-silence or the state of being able to hear a sound distinctly while hearing nothing else?
Which word you choose depends on the quality of the sound in the room. For example:
murmur (n): a low, continuous sound, as of a brook, the wind, or trees, or of low, indistinct voices.
Other options: buzz, hum, mutter, rumble, fizz, hiss, whir, ping, splash, whisper, babble, drone, and a few more less common words like sibilation or susurration.

(Edit_1) You may also use modifiers to adjust the relative volume of these kind of words. This gives a wider range of possible descriptors. Examples:
a loud hum
a muted roar
s sharp hiss
(Edit) Xerxes makes the fair point that none of these really describe the source of a "distinct" sound, such as "the sound of one person talking in a room". There is no single word to describe this, since of course, any kind of sound might be produced by any number of sources. In writing, it's fine to separately describe the quality of the sound and the source of the sound:
Through the wall he could distinctly hear the murmur of Jessica discussing the latest gossip with her friends, although, try as he might, he could not make out any details.
There is the concept of background noise. Although this phrase has a technical meaning when it comes to audio recordings and signal processing, that expression can also be used colloquially; it is defined by some dictionaries as:
background noise (noun)
Wikipedia has an entry for it, which says:
Background noise or ambient noise is any sound other than the sound being monitored (primary sound).
Examples of background noises are environmental noises such as waves, traffic noise, alarms, people talking, noise from animals or birds, and mechanical noise from devices such as refrigerators, air conditioners, power supplies, or motors.
If you are not paying attention to something else in the room, you can focus on the background noise and hear it distinctly.
"Silence" is complete absence of sound. If there is the sound of a person talking, even quietly, it wouldn't be called silence.
"Quiet" could also be interpreted to mean silence, but usually "quiet" would include an environment with a low level of sound. I think one person talking at a time, in a soft voice, would be accepted by most people as an example of "quiet".
I don't believe there is a single English word suitable to this purpose. I would use a short phrase to add an exception to "silent". For example: "silent but for a single voice" or "all was still except for the tapping of the hammer" or "a shrill, clear note broke the silence".
Clamor to be a mixture of enviro, mechanical, biological-based noise of the muted kind.
