Questions & Answers about zatsuon ga sukunai to, sensei no nihongo ga yoku kikitoreru.
Because 少ない is the plain form of an い-adjective, and the conditional と attaches to the plain form.
So:
- 雑音が少ない = there is little noise / the noise is low
- 雑音が少ないと = if/when there is little noise
By contrast:
- 少なく is the adverbial form, so it needs something after it, such as 少なくなる or 少なくて
Also, 少ない is one of those words that often works like this:
- お金が少ない = there is little money
- 時間が少ない = there is little time
- 雑音が少ない = there is little noise
So even though English might use something like little noise, Japanese expresses it as noise is few/little.
Here, が marks 雑音 as the subject of the conditional clause:
- 雑音が少ない = the noise is low / there is little noise
Using が sounds neutral and descriptive. It simply presents the condition.
If you used は instead:
- 雑音は少ないと、...
that would sound unusual here, because は introduces a topic or contrast, and this sentence is not really trying to contrast noise with something else.
In short:
- が = natural for stating the condition plainly
- は = would add contrast or topical emphasis
