A din is a loud, harsh sound (that's usually made by lots of things at once).
Part of speech:
It's the countable kind: "a din," "the din," "this din;"
but we don't often talk about plural dins.
None are in common use today.
How to use it:
Often we talk about the din of something:
the din of traffic,
the din of the city streets,
the din of construction,
the din of the chattering birds,
the din of fussing toddlers,
the din of angry voices,
the din of a frat party,
the din of the cheering crowd in the stadium,
the din of an open office space sliced into a hundred cubicles,
the din of my neighbours remont.
You can shout above the din or hear something above the din. A sound can get lost in the din, or rise above (or cut through) the din. And you can talk about things that form, raise, or produce a din--or about people who silence the din.
Sometimes we add an adjective: a muffled din, a roaring din, a reverberating din, a shrieking din, a deafening din.
You can even get figurative: the din of the nightly news, the din of arguments on Twitter, the din of accusations and recriminations.
Finally, it's rare today, but if you're trying to sound poetic, you can use "din" as a verb. Here's Isaac Asimov: "The metal walls dinned back the clangor of his steps." And William Wordsworth: "The bag-pipe dinning on the midnight moor."
examples: My daughter's tiny voice disappears in the din of the crowded restaurant.
It wasn't until the people's demands for an investigation escalated into a din that the government acquiesced.
