Daijirin (the Weblio ref Brian quotes): (1) 聞いて理解すること。聞いて知ること。 「 −調査」  (2) 外国語を聞いて理解すること。ヒアリング。 「 −のテスト」 
GG5: (1) hearing what others say; a gathering of verbally expressed 「opinions [information]. (2) listening [aural] comprehension.

I think it's a bit broader that "a hearing" in the sense of US Congressional ones, but they'd fit in.

First, examine this entry. It seems to match the original 
definition with no indication that it means judicial 
hearing. However, note in definition 2 that the word ヒアリ
ング (hearing) is listed.

If you check the definition of hearing, you get, among the 
definitions, 公聴会 and 聴聞会. These do translate as public 
hearing, as in court procedures. This may seem a dubious 
connection. However, examine the use of 聞き取り in the 
following article:

"トランプ氏が司法妨害を行おうとしたかどうかの捜査に関連し、ダニエ
ル・コーツ（Daniel Coats）国家情報長官やマイク・ロジャース
（Mike Rogers）国家安全保障局（NSA）長官を含む情報機関幹部が、
モラー氏のチームの捜査官による聞き取りに応じることに同意した。聞
き取りは週内に行われる見通し。"

It's clear from this quote that "hearing" is an appropriate 
translation of this word.
