Hearing
Definition:
(p. pr. & vb. n.) of Hear
(n.) The act or power of perceiving sound; perception of sound; the faculty or sense by which sound is perceived; as, my hearing is good.
(n.) Attention to what is delivered; opportunity to be heard; audience; as, I could not obtain a hearing.
(n.) A listening to facts and evidence, for the sake of adjudication; a session of a court for considering proofs and determining issues.
(n.) Extent within which sound may be heard; sound; earshot.
Example Sentences:
