==Hearing in Noise==
The Hearing in Noise Test (HINT) measures a person's ability to hear speech in quiet and in noise.<ref>{{Cite journal | last1 = Nilsson | first1 = M. | last2 = Soli | first2 = S.

More specifically, there are four conditions: (1) sentences with no competing noise, (2) sentences with competing noise presented directly in front of the patient, (3) noise presented at 90° to the right of the patient, and (4) noise presented at 90° to the left of the patient.  The test measures [[signal-to-noise ratio]] for the different conditions which corresponds to how loud the sentences needed to be played above the noise so that the patient can repeat them correctly 50% of the time.
