The Gaps In Noise (GIN) test is an auditory processing disorder test for ages 7 and older using non-verbal stimuli. It is designed to measure temporal resolution. Temporal resolution refers to the ability to detect changes either in the duration of an auditory stimulus and/or the time intervals or gaps of silence embedded within an auditory stimulus. The ability to detect small silent intervals is an important factor in speech perception. This GIN test is a valuable test for the evaluation of this ability.
The GIN test is composed of a series or lists of noise bursts which contain various intervals of silence. The recording consists of four forms called lists plus a shorter practice list to ensure the patient understands the task. The silent intervals vary from 0 (i.e. no gap) to 20 msec. The gaps, or periods of silence, are 2, 3, 4, 5, 6, 8, 10, 12, 15 or 20 msec. There are a total of 60 randomized gaps (6 of each gap) in each list (series).
To facilitate accurate scoring the recording is two channels, one being the test track, the other, for the examiner, indicates with a brief tone when the gap occurs in the other (test) track.
The Gaps In Noise includes a) audio recording, and b) instructions and score forms as printable pdf files. The three-page instructions include information on administration, scoring, and interpretation. Normative data is included for ages 8 and up. Available from Auditec, Inc.
