    SYLLABIC (or fast compression) Syllabic compression adjusts the gain for instantaneous fluctuations that occur within speech. It operates with a fast level meter using an attack time of 10 ms and a release time of 100 ms. It should be used in frequency bands where a user has a strongly reduced dynamic range (moderate to severe hearing loss) which is more common in the high frequencies.
