They are marked by the presence of noise or silence during the constriction phase.
An obstruent is a speech sound produced by obstructing airflow in the vocal tract, resulting in a complete or partial blockage that creates noise or friction. Unlike sonorants (such as vowels, nasals, or liquids) which allow air to flow relatively freely, obstruents are defined by their "tight" or "hissy" acoustic properties. Categories of Obstruents
Air is forced through a narrow passage, creating friction (e.g., /f, v, s, z, ʃ, h/). obstruent
A combination that begins like a stop and releases into a fricative (e.g., /tʃ/ as in "church," /dʒ/ as in "judge"). Key Characteristics

Air is blocked completely and then released (e.g., /p, b, t, d, k, g/).
Obstruents frequently occur in pairs—one voiced (vocal folds vibrate) and one voiceless (no vibration)—such as /s/ vs. /z/ or /t/ vs. /d/. Categories of Obstruents Air is forced through a
In phonetics, obstruents are divided into three main "flavors" based on how the air is managed:
