Theta

Voiceless dental fricative.

When we pronounce this sound, the tip of the tongue, the active articulator , is placed between the upper and lower front teeth, the passive articulators.The velum is in its raised position. So, the lung air cannot go out through the nasal cavity. Friction is produced when the lung air goes out through the passage formed by the articulators. The vocal folds do not vibrate during the production of this sound.
