There is a village in Indonesia where from past seven generations nobody can speak and hear. Deaf people in the village express themselves using special cultural forms such as deaf dance and martial arts and occupy special ritual and social roles, including digging graves and maintaining water pipes. Deaf and hearing villagers alike share a belief in a deaf god. Notwithstanding the biological time depth of the recessive mutation that causes deafness, the first substantial cohort of deaf signers did not occur until five generations ago, and this event marks the emergence of Kata Kolok. Kata Kolok (literally “deaf talk”), also known as Benkala Sign Language and Balinese Sign Language.
The village has a population of some 3,000 people, who are mostly farmers, and is located 250 meters above sea level, 17 kilometers from Singaraja town. There are two hamlets in Bengkala: Banjar Adat Bengkala Kajanan and Banjar Adat Bengkala Kelodan. Kelodan is also called Desa Kolok or Desa Bisu, which literally means the mute village.
