The sound that you are describing is a'click' that is heard when there is a problem in the temporomandibular joint (jaw joint). Don't worry, it can be managed. But a thorough clinical examination and radiographic assessment of the joint (x rays) are important. I would advice you to consult an oral and maxillofacial surgeon for a detailed examination and further treatment.
