Deafness is an invisible and isolating handicap and very often, the failure to detect deafness at an early age results in a deaf child growing up as a mute person as well. With a view to enabling the early detection of deafness, Apeejay Trust, in partnership with Pratibandhi Kalyan Kendra (PKK), an NGO from Hooghly, West Bengal, created Project Dhwani. This project saw the setting up of a Mobile Hearing Health Clinic in a van, complete with audiometric equipments. The objective was to penetrate into medically isolated geographies and help in the early identification and diagnosis of children with hearing problems. In 2010, the Apeejay Trust gifted the ownership of the van and equipment to PKK.
