[GS Paper III: (Science & Technology – Developments and their applications and effects in everyday life)]

On July 17, the Ministry of Science and Technology & Earth Sciences launched an indigenously developed newborn hearing screening device – SOHUM. 

  • Developed under the School of International Biodesign (SIB) program of Department of Biotechnology (DBT), the diagnostic device is non-invasive (which means babies do not need to be sedated) and cost-effective. 
  • Sohum uses brainstem auditory evoked response, the gold standard in auditory testing to check for hearing response in a newborn. 
  • Congenital hearing loss is a result of both genetic and non-genetic factors and affects 8,00,000 new born babies globally, of which nearly 1,00,000 are in India.
  • Once available in market, Sohum will to cater to nearly 26 million babies born every year in India and will help minimize incidents of hearing impairment through early detection.
Note: SIB is a flagship Program of the DBT aimed to develop innovative and affordable medical devices as per unmet clinical needs of India and to train the next generation of medical technology innovators in India. It is implemented jointly at AIIMS and IIT Delhi in collaboration with International partners.

PT Facts:

  • For human ear, the range of audible frequencies is roughly from 20 to 20,000 Hz.
  • The inner ear called labyrinth, is an important part of our vestibular (balance) system. The labyrinth interacts with other systems in the body, such as the visual (eyes) and skeletal (bones and joints) systems, to maintain the body's position.
  • Labyrinthitis (an infection or inflammation of the inner ear), Ménière's disease (an inner ear fluid balance disorder) and the Vestibular neuronitis (an infection of the vestibular nerve) are some of the balance disorders associated with ear malfunctioning.
