Bangalore-Based Inventor Develops Low-Cost Device To Test Hearing Ability Of New-Borns
At present, there are two predominant systems of screening in India. The first one is called Otoacoustic emission (OEA) which is used to detect any blockage in the canal of an outer ear and any damage to outer hair cells in the cochlea. It is conducted by placing a microphone in the infantâs ear, then the sounds are played and an echo from the ear is measured. Second system is Auditory brainstem response (ABR) also known as Auditory evoked potential (AEP) uses disposable electrodes. The test is conducted by placing electrodes on the head and recording brainâs activity in response to the sound. The former is sensitive to outside sounds and does not perform efficiently in India as the environment is generally noisy and the latter costs about INR 5-8 lakhs.
The novel device similar to ABR technology is still in a prototype phase and will most probably be available in the markets in 2017. It is estimated that the new system will be sold at about one-fifth of the price of the ABR equipment. The algorithm for the device is written in such a way that it can work on sleeping babies and there is no need to sedate them. While using the device, the presence of skilled technicians is not required.
Neeti Kailas also planning to conduct hearing screening awareness programs since lack of awareness is another issue along with the cost of the test. The team is also in talks with doctors and experts to understand their concerns.
