MY FINAL YEAR PROJECT ( 2013 ) : HAND - HELD AUDIOMETER
The Project i will be working on with my group members for my final year is the Hand-held Audiometer....Basically an Audiometer is a device used for evaluating a person's hearing ability...My aim is to develop an innovative and inexpensive portable digital audiometer for replacing the more costly and the much larger audiometers used in current audiology clinics.
We kept a goal to make it simple to use , compact and more importantly Eco friendly!
India is a highly populated country,an estimate of 60 million people are deaf (causes-genetic,lifestyle,work environment) and 30 million aren't aware of the fact that they have hearing loss...Hence it is very important to take a audiometric test...The test is based on a technique called Pure tone screening technique...here the patient is subjected to a pure tone ( external auditory stimulus ) and when the patient hears this,he/she will respond to the audiologist...these responses are plotted on a graph called an Audiogram.
We even managed to change the way the audiograms are plotted as well as the mode to display them...Standard Audiograms use Paper graphs but we are using LCD panel display..hence Eco friendly ( Stop using paper , Save Trees ! )...
We are also trying to add an extra feature like voice based instruction from the device itself so that it can guide the patient to personally evaluate their hearing ability...
Advantages:
Miniature version of Standard Audiometers.
Size of a cell phone,compact,easy to carry.
Even least experienced audiologist can operate the device.
High level of Accuracy.
Eco friendly
Hardware used:
AT89c51 Microcontroller and Waveform generator ( to generate desired frequency-pure tone)
Software used:
Embedded C
Internal Mentor:
Mrs. Archana Murthy,Medical Electronics,MVJCE,Channasandra,Bangalore,India
External Mentor:
Mr. Chandrashekar ,Magnum Technology,Jayanagar,Bangalore,India

Awesome idea....:)
Could you please elaborate on the electronic circuitry you used.As in at the circuit diagram level.How did you plot the graphs and stuff...very excited to know about the same!!!!
Thanks and regards!
