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:

External Mentor:

Mr. Chandrashekar ,Magnum Technology,Jayanagar,Bangalore,India

Hi vishal,
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!
