Audio interface to digital

[lona]

I have a device called audiometer is used for measuring hearing threshold of a person; this device presents tones at different frequencies, and at different intensity.
Need a device (interface) & software that can be connected to the output of stereo audio jack (audiometer) to capture the frequency and intensity (for given ear left/right) and plot it on the audiogram.
Example; plot for the right ear at 1KHz is 35db & at 2KHz is 40db & at 3KHz is 45db & at 4Khz is 50db
Audiometer ;
Frequency levels are from: 125Hz, 500Hz, 750Hz, 1 KHz, 1500 Hz, 2 KHz, 3 KHz, 4 KHz, 6 KHz, 8 KHz
The intensity levels are from: -10db to 120db (in 5db steps incremental )

Please let me know who can build it ?

Are you looking for someone to design this for you?

 

[lona]

Yes if possible, please advise

Look on the web for 'Audacity 1.3 Beta', its a PC program that will capture and display audio files.
Its a freedownload.

Plug your audiometer into the PC 'aux/line' audio input

Thank for the link but this is for recording and editing sounds my requirement is different.
Need some one to design it

 

[blueroomelectronics]

What's your project budget?

PS it will be far less expensive to find software for your PCs soundcard than any custom hardware design.

 

[lona]

We can discuss the cost of the forum if you can provide me a link for discussion

 

[blueroomelectronics]

Are you going to use a PC or Netbook with sound card or want a custom embedded solution?

 

[lona]

I will be using PC and netbook

 

[blueroomelectronics]

Then perhaps a programmers forum will get you faster results. Mostly electronic types here.

Not sure but Labview programmers may be able to do this.

 

[lona]

This job is to design hardware(interface) first, that get connected to audiometer , then PC software

 

[blueroomelectronics]

You need to find a microphone that will fit your requirements. A decent sound card will have a good microphone input.

 

[lona]

Not sure I can follow what you are saying, can you or any one can do this design work, and get paied.

 

[Nigel Goodwin]

You just need a standard 3.5mm stereo jack lead from the audiometer to a PC, then PC software to do what you want - no 'design' involved.

 

[lona]

No it does require a new design. if some one can help me on the design please let me know.

 

[blueroomelectronics]

Why would it require a new design? What's wrong with using a microphone?

 

[Nigel Goodwin]

No it does require a new design. if some one can help me on the design please let me know.

Well you don't give any indication of what you want - what EXACTLY is it?.

 

[lona]

This is my requirement to design the device as per my specifications,
Microphone or audio jack to pc will not do the job.
have a look what is audiometer or I can provide you with that,

 

[blueroomelectronics]

Ok so it's a school project.

You haven't given any specifications?.
