Hello all and thank you for your replies so far.... I just wanted to clarify my question...
I am totally aware of the need to calibrate and the reason this question has come about is because I want to make sure I do things "right". My main question was what can the companies do to calibrate the USB versions of our equipment. In the "old days" it was easy, hitch up a simulator and off you go, but now a usb audio is only a headset and a computer program, and the technicians at the hospital that I employed to do the calibration were at a loss as to what to test / do.....
My question really was, how can people calibrate a computer program... some companies charge £150 per item... and if this is just a visual check for leads and so on and they cannot physically calibrate the tones etc, then why pay the money? I would rather pay the £50 per hour that my local hospital technicians charge ( no matter how many items they check).
I can see the need to check a spiro as there are more parts that can go wrong, but again I was told that as long as I was doing my own checks on a regular basis ( self testing and using a 1 or 3 litre syringe) then this would be sufficient.. so what would the individual who was doing the calibration do differently.
Warm Regards
Lyndsey

Subject: Re: [OCC-HEALTH] Calibration of Equiptment
Calibration us necessary and needs to be done to ensure your equipment is working within the guidelines. This is especially important if you do medicals for Railway workers as they ask for evidence your equipment is checked regularly on the annual audits. The audios can sometimes need tweaking to ensure they are recording within frequency ranges as they can alter Ideally you should do at least weekly checks on equipment yourself as best practice. Alcometers if you use them need 6 monthly calbrations
