Subject: Re: [AUDITORY] suggestion on screening hearing ability application From: Bob Masta <audio@xxxxxxxx> Date: Tue, 27 Feb 2018 08:49:13 -0500 List-Archive:<http://lists.mcgill.ca/scripts/wa.exe?LIST=AUDITORY>I have long considerd adding such an application to my Daqarta software, but the problem is headphone calibration. There would probably be no point to an application that required you to buy a specific model of expensive headphone, one that was readily available and likely to continue in production in the exact same form, such that I could provide a calibration curve and be assured that the headphones you bought would be comparable. Cheap consumer headphones seem to come and go, continuously morphing in style. Worse, many of the modern styles might be hard to calibrate in a meaningful way without in-ear measurement, since their position on or in the ear can have a big effect on response... they don't provide a natural alignment such as the old circumaural styles. (Even those had serious variablity at low frequencies due to leakage, but at least the problem frequencies were lower than the ones you are probably most concerened about.) Daqarta already provides the means to do the calibration, but of course that requires a calibrated microphone, not to mention the need for some sort of standard coupler. I'd be interested if anyone can suggest candidate phones that are available, not too expensive, and have a stable production history. Or any other ideas on resolving this issue.... <g> Best regards, Bob Masta =3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D=3D= =3D=3D=3D=3D=3D=3D=3D On 26 Feb 2018 at 13:53, Amirmasoud Momenipour wrote: > > Dear colleagues, > > To be able to screen the hearing ability of my participants in a study t= o include only normal hearing > individuals, I was wondering if there is any legitimate software/applica= tion/online tool that could do > simple and basic=A0audiometry. > > I have found a few online but am not sure how reliable their results are= .
