Dear David,
there are different approaches applied in different studies, for example:
- set volume of the device to achieve a comfortable level, where speech is clearly heard/understood (sometimes that is connected
to the assumption of corresponding to approx.. 65 dB) (e.g. in Perugia et al. JASA 2026, Motlagh Zadeh et al. Int. J. of Audiology 2025, Lad et al. JMIR 2024)
- set volume of device to a specified point, e.g., 50% or 100% (e.g., Vercammen & Strelcyk Trends in Hearing 2025, Mui et
al. J AM Acad. Audiology 2025)
- “biological calibration” (e.g. Masalski et al. JMIR 2014, Honeth et al. Oto & Neuro 2010)
We have also done remote speech in noise measurements with individual uncalibrated hardware and also used the first approach. That worked quiet well, especially because the outcome
measure refers to the SNR, knowing the absolute levels very accurately is not so crucial. We have also started some work on estimating device specific calibration values using parameters from uncalibrated categorical loudness scaling, which looks promising
but did not lead to a validated procedure so far.

Betreff: [AUDITORY] Level setting with headphones + own device
ACHTUNG! Diese E-Mail kommt
von Extern! WARNING! This email originated off-campus.
Dear auditory colleagues,
Is anyone aware of a robust volume setting procedure for when participants are doing speech perception tasks with their own devices, say with online testing (headphones
connected to tablets, laptops, etc.)?
I know there are some convincing binaural tests to check people are using headphones, but what about the overall level setting?
Best
David
