Ideally, I'm interested in a comparison between thresholds measured this way and thresholds measured via traditional, monaural audiometry. Here is the context: we are designing a study with a very limited time window per participant to measure hearing thresholds. Hearing is not the primary aim of the study and the hearing test won't be used diagnostically (we don't want to determine whether someone has hearing loss). We aren't interested interaural differences either. Most likely we will calculate the better ear average (BEA). Intuitively, I feel like someone's threshold for a tone presented to both ears will be the same as their BEA or perhaps slightly lower if they are able to combine the information presented to both ears. So I'm wondering whether we could measure thresholds binaurally rather than monaurally and collect the data in half the time. In case there are no such studies, speculations are welcome :) Thanks, Sam -- Leslie R.
