I have a problem with presenting short tone sequences. Imagine the following situation: Subjects hear two consecutive pure tones (30 ms each) with a short blank pause (30 ms) in between. When a set of consecutive stimuli (i.e., tone, pause, and tone) are repeated twice, I observed that the first tone in the first repetition is not delivered to a headphone.
I tried different combinations of tone durations and pauses. The capability of delivering short consecutive tones seems to depend on a tone duration and pause duration.
I suspect this is a hardware problem (soundcard: Realtek® audio) and/or a stimulus loading problem?
Thanks for any help.
