Key result
Different phases of the cardiac cycle had no measurable effect on auditory sensitivity or response bias during signal detection tasks.

No cardiac cycle adjustment needed in auditory testing; leaves open whether interoceptive effects exist in other domains or tasks.
Does the phase of the cardiac cycle affect auditory sensitivity or response bias?
The phase of the cardiac cycle does not appear to influence auditory sensory capacity or response bias, suggesting 'cardiac cycle arousal effects' are minimal or nonexistent.
Delfini et al. (1972) studied this question. Different phases of the cardiac cycle vs. Other phases of the cardiac cycle was evaluated on Auditory sensitivity and estimate of response bias. Different phases of the cardiac cycle had no measurable effect on auditory sensitivity or response bias during signal detection tasks.
