)

`baserate_hp`	Sets the (estimated) prevalence of headphones in the target population as a number between 0 and 1. Defaults to the unbiased prevalence B of 0.1767 from \insertCiteHALT_2;textualHALT.
`devices`	Sets the desired playback device. Possible settings are `"HP"` for headphones or `"LS"` for loudspeakers.
`switch_to_target`	Sets the (estimated) switching prevalence. The switching prevalence describes the probability that a participant who indicates the use of a device other than the target device actually switches to the target device after being prompted to do so.
`min_number`	minimum number of participants passing the test procedure and using the target devices
`min_prob`	minimum probability (equal to or greater than 0.6, less than 1) for the event that at least `min_number` participants pass the test procedure and use the target devices.
`tolerance`	(non-negative integer) defaults to `0`. A value of 0 searches for the screening procedures with the minimum sample size. If set to a value > 0 the function returns the screening procedures whose sample sizes exceed the minimum sample size by at most this value.
