Discrimination between test and reference rippled sound signals with overlapping additional signals was measured. In the
test signal, ripple phase inversed every 400 ms. The reference signal had either a rippled spectrum with the same ripple
density as the test or a spectrum with unresolvable ripple pattern. The additional signal had the same spectrum band as
the test and reference signals, either flat or rippled 2 to 7 ripples/oct. With a rippled reference signal, the ripple-
density resolution was 8.7 ripples/oct in control (no additional signal), 8.5 ripples/oct with a flat additional signal,
and 8.6 to 9.2 ripples/oct with a rippled additional signal) of 2 to 7 ripples/oct (all insignificantly differing from
control). With a noinrippled reference signal, the ripple density resolution was 51.0 ripple/oct in control, 16.7
ripples/oct with a flat additional signal, and 11.0 to 11.1 ripples/oct with a rippled additional signal 2 to 7
ripples/oct (all significantly differing from control). The conclusion: overlapping additional signals result in
specific effects depending on the spectrum pattern of the additional signal, with these effects differing for spectral
and temporal mechanisms of frequency analysis.
