But if you put noise on between the tone pips, you canÕt integrate them without integrating in the noise. If youÕre taking short looks, you can use the looks with the tone pips, but ignore the looks in between.
Viemeister and Wakefield
also presented the tones when there was a noise background that stopped just
when the tones were presented, but was on in the time between the tones. The
multiple integrator theory says that you would not be able to hear two tones
better than one in this situation because to add the energy of the two tones
you need an integrator that integrates for 120 ms, but that integrator will
also have to add in the noise between the tones, making it harder to hear
them. Multiple looks theory says that it shouldnÕt matter if there is noise
between the tones.
