On my OS X I can execute a beep while a beep is playing, but not during 
the first 10 to 20 ms of the beep.  The beeps are not queued, so it 
stutters if the time is too short.

And...

on mouseUp
   put the long seconds into tDummy
   put the long seconds into tStart
   put the long seconds into tEnd
   put (tEnd-tStart) into tCorrection
   put empty into field "Report"
   repeat with beepTimes = 0 to 4
     put the long seconds into tStart
     beep beepTimes
     put the long seconds into tEnd
     set the numberFormat to "0.######"
     put beepTimes & " beeps    " into beepReport
     set the numberFormat to "0.000000"
     put ((tEnd-tStart)-tCorrection) & " s    " into timeReport
     put max( (beepTimes-1)*.5 +.0005, .0001) & " s expected" into 
expReport
     put beepReport & timeReport & expReport & lineFeed after field 
"Report"
     wait 2 seconds
   end repeat
end mouseUp

This produces ...

0 beeps    0.000009 s    0.000100 s expected
1 beeps    0.000221 s    0.000500 s expected
2 beeps    0.000279 s    0.500500 s expected
3 beeps    0.500557 s    1.000500 s expected
4 beeps    1.000787 s    1.500500 s expected

Bug.
