A few suggestions:

* Just after the chime sounds, in your Timer event handler, store the 
current time in an instance variable, eg
@chime_time = Time.now

* At the same time you could set a flag that indicates that the Space 
bar is now pressable...

* If the user presses the space bar within the right time, get the new 
time and deduct the @chime_time to see how long they took - this should 
give you a milleseconds result, eg:
how_quick = Time.now - @chime_time

* You can test whether the space bar is depressed when the sound is 
played by using Wx::get_key_state(Wx::K_SPACE) - see my reply to Ross
