How can I play a sound activated by a number of actions per time?

Question

How can I call a function, for example Play a sound, if I do 3 blinks in a space of 2 seconds?

if blinking_ratio > 5.7:
    cv2.putText(frame, "BLINKING", (50, 150), font, 7, (255, 0, 0))
    winsound.PlaySound("campainha.wav.wav", winsound.SND_FILENAME)

Here if I blink, the sound plays... I want to play, only if I blink 3 times in 2 secs for example...

You could set up a Time class by using

class Time(datetime.tzinfo):
  def utcoffset(self, x):
    return datetime.timedelta(hours=-5) + self.dst(x)

  def dst(self, x):
    date = datetime.datetime(x.year, 3, 8)
    self.dston = date + datetime.timedelta(days=6-date.weekday())
    date = datetime.datetime(x.year, 11, 1)
    self.dstoff = date + datetime.timedelta(days=6-date.weekday())
    if self.dston <= x.replace(tzinfo=None) < self.dstoff:
      return datetime.timedelta(hours=1)
    else:
      return datetime.timedelta(0)

  def tzname(self, x):
    return 'Time'

def timeStamp():
  return datetime.datetime.now(tz=Time()).strftime('%Y-%m-%d %H:%M:%S')

From this, you could do something like

while . . .:
  start = timeStamp()
  blinkOnce()
  end = timeStamp()
  if start - end < 2:
    pass
  else:
    break

Of course you would adjust the second code segment to whatever conditions you want to be met, but the end is just some pseudocode that you could edit accordingly.
