Well I found out that when you pass window id to xev it does not trap
keyboard presses per-sé.  But there is another way...

Anway the following is a quick hack (in python).  It pretty much works
except it also seems to trap mouse presses.  I got the .wav file at
http://www.soundjay.com/typewriter-sounds.html

I tried using 'xset c' but it basically does nothing for me.  My guess
is that it does work it basically sends the a BELL to the console.

import sys
import subprocess

soundfile = 'typewriter-key-1.wav'

def main():
    window_id = sys.argv[1]
    cmd = ['xev', '-id', window_id]

    p1 = subprocess.Popen(cmd, stdout=subprocess.PIPE)
    while True:
        line = p1.stdout.readline()
        if line.find('atom 0x14d') > -1:
            subprocess.Popen(['aplay', soundfile],
stderr=open('/dev/null',
                'w'))


if __name__ == '__main__':
    main()
