Can you hear the rest of the sounds in the game? If so, perhaps you still need to trigger it and you'll hear it later. Also, are you sure you are in the womens bathroom?
Then you are not far enough in the game.. you will have to find fuses and turn on lights....first amongst other things- when you are in the bathroom-- the fist stall click on it you should hear the word here--- use the flashlight that is in your items-- they give it to you.. click on it and you can see. Hearing the work here tells you to use the flashlight - do you know where the flashlight is?
yes it is in the cell phone- on the stall to the left-- you should hear something- click on the flashlight and it should light up that stall. maybe then you can get into the second stall. but you must of gotten into the first stall if you got the wrench right

Then turn the dial for the next number so that it is under the arrow again and then press enter button - and so on until all number have been placed under the arrow and entered.
