If you have calibrated the audio according to the instructions, then hearing a faint whistling sound will most likely be accounted for by either or both of the following possibilities:
1. You have exceptional high frequency hearing (which can be genetic, a function of your frame size being smaller than normal, or you being young in age).
2. Your laptop speakers are marginal in frequency response for playing sounds of the pitch I use. Most speakers tared for 20 kHz are capable, but some are marginally capable, and this makes the audio a bit easier to hear because of the added speaker distortion caused by that fact.
I hope you made measurements before you started.
