The noise I had gotten with my 20 yr. old Nutone exhaust was awful. Instead of a rotary fan blade this unit uses a balanced plastic squirrel cage and makes very little noise. It's just the sound of air flow, and it's soft and wouldn't have any effect on your concentration or listening ability. The old rotary fans make rumbling sounds related to the rotary design. The fan I had was replacing was connected to a 4 inch plastic duct pipe to the outside. I had to pull it out and replace it with 6 inch metal flex air pipe. Sometimes you may be able to duck tape the new pipe needed for this fan to your existing pipe, and use the existing pipe to tug the new pipe in place as you pull the old pipe out. The extra work is worth it if you want the vapors removed fast and with very little sound. Another little know fact: Old bathroom exhaust fans have been documented to start fires. It happens when the fans are left on all the time and develop a heavy load of internal dust. The old motor bearings will fail and lock the rotor. They have been known to over heat without blowing a breaker, and catch the internal dust on fire. I know of 2 drug stores not so far away where his happened. In both cases the resultant fire caught the dust on fire, the dust caught the plastic cover on fire, then the melting burning cover fell to a Terazzo floor with no combustibles, and burned out with the door to the toiled closed. Don't let this be U, might not be so lucky.
