Hello New Kitchen and thank you for the feedback you posted on the Home Depot website about your new Moen Host Series 3/4-HP Continuous Feed Space Saving Garbage Disposal with Sound Reduction and Fast Track Installation. The noise level of the installed disposal will be influenced by installation conditions. Because of this, perceived noise levels will vary. The SoundSHIELD™ insulation used on the Host Series 3/4-HP Continuous Feed Space Saving Garbage Disposal with Sound Reduction and Fast Track Installation is a technology that is designed to provide sound deadening insulation. With regard to the noise you hear at start-up, this is the motor turning on and the impellers clicking/hitting against the wall of the disposal as they begin to move/start the grinding process. With continued use, this start up noise will soften over time. Our product specialists are available for pre-purchase, installation and warranty assistance. They can be reached at 1-800-289-6636 and are currently available Monday through Friday from 8:00 am – 7:00 pm Eastern Time.
