If I want to use a vacuum for day cleaning: How quiet does it need to be?
In this article, industry manufacturers answer common questions asked by building service contractors.
The U.S. Green Building Council’s LEED certification requires that a vacuum be under 70 dBA in order to qualify for the IEQ credit. This should be sufficient for most schools and hospitals. In facilities where peace and quiet are critical, a vacuum with two modes can be used, a power mode for after hours cleaning, and a quiet mode that runs at just 51 dBA for daytime. A normal conversation is around 67 dBA, so these vacuums are practically invisible to building occupants.

At minimum, day cleaning operations require quiet, commercial-strength vacuums that operate below 70 decibels, so staff can clean day and night with less impact on the workers around them.

This is dependent on the facility that is being cleaned. Every facility that goes to day cleaning wants a lower sound level, which all manufacturers are striving to achieve. The challenge is the trade off, since reducing sound levels also reduces cleaning effectiveness of the vacuum cleaner; in most cases, small motors and reduced air flow are required to achieve needed sound levels for day cleaning.
